Common Name The Long Inflorescence Microchilus

Flower Size .08" [2 mm]

Found in Valle de Cauca department of Colombia at elevations around 2000 meters as a large sized, cool to cold growing terrestrial with an erect, substrict, terete, glabrous, leafy stem carrying 6 to 7, erect-patent, obliquely elliptic, acuminate, glabrous, cuneate below into the petiolate base leaves that blooms on an erect, terminal, strict, few sheathed, glandular-pilose, peduncle to 10" [25 cm] long, rachis to 12" [30 cm] long, laxly many flowered inflorescence with suberect, lanceolate, acuminate, half as long as the ovary floral bracts and carrying small flowers with densely glandular sepals.

"Similar to Microchilus hetaerioides but differs in the lax inflorescence, the smaller flowers and the different lip form. The unique character to this species is the oblong to oblong-elliptic hypochile that is slightly concave at the base and has undulate margins in the upper half. The lip shape of this species is similar to Microchilus ecuadorensis but it has a narrowly cylindrical spur that is .16" [4 mm] long." Szlachetko & Kolanowska 2017
