Common Name Chaillu's Cyrtochis {French orchid Collector in Madagascar 1900's]

Flower Size 3" [7.5 cm] spur 6" [15 cm]

Found in central to west Africa as a medium to large sized, cool growing epiphyte in tropical forests at elevations of 1150 to 1250 meters where it benefits from a cooler drier winter and has elongated stems carrying ligulate to oblanceolate leaves and blooms on a to 10" [25 cm] long, several flowered [7 to 10], racemose, axillary inflorescence giving rise to waxy, fragrant, white turning apricot flowers occuring in the winter.

Often said to be the same as C letouzeyi but differs most distinctly in having an axillary inflorescence instead of from the stem.
