Common Name The White-Green Cyrtochilum

Flower Size .8" [2 cm]

Found Santander and Boyacá departments of Colombia on the Eastern Cordillera of the Andes in pastures near relict forests at elevations of 2300 to 2600 meters as a small to medium sized, cold growing epiphyte with ovoid and slightly flattened, glossy green with brown markings at the base when exposed to sun, becoming orange-brown with age, bifoliate pseudobulbs surrounded basally by 3 to 4 foliaceous and deciduous, distichous sheaths and carrying conduplicate, sessile, obovate-ligulate, obtuse leaves that blooms in the earlier summer on an axillary, from the uppermost sheath, an erect to arching panicle with multiple few-flowered side-branches, to 48" [120 cm] long, many flowered inflorescence with appressed, scale-like bracts.

"Cyrtochilum albovirens with its white and yellow-green flowers is easily recognized by the rhomboid pink lip, basally yellow and apically white callus that terminates in a pair of parallel digitate keels. The new species is easily distinguished in a fresh state due to the combination of yellow-green sepals and the bi-colored lip callus. In a dried state, it may superficially resemble other small-flowered Cyrtochilum species, such as Cyrtochilum confertum (Rchb.f.) Dalström, Cyrtochilum distans (Rchb.f.) Kraenzl., Cyrtochilum funis (F.Lehm. & Kraenzl.) Kraenzl., Cyrtochilum longifolium (Lindl.) Kraenzl., and Cyrtochilum myanthum (Lindl.) Kraenzl., but can be distinguished from all by the raised and humplike base of the callus, which extends in a rather straight direction down from the column in a ca. 45º angle." Dalstrom 2018
