Bulbophyllum yarlungzangboense​     Photos: Jian-Wu Li
Abstract: Bulbophyllum yarlungzangboense, a new species of Orchidaceae from Tibet, China is described and illustrated, it is morphologically similar to Bulbophyllum gamblei and Bulbophyllum shweliense, but can be easy distinguished from the later by petals ovate-oblong, stelidis triangular, base of column foot with V-shape cushion. The new species is tentatively assigned to sect. Desmosanthes based on morphological characters.
During a botanical survey to Bomi County, Tibet, China in November 2017, some plants of Bulbophyllum with young inflorescence were transferred to Xishuangbanna Tropical Botanical Garden (XTBG), and flowered on Dec. 18, 2017.
​ 
XTBG researchers carried out morphological studies and consulted a large amount of literature. They confirmed that the flowering Bulbophyllum plant is new to science. They named it as Bulbophyllum yarlungzangboense to refer to Yarlungzangbo Grand Canyon where it was discovered. 

Bulbophyllum yarlungzangboense grows epiphytic on trees or mossy rocks near to the riverside in Yarlungzangbo Grand Canyon, at elevations about 1700–2100 m. It flowers from November to December.

Picture
The type plant of Bulbophyllum betchei F.Muell. (sect. Polymeres) was collected by the German orchid collector Ernst BETCHE on Samoa and this species was named in his honour. The small epiphyte has a patent to pendolous, sparsely branched rhozome, which is up to 10 cm long. The red-brown striped flowers appear from the base of the pseudobulbs and are about 1.2 cm across the widest point. It is a most attractive plant. This is a widely distributed species, which has been found in Java, Borneo, Sulawesi, New Guinea, the Carolines, Vanuatu, New Caledonia, Fiji and Samoa. In the Philippines it has been found on the island of Leyte and Samar, where it grows as an epiphyte at elevations of about 600 m.
Picture
Bulbophyllum canlaonense Ames (sect. Minutissima) was described from plants collected on the active vocano, Mount Kanlaon, which is on the island of Negros. It was named after this volcano. There is considerable variation in the colouration of this species. The first author has seen flowers which are golden brown and others which are claret red. It is endemic to the Philippines and has been recorded from Benguet province on Luzon, the islands of Leyte, Negros, Panay and Samar in the Visayan Sea, as well as Bukidnon and Misamis on Mindanao, where it grows as an epiphyte on the branches and trunks of trees at elevations of between 1300 and 2300 m.
Picture
This exquisite (= lat. exquisitus) miniature plant has beautiful, large flowers about 1.5 cm across. Bulbophyllum exquisitum Ames (sect. Macrocaulia) is endemic to the Philippines and has been recorded from the Mountain province; the island of Leyte in the Visayan Sea; and the province of Misamis Oriental on Mindanao, where it grows as an epiphyte at elevations above 2000 m.
Picture
Bulbophyllum lipense Ames (sect. Hybochilus) appears to be closely related to Bulbophyllum colubrimodum, but differs in the broader, shorter floral segments. The specific epithet refers to Mount Lipa in Bukidnon province, where the type specimens  were collected. It is endemic to the Philippines and is only known from the provinces of Bukidnon and Misamis on the island of Mindanao where it grows as an epiphyte at elevations of around 1200 m.
Picture
Bulbophyllum ovalifolium (Blume) Lindl. (sect. Macrocaulia), with small pseudobulbs and more or less oval leaves (= lat. ovalifolius) is a most delightful species with its brightly coloured blooms up to 2 cm diameter. The colour is extremly variable ranging from bright yellow, to orange, and dull red. The hair like inflorescence is about 6 cm long and carries only a single flower, which stands well above the foliage. It is a widley spread species and it has been recorded from Thailand, Peninsular Malaysia, Sumatra, Java, Sulawesi (Celebes), and Borneo. In the Philippines, it is known from the island of Biliran; the provinces of northern Mindanao; and Palawan, where it grows as an epiphyte at elevations over 500 m.
Picture
Bulbophyllum restrepia (Ridl.) Ridl. (sect. Hoplandra) was first (1893) described as Cirrhopetalum restrepia, which stretches definitions of that genus to the limit. The epiphet makes reference to the similarity with flowers of the genus Restrepia. It is a widely distributed species, which has been recorded from Peninsular Malaysia, Sumatra, Borneo Maluku (the Moluccas) and New Guinea. In the Philippines it is known from the island of Samar; and the north on Mindanao, where it grows asa an epiphyte at elevations of about 300 m.

Abstract: The Genus Bulbophyllum is represented, in the Philippines, by at least 130 species. Many of the species have large flowers, but there are just as many that have small, but still very showy blooms. It is these miniatures which we wish to introduce here.
Picture
Bulbophyllum boosii J.J.Verm. & Kindler (sect. Polymeres) has recently been found on northern Mindanao and only named three years ago. The origin of the type plant is not known, but Mr. Ronny BOOS shares a photo of a different plant from Samar. This species was named in his honour. The whole plant is only 4 - 5 cm tall. The blooms are 1.5 cm large and a most attractive yellow in colour, the labellum is in the front area almost black, which makes a very nice contrast. There is a form of this species, which occurs on the island of Sibuyan that has black petals. The plants from Samar were found at about 600 m elevation, whereas those from northern Mindanao come from about 1200 m.
Picture
Bulbophyllum colubrimodum Ames (sect. Hybochilus) is endemic to the Philippines and has been recorded from the islands of Mindoro and Leyte, the provinces of Misamis and Zamboanga on Mindanao. The specific epithet refers to the apex of the labellum, which in some positions, resembles the head of a snake, about to strike. This is also a very variable species in its colouration. The flowers are non-resupinate (having the labellum uppermost). It grows as an epiphyte at elevations of about 600 m.
Picture
Bulbophyllum halconense Ames (sect. Minutissima) is named after Mount Halcon, on the Island of Mindoro, which is reputably one of the most treacherous mountains in the Philippines. The plant has conical pseudobulbs that have a wrinkled appearance. The flowers are about 3 cm in height. It is endemic to the Philippines and has also been recorded from Zambales province on Luzon; and Mount Halcon in the north of the island of Mindoro, where it grows as an epiphyte on the branches and trunks of trees at elevations of between 1500 and 2500 m.
Picture
Bulbophyllum mindorense Ames (sect. Minutissima) is barely 3 cm tall, but it carries flowers, which are more than 2 cm in diameter. The inflorescence extends well past the foliage and can appear from either the base of the pseudobulb or along the rhizome. It has been recored from southern Luzon, the islands of Mindoro (named after this island), Leyte and the province of Misamis Oriental on Mindanao.
Picture
Bulbophyllum peramoenum Ames (sect. Minutissima) is a most delightful species (= lat. peramoenus), with its whisker-like petals and amazing labellum, the tip of which has the appearance of insect eggs, or white aphids. When the first author first saw the tip of the labellum he thought it had been nibbled on by a snail or slug. It is endemic to the Philippines and has been found on the islands of Mindoro and Leyte, the provinces of Bukidnon, Misamis Oriental and Zamboanga on the island of Mindanao, where it grows as an epiphyte at elevations of about 1200 m.
Picture
Bulbophyllum rubrolingue Cootes et Boos (sect. Polymeres) is a most beautiful species with a large flower about 5 cm in height. The blooms open widley and are most pleasantly coloured; the tongue-shaped lip is red (lat. rubrolingua). It is endemic to the Philippines and is only known from the island of Leyte in the Visayan Sea, where it grows in rain forest, at elevations of around 600 m.

Bulbophyllum chrysolabium     Photos by the authors
Abstract: Bulbophyllum chrysolabium, a new species belonging to section Racemosae from Yunnan, China is described and illustrated. The species is related to B. orientale and B. morphologorum, but differs by having the following set of characters: obliquely broadly-based triangular petals with a long filiform apex; lip densely glandular papillose and conspicuously ciliolate along margins; lip auricles well developed, narrowly falcate, tapering to a long sharp point at the apex; stelidia subulate and twisted inwards, slightly exceeding operculum. The conservation status of B. chrysolabium is assessed and taxonomic notes are provided.
Bulbophyllum chrysolabium is distinguished from all known congeners by having the following unique combination of features: obliquely broadly-based triangular petals with a long filiform apex; lip densely glandular papillose on both sides and conspicuously ciliolate along margins; lip auricles well developed, narrowly falcate, tapering to a long sharp point at the apex; stelidia subulate and twisted inwards, slightly exceeding operculum.
 Taxonomic notes:   Bulbophyllum chrysolabium appears to be related to B. orientale Seidenf. (Seidenfaden 1979: 138), especially in narrowly falcate lip auricles and twisted stelidia, but differs in distinctly longer floral bracts (almost twice as long as the pedicel and ovary); petals with long filiform apices, a rather smaller lip (ca. 2.8 mm long), significantly glandular-papillose and ciliolate at margins; stelidia slightly exceeding operculum and distinctly longer than column. With respect to filiform petals, B. chrysolabium is also superficially similar to B. morphologorum Kräenzl. (1908: 89), however, the latter have a fat, conical protuberance or callus on the front of the column near its base and scape much longer than rachis. In addition, it has subulate, not twisted stelidia, considerably longer than operculum; lip auricles not falcate, but rather obtuse at the apex. A detailed morphological comparison between B. chrysolabium and its allied species is presented in Table 1.

Bulbophyllum pyrrosifolium     Photo: Miguel D. De Leon
Abstract: A new Bulbophyllum species, Bulbophyllum pyrrosifolium (sect. Brachystachyae), and a new Dendrobium species are proposed from the province Bukidnon, Mindanao and a new Dendrobium species from the island province of Palawan is also proposed.

The unusual and attractive foliage of Bulbophyllum pyrrosifolium is similar to the Bornean species Bulbophyllum botryophorum Ridley. Unlike the latter, the leaves of B. pyrrosifolium are ermarginate and do not lay on the substrat. The pseudobulbs of B. pyrrosifolium are clustered on  the rhizome whilst those of Bulbophyllum botryophorum are spaced at intervals approximately 5 - 9 millimeters; also B. pyrrosifolium has a few-flowered inflorescence whilst that of Bulbophyllum botryophorum is a many-flowered, compact inflorescence.

Bulbophyllum pyrrosifolium is only known from Bukidnon on Mindanao. It grows as an epiphytes, in partial shade in mossy dipterocarp forest, at 1,600 metres above sea level.

Bulbophyllum adolinae     Photos: André Schuiteman
Abstract: Two new species of Bulbophyllum are described here as Bulbophyllum irianae (sect. Hoplandra) and Bulbophyllum adolinae (sect. Peltopus)
Bulbophyllum irianae ist most similar to Bulbophyllum obovatifolium J.J.Sm., but differs in the apex of the median sepal which is a long, solid, terete, subulate awl c. 0.8 cm long that is adaxially in the lower half flat, has no crest or keel, and narrows continuously and gradually into very thin, narrowly acute tip (versus median sepal keeled, acute, concave, the top half in the middle conduplicate, laterally compressed); the lip from above slender narrowly triangular with a narrowly acute apex and a smooth upper surface without ornamentation (versus lip from above tongue-shaped with an obtuse apex and a channeled upper side with two ribs and a low small rib in the middle); lateral sepals c. 8.2 cm long and 6 times twisted around each-other (versus lateral sepals c 4.5 cm long and not twisted).

Bulbophyllum harposepalum Schltr. is often treated as a synonym of B. obovatifolium. It differs from B. irianae in the much smaller, not twisted sepals, the broader and obtuse lip with a median depression and obtuse apex, and in the median sepal which is towards the top conduplicate-compressed and keel-like, rather blunt, not gradually tapering.

It grows as a crown epiphyte in slightly disturbed rain forest with trees up to c. 45 m tall, with much undergrowth. Terrain undulating to steep. Elevation c. 300 m. Flowering in the wild in February.

Bulbophyllum adolinae differs from B. octarrhenipetalum J.J.Sm. in the terminal callus of the column-foot, which is bilobed, with one lobe pointing upwards and one, almost equally large, lobe pointing downwards (versus only one upwards-pointing callus in B. octarrhenipetalum); rostellum minute, erect (versus rostellum distinctly protruding, porrect); petals only 0.6 mm wide (versus petals 0.9 - 2.5 mm wide), sepals with glabrous, not ciliate, margins, and the bright yellow lip (versus lip white or purple).

A thorough revision of Bulbophyllum sect. Peltopus was published by J.J. Vermeulen (1993). Among the 32 species recognized by him, only B. octarrhenipetalum J.J.Sm. is similar enough that a careful comparison is required to tell them apart. Vermeulen's view, B. octarrhenipetalum is an extraordinarily variable species. Field studies are needed in order to establish if the variation is truly infraspecific and not caused by hybridization. Bulbophyllum adolinae was discovered in 2014 during a joint field trip in the Arfak Mountains, West Papua Province, Indonesia, carried out by staff of the Royal Botanic Gardens, Kew (André Schuiteman and Marie Briggs) and the Universitas of Papua.

It is a Epiphyte on moss-covered tree trunks in montane forest. Elevation 1970 m. Flowering observed in July.

Abstract: Three taxa, Bulbophyllum cariniflorum var. orlovii (sect. Pleiophyllum), Bulbophyllum sonii (sect. Anisopetalon) and Bulbophyllum ustulata (sect. Brachystachya) are described as new for science. All of these novelties are local endemics of Vietnam. Additionally, four species, Bulbophyllum flavescens (sect. Aphanobulbon), Bulbophyllum ovatum (sect. Desmosanthes), Bulbophyllum physocoryphum (sect. Macrocaulia) and Bulbophyllum wendlandianum (sect. Cirrhopetalum) are recorded for the flora of Vietnam for the first time. These species are endemic of the Indochinese Peninsula in a broad sense, except for Bulbophyllum flavescens having wide distribution in western Malesia. Data on ecology, phenology, distribution, brief relevant taxonomic notes, as well as colour photographs and line drawings of the type and voucher specimens are provided for all reported taxa. Lectotypification is provided for Bulbophyllum wendlandianum.
Bulbophyllum cariniflorum has for a long time been taxonomically placed into a rather formal artificial group of deviated Bulbophyllum species known as a B. section Pleiophyllum (Seidenfaden, 1979; Pearce & Cribb, 2002; Chen et al. 2009). All these species have more or less similar 2-leaved pseudobulbs that is quite unusual for the genus. Meanwhile, species of this section show hardly close relations. At least B. cariniflorum and its close allies, such as B. triste Reichenbach (1861: 253) and B. viridiflorum (Hooker 1890: 779) Schlechter (1910: 108) look much more close to some members of B. sect. Anisopetalon (Hooker 1825: tab. 149) Lindley (1846: 181) according to their floral morphology. Our plant undoubtedly belongs to this group and most close to B. cariniflorum distributed mainly in the Himalayas. However, it distinctly differs from other known specimens of this species in such morphological details as large, slightly flattened, often 3-leaved pseudobulbs (1.8)2.5–3.0(3.4) cm tall and wide (vs. 2-leaved ovoid pseudobulbs 1–1.5 cm tall), large leaves (10)12–18(20) cm long (vs. 12–15 cm long), long panicle (2.0)3.0–5.0(6.5) cm long (vs. 2–3 cm long), narrowly ovate floral bracts (vs. narrowly lanceolate) and falcate, back curved stelidia (vs. straight erect subulate stelidia). Described variety belongs to species newly recorded in the flora of Vietnam. The discovery of our plant in Vietnam essentially extends the known species distribution area to the East and represents its first record in eastern Indochina.
Bulbophyllum sonii belongs to the rather formal group of species with simple lip (having no auricles or any other ornamentation) belonging to B. sect. Anisopetalon (= Racemosae). Bulbophyllum brevispicatum Z.H.Tsi & S.C.Chen (1994: 555) and B. triviale Seidenfaden (1979: 111) are probably most close to our plant. Some species with auriculate lip, e.g. B. allenkerrii Seidenfaden (1979: 112) and B. bittnerianum Schleichter (1910: 108), also show certain similarity with the new species. Our plant strikingly differs from all more or less similar known species in its dwarf habit, pendulous inflorescence, twice smaller flowers and curious setose hairiness on abaxial surface of sepals consisting of white dense papillous hairs.
Bulbophyllum ustulata belongs to B. sect. Brachystachya (= B. sect. Globiceps ) and is allied to some Himalayan taxa, namely Bulbophyllum conchiferum Reichenbach (1861: 253), B. cylindraceum Lindley (1830: 53) and B. khasyanum Griffith (1851: 284). Similarly, to these species, our plant possesses very small pseudobulbs, elongate, nodding, spadix-like, dense inflorescence with small sessile, flattened, overlapping flowers densely appressed to rather fleshy rachis. Meanwhile, the discovered plant cannot be identified as any of the above-mentioned species. Among the mentioned species, the new species may be most close to B. conchiferum undeservedly regarded as a synonym of B. khasyanum (Pearce & Cribb 2002), which type specimen has short, almost head-like spike. Inflorescence and flowers of B. ustulata fits well the excellent analytical drawing presented on type herbarium specimen of B. conchiferum stored at K [K000894441] in elongate rachis, dense, shell-like sessile flowers, acuminate, revolute apex of median sepal, acuminate recurved petals, 2-keeled lip and long stelidia. However, our plant differs from B. conchiferum in large involucral sheathing bract at the base of rachis (a feature that is also observed in typical samples of B. cylindraceum), glandular hairy median sepal, straight stelidia (vs. stelidia at the middle upward bent) and fleshy inflated margin of stigma close to the base of column foot. The new species was collected in a single location near summit of Phu Xai Lai Leng Mountain very close to the Laotian border.
The discovery of Bulbophyllum flavescens (Blume) Lindl. previously believed to be a Malesian endemic in northern Vietnam is remarkable and unexpected. The newly discovered quite isolated location expands known distribution area of this species almost 2000 km in northwestern direction and illustrates well the connection of Malesian flora with marginal tropical floras of mainland Asia. At the same time, the discovered Indochinese population certainly possesses relict nature and surely represents ancient geographical isolation resulted in some morphological divergence. The studied Vietnamese plants well differ from quite variable specimens described in details from the main area of the species distribution (Comber 1990, 2001, Seidenfaden & Wood 1992) in larger flowers with sepals 13–15 mm long (vs. sepals 6–8 mm long in Peninsular Malaysia and 10–11 mm long in Sumatra and Java) and narrowly lanceolate leaves 1.6–2 cm wide (vs. broadly lanceolate leaves 2–3 mm wide). In this connection, our plants probably represent a separate variety and need additional studies. 
The specimens of Bulbophyllum ovatum Seidenfaden look identical with the species described from southern Thailand (Seidenfaden 1979) and initially regarded as local endemic of the Malay Peninsula. The population of this species discovered in northern Vietnam is distant from locus classicus at more than 1200 km in NNE direction.

Recent discovery of Bulbophyllum physocoryphum Seidenfaden in southern Vietnam and in Cambodia (Averyanov et al. 2016a) provides evidence of its much border distribution in southern Indochina than it was expected before.

The present discovery extends known distribution area of Bulbophyllum wendlandianum to almost 1000 km in SE direction and adds one more eastern Himalayan species to the flora of Vietnam. There are few doubts that this rare species may also be found in northern Laos. This species may be regarded as a true endemic of northern Indochina. Type herbarium material of B. wendlandianum was most likely destroyed or lost: “I do not know if a type specimen of Kränzlin’s plant exists, ...” (Seidenfaden 1972). Hence, the drawing which was probably based on the original material is designated here as a lectotype.
Note(b.info): Following G.A. Fischer & Vermeuelen 2014 and Vermeulen et al. 2014, B. cariniflorum v. orlovii belogns to sect. Lemniscata, B. sonii to sect. Racemosae, B. flavescens to sect. Stachysanthes and B. wendlandianum to sect. Cirrhopetaloides.

Bulbophyllum aberrans   Photos by the author
Summary: Bulbophyllum aberrans Schltr. (Orchidaceae), a miniature-sized epiphytic orchid belonging to the section Oxysepala of Bulbophyllum and so far reported from Malaya, Borneo and Sulawesi is now reported here as an addition to the orchid flora of India from the Andaman and Nicobar Islands. A brief note on its taxonomy and distribution is presented along with its diagnostic characters for easy identification. 

(...) During floristic explorations in Great Nicobar Island a few specimens belonging to the genus Bulbophyllum were collected which on critical study was identified as Bulbophyllum aberrans
Schltr. A thorough scrutiny of literature (Sinha 1999, Misra 2007, Pandey and Diwakar 2008, Karthigeyan et al. 2014, Murugan et al. 2016) revealed that this species was hitherto not recorded from the Andaman and Nicobar Islands or mainland India. Hence, in the resent treatment, this species is reported as a new addition to the orchid flora of the Andaman and Nicobar Islands and therefore India. Brief description along with illustration and photographs is provided to facilitate easy recognition of the species.

Abstract: Two new Bulbophyllum species from Peninsular Malaysia are dedscribed and  llustrated: Bulbophyllum jayjayveeanum (sect. Rhinanthera) and Bulbophyllum nazrii (sect. Monanthaparva).
Bulbophyllum jayjayveeanum  is unique in the section in the ovary being much longer than the pedicel, and the lateral sepal margins being erose near apex. It also differs from Bulbophyllum turpe J. J. VERM. et P. O’BYRNE in having a very crowded rachis, lateral sepals less than 7 mm long, a column with a small rounded tooth on each margin, and a column-foot with a rounded apex that lacks a raised tooth.
Bulbophyllum nazrii differs from Bulbophyllum comberi J. J. VERM. in having a retrorse uncinate tooth on the column wing, a stigma with a protruding basal margin, a lip that lacks cilia and has irregularly pectinate margins, and broad-lanceolate petals.
