Cyrtochilum pusillum (C.Schweinf.) Dalström 2001 TYPE Drawing by Schweinfurth

Common Name The Small Flowered Cyrtochilum

Flower Size .16" [4 mm]

Found in Peru in cloud forests at elevations around 2800 meters as a small sized, cold growing epiphyte with an ascending bracteate rhizome giving rise to basally thickened, attenuate above pseudobulbs enveloped almost completely by linear, imbricating foliaceous sheaths and carrying a single, apical, linear, conduplicate towards the base leaves that blooms in the summer on an axillary, slender, suberect, linear, racemose, to 6" [15 cm] long, 3 to 9 flowered inflorescence carrying small, pure white flowers.

This species differs from C vasquezii by having pure white flowers and less connate lateral sepals, floral bracts longer than the ovary and a thicker column. C vasquezii has nearly completely connate lateral sepals, shorter than the ovary floral bracts, a more slender column and magenta marked flowers.
