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.
