'''Stellilabium''' is a small genus in the orchid family ([[Orchidaceae]]).

The name is derived from the Latin words ''stella'' (star) and ''labium'' (lip), referring to the star-like bristles on the [[labellum|lip]].

This seldom-seen, neotropical genus occurs from Costa Rica to Venezuela and Western South America as [[epiphyte]]s on twigs of [[guave]] trees in extremely wet tropical forest habitats at elevation between 1400-2500 m.

They are characterized by a short [[Plant stem|stem]] with extensive [[root]]s, and [[Leaf|leaves]] that are folded lengthwise. The lateral inflorescence gives a [[raceme]] or a [[panicle]] with few to many miniature to small (from a few mm. to 1 cm), resupinate [[flower]]s. The distinct [[column]] has an elongate, rostellar beak. There are four [[pollinium|pollinia]].

''Stellilabium jostii'' practices [[pollination]] by deceit by imitating the genitalia of a female fly. The hairs are perfectly engineered to stop the airflow of the wings of the fly, so as to stick a maximum of pollen on the fly.

This genus has been split in the past from the genus Telipogon on morphological grounds (smaller flowers than in ''Telipogon''). But, according to N.H. Williams of the University of Florida, this genus should be remerged with the genus ''[[Telipogon]]''. He came to this conclusion on genetic grounds (Botany 2005 conference, Austin, Texas)
