Common Name or Meaning Guillermo's Epidendrum [Dr Guillermo Misas Urreta Colombia orchid collector and orchid enthusiast current]

Flower Size 1.6" [4 cm]

Found in Choco' department of Colombia in montane forests at elevations around 400 to 500 meters as a large sized, hot growing epiphyte with erect, simple, cane-like, laterally compressed, thin, straight, ancipitose stems carrying 8, throughout the apical half of the stem, alternate, articulate, coriaceous, narrowly obovate-elliptic, acute, the underside tinged wine-red, margin entire, spreading leaves that blooms in the late winter and early spring on a terminal, racemose (producing successive, lax, few-flowered racemes from the same peduncle and thus pluri-racemose), straight, laterally compressed, thin, slightly flexuous, 5.2 to 6.4" [13 to 16 cm] long including the 4" [10 cm] long peduncle provided with 3 to 4, scarious, tubular, acute, partly imbricating bracts, rachis laterally compressed, thin, slightly flexuous, simultaneously 4 to 10 flowered inflorescence with shorter than the ovary, triangular, acuminate, amplexicaul floral bracts.

"Epidendrum guillermoi belongs to the GROUP Pseudepidendrum which is characterized by caespitose plants, cane-like stems, acute to acuminate leaves, usually apical inflorescence, the mostly filiform petals and the lip usually 3-lobed with 3 parallel fleshy keels, the apical lobe often bifurcate, the “bird-wing” type pollinia, at least the inner pair, and the SUBGROUP Turialvae which has a racemose and few-flowered inflorescence on an elongate peduncle, usually producing new racemes over the years, and thus pluri-racemose and filiform petals. The species is recognized by the few-flowered inflorescence, the large, green colored flowers with sepals .136" [34 mm] long, the lustrous yellow lip and the apex of the column with a reddish ring below the apex, the disc immaculate white, and the apical margin of the lip laciniate. It is very similar to Epidendrum xanthoianthinum Hágsater, but that species has somewhat smaller flowers with sepals 1.08" [27 mm] long, green with the lip yellow and a large reddish blotch on the disc of the lip, the apical margin of the lip slightly erose. Epidendrum pseudepidendrum Rchb.f., native to Costa Rica and Panamá, has dark green sepals and petals and the entire lip orange, with the margin short laciniate." Hagsater etal 2013
