Part Sun Cool Cold Fall Winter Spring

Common Name The Mouse-Like Cyrtochilum [refers to the small flowers]

Flower Size .4" [1 cm]

Found in Venezuela, Colombia and Ecuador in montane cloud forests at elevations around 1700 to 2500 meters as a medium sized, cool to cold growing terrestrial or epiphyte with clustered, slightly compressed, wrinkled pseudobulbs enveloped basally by several pairs of distichous, imbricating, leaf-bearing sheaths and carrying 1 to 3, apical, strap-shaped, acute, keeled, conduplicate below into the base leaves that blooms in the fall, winter and spring on an axillary, somewhat erect, to 18" [45 cm] long overall, shortly paniculate, 3 to 6 flowers per branch, many flowered inflorescence arising on a mature pseudobulb with all the flowers in the apical 1/3 of the scape.

This species, C diodon, C porrigens and C umbonatum are all very similar and may all be in one variable species complex but I have kept them separate for now.
