Common Name The Acuminate Pterichis

Flower Size .2" [5 mm]

Found in Colombia, Ecuador and Peru at elevations of 2500 to 3600 meters as a small to large sized, cold growing terrestrial with a single, elliptic, acute, tapering to a conduplicate, elongate petiolate base leaf that blooms on an erect, puberulent, 8 to 28" [20 to 70 cm] overall long, rachis 2 to 12" [5 to 30 cm] long, cylindric, loosely many flowered inflorescence with ovate-lanceolate, pubescent, acute to subacuminate floral bracts.

"This species is considered by some authors (Schweinfurth, 1941,1958) as conspeci?c with Pterichis galeata, which is easily distinguished from P. acuminata by long-clawed petals being longer than dorsal sepal (by 10–20%) and auriculate lip basal part. In the somewhat similar P. meirax the petals are oblong-lanceolate, with some hairs on the margin and the lip basal part is transversely elliptic." Kolanowska 2021
