Common Name Herrera's Pterichis [Costa Rican Collector of the type current]
Flower Size .48" [1.48 cm]
Found in Puntarenas province of Costa Rica in cloud forests at elevations around 3200 meters as a small to just medium sized, cold growing terrestrial with a basal, linear-lanceolate, acute, long petiolate base leaf that blooms in the fall on an erect, terminal, peduncle to 10.8 [27 cm] long, provided with 4, glabrous, tubular, pubescent in the upper part sheaths, rachis 1.08 to 2" [2.7 to 5 cm] long, pubescent, subdensely 4 to 10 flowered inflorescence with pubescent, narrowly ovate, subobtuse, a bit shorter than the ovary floral bracts and carrying flowers with a greenish yellow lip.
"This species resembles P. habenarioides (F.Lehm. & Kraenzl.) Schltr. and P. triloba (Lindl.) Schltr.. From the latter species P. herrerae is easily distinguished by the cordate lip base (vs. truncate in P. triloba), the 5-veined lip disc (vs. 7-veined) and presence of numerous (over 30 in total) knob-like projections along the lip margins (vs. 8?10 projections on each side). The floral bracts of P. habenarioides are glabrous, its dorsal sepal is ovate-lanceolate (vs. lanceolate in P. herrerae), the petals are obovate-lanceolate, not unguiculate (vs. linear-lanceolate above, unguiculate basally), and the lip is transversely triangular-elliptic in outline (vs. cordate in P. herrerae). Another similar species is the South American P. diuris Rchb. f., which has petals free from dorsal sepal, the lip base is truncate and disc lacks any knob-like projections." Kolanowska 2014
