7994B7F386C85EA98D7DBD165ADF0B21.taxon	diagnosis	Diagnosis. Similar to Bulbophyllum pyroglossum Schuit. & de Vogel because of the hinged lip and the hair-like appendages on the surface of the lip, but in that species the appendages are about four times longer, and they are discrete, subulate projections arranged in rows, not forming densely lacerate-fimbriate keels as in Bulbophyllum leucoglossum. Moreover, Bulbophyllum leucoglossum has two lamellae on the abaxial (concave) side of the lip; these are lacking in Bulbophyllum pyroglossum. The latter also has much broader and shorter petals, and an orange instead of a white lip.	en	Juswara, Lina, Schuiteman, Andre, Droissart, Vincent (2016): Four new orchid species from the Lengguru fold belt, West Papua, Indonesia.

4039ABBD7BE65B9C8AE3D7E40C8243C3.taxon	diagnosis	Diagnosis. The short and dense inflorescences with small, purple flowers and green-tipped, long-apiculate sepals resemble those of Dendrobium purpureum Roxb., a lowland species from Maluku and Sulawesi. However, the plant habit of the latter is completely different, as Dendrobium purpureum has robust, many-leaved, cane-like, tufted stems up to more than 50 cm long. Vegetatively, Dendrobium centrosepalum is more similar to Dendrobium aurantiroseum P. Royen ex T. M. Reeve from New Guinea, which also has unifoliate pseudobulbs on a creeping rhizome. However, the latter is a species from high elevations (2100 - 3350 m) with pink flowers that are about twice as large, while the sepals are not apiculate; in addition, the cross-ridge on the lip is situated below the middle in Dendrobium aurantiroseum and above the middle in Dendrobium centrosepalum.	en	Juswara, Lina, Schuiteman, Andre, Droissart, Vincent (2016): Four new orchid species from the Lengguru fold belt, West Papua, Indonesia.
