About Ancistrochilus
What is Ancistrochilus?
Ancistrochilus is a genus of orchids belonging to the family Orchidaceae, notable for containing only two recognized species. These orchids are characterized by their sympodial growth habit and their presence in tropical regions of Africa. The genus is distinguished by its attractive and fragrant flowers, which have a unique lip structure.
Description and Habitat
These orchids are described as cool to hot growing, typically found in tropical West Africa, extending eastward to Tanzania and Uganda. They grow epiphytically on tree trunks and large branches, usually at elevations between 500 and 1100 meters. The plants feature characteristic conical or pyriform pseudobulbs that are sympodial. Each pseudobulb supports two to three broad, acute, lanceolate leaves, which are shed after the plant's growth period slows down.
Flowers
Ancistrochilus orchids produce a pubescent inflorescence from the base of mature, leafless pseudobulbs, bearing three to four large and attractive flowers. Each flower measures approximately 8 cm across and is notably fragrant. The petals and sepals are typically a dark rose-pink color, while the three-lobed lip is a vibrant magenta. A distinctive feature of the lip is its elongated, narrow, and curved projection, which gives the genus its name.
Taxonomy
The scientific name Ancistrochilus is derived from two Greek words: 'ankistron,' meaning 'hook,' and 'cheilos,' meaning 'lip.' This nomenclature directly references the hooked or curved form of the orchid's lip, a key identifying characteristic.
