Cirrhopetalum, abbreviated as Cirr in hortcultural trade, is a genus of epiphyte orchids (family Orchidaceae, subfamily Epidendroideae). This genus is very closely related to Bulbophyllum and its members have been until recently considered to be in the genus Bulbophyllum. The taxon name comes from Latin cirrus (fringe) and Greek petalon (petal), hence meaning fringed-petaled.
Plants in this genus are usually small plants with creeping rhizomes
. Features that distinguish this genus from Bulbophyllum
- The dorsal sepal of Cirrhopetalum is much smaller than the usually inrolled lateral sepal which has adnate margins.
- There is generally an umbellate inflorescence which can be upright, pendulous or arching.
- The pseudobulbs are conical-shaped and obscurely angled with a single spoon-like leaf atop each pseudobulb.
