Ancistrochilus

Ancistrocilus rothschildianus
Ancistrochilus thomsonianus

Ancistrochilus Rolfe 1897, is an genus with only two species from the orchid family (Orchidaceae), subfamily Epidendroideae, tribe Arethuseae, subtribe Bletiinae

The name is derived from the Greek words ankistron (hook) and cheilos, (lip), referring to the form of the lip.

These two species are cool to hot growing orchids, found from tropical West Africa to Tanzania and Uganda. They grow on tree trunks and large branches at elevations between 500 to 1100 m.

These are sympodial epiphytic plants with wide, characteristic conical or pyriform pseudobulbs, carrying two to three broad, acute, lanceolate leaves. These leaves are shed after growth has slowed down.

Three to four large and attractive, fragrant flowers, 8 cm across, then appear from the base of the mature leafless pseudobulb in a pubescent inflorescence. The petals and sepals are dark-colored, rose pink . The three-lobed lip is magenta. It ends in an elongated, narrow, curved projection.
