TYPE Drawing by © Paul Ormerod and Harvard Pap. Bot. 9: 401 fig 10 Ormerod 2005

Common Name The Constricted Microchilus

Flower Size .12" [3 mm]

Found in the Valle de Cauca department of Colombia, Peru and Brazil in cloud forests at elevations around 300 to 600 meters as a small sized, hot to warm growing terrestrial with a erect, terete stem carrying 8, ovate-lanceolate to lanceolate, acute, petiolate base leaves that blooms in the summer on an erect, terminal, pubescent, 7.6" [19 cm] long overall, peduncle 3.44" [8.6 cm] long, rachis 4.16" [10.4 cm] long, sublaxly flowered inflorescence with ovate-lanceolate, acute, as long as the ovary floral bracts and carrying externally pubescent, white colored flowers.

"This species resembles Microchilus arietinus , but it differs from that in its rectangular-subpandurate labellum hypochile. In M. arietinus , the hypochile is subquadrate in the lower half and then it gradually narrows toward the epichile in its upper half. Another feature that may possibly differentiate M. constrictus from M. arietinus is the sub- cuneate shape of the stigmatic area. In M. arietinus, the stigmatic area is shallowly V-shaped. However, better material of M. constrictus is needed to be certain of the shape of the stigmatic area because the column was quite compressed in the type specimen." Ormerod 2005
