Common Name Gentry's Sigmatostalix [American Orchidist in Ecuador 1900's]

Flower Size .4" [1 cm]

Found in northwestern Ecuador at elevations around 700 to 850 meters as a miniature sized, warm growing epiphyte with ovate, flattened, ancipitous pseudobulbs enveloped basally by several, conduplicate sheaths with the uppermost being leaf bearing and carrying narrowly elliptic-oblong, acute, narrowing below into the conduplicate, petiolate base leaves that blooms in the winter through summer on a lateral, basal, through the uppermost leaf axils of the sheaths, erect, to 6" [15 cm] long, paniculate, shortly branched, each branch successively single flowered over a prolonged time inflorescence with several, remote, close tubular bracts.

Similar to S amazonica but differs in the shape of the callus with 3 fleshy ribs inside the cavity and an elongate, upturned, finger-like projection from the lower portion rather than a simple hollow cavity and a pair of erect, projecting lobes on the underside
