Common NameSonnenmark's Cyrtochilum [Jan Sonnemark Swedish Orchid Enthusiast current]
Flower Size 1" [2.5 cm]
Found in Azuay Ecuador in high altitude grassy, shrubby plains at elevations around 2400 to 3600 meters as a medium sized, cold growing terrestrial with caespitose, ovoid pseudobulbs enveloped basally by 5 to 6, distichous, foliaceous sheaths and carrying 1 to 2, apical, erect, conduplicate, linear-elliptic to obovate, acute to obtuse, sometimes apiculate, subpetiolalte base leaves that blooms in the summer fall and winter on an axillary, arising form the uppermost sheaths, erecet to slightly arching, to 32" [80 cm] long, almost straight panicle,branches widely spaced, 2" [5 cm] long, each 5 flowered, racemose above, many flowered inflorescence with adpressed scale like floral bracts and carrying campanulate to stellate flowers.
"Cyrtochilum soennemarkii is distinguished by the tall and erect loosely flowered inflorescences, carrying dull brownish to clear yellow flowers commonly with a purplish column and a bright yellow to orange, basally gibbous, carnose and somewhat tuberous callus. Cyrtochilum soennemarkii differs from the similar but previously misapplied Cyrtochilum viminale (Rchb.f.) Dalström by the gibbous and convex lip with a carnose and bright yellow to orange callus, versus a basally straight, slightly elongated, smooth, dorsally furrowed and bifurcated callus of the same ivory white color as the lip lamina for C. viminale. Cyrtochilum soennemarki is distinguished from all other yellow-flowered and superficially similar species by the gibbous lip with a carnose and slightly tuberous callus." Dalstrom 2015
