Common Name The Keeled Microchilus [refers to the three keeled lip unique to genus]

Flower Size .04" [1 mm]

Found in Cauca department of Colombia in primary forest or wet forest on sides of a canyon with clearings at elevations around 2200 to 2300 meters as a small sized, cold growing terrestrial with an erect, terete stem carrying 6 to 7, obliquely ovate-lanceolate, subacuminate, petiolate base leaves that blooms in the late spring on an erect, terminal, pubescent, 15.72 to 24.6" [38.8 to 55.9 cm] long overall, peduncle 11.92 to 15.84" [29.8 to 39.6 cm] long, provided with 4 to 5, scattered sheathing bracts, rachis 2.72 to 6.52" [6.8 to 16.3 cm] long, densely many flowered inflorescence with lanceolate to ovate-lanceolate, acute, shorter to longer than the ovary floral bracts and carrying externally pubescent flowers of unknown colors.

"This species appears to be related to its Colombian congener Microchilus globosus but it differs from that in having flowers with a tricarinate (vs. ecarinate) labellum hypochile and obtuse (not truncate) epichile lobules. Microchilus carinatus is unique in the genus because it is the only taxon with three keels on the lip." Ormerod 2007
