Description

This genus was first described in 2001 by D. L. Jones and M. A. Clements,^[1] and "... segregated from Bulbophyllum based on tiny pseudobulbs with a small internal cavity near the apex, a single tiny bract-like leaf on each pseudobulb, single-flowered inflorescence arising from the base of a pseudobulb and small flowers with a warty ovary." They grow in many habitats ranging from very exposed to relatively sheltered. They are pollinated by insects and are fairly easy to cultivate on a hard slab with reasonably bright light, high humidity and good ventilation, and regular watering all year.^[2]

Type species: Bulbophyllum minutissimum F.Muell.

The scientific name has been derived from the Neo-Latin word onco, from Greek onkos (barbed hook); and phyllum ("one having (such) leaves or leaflike parts") from Neo-Latin phyllum from Greek phyllon (leaf).^[3]

Conservation status

O. globuliforme is considered "vulnerable", but O. minutissimum is widely distributed and common in Queensland and New South Wales from the Blackdown Tableland to Bateman's Bay.
