Common Name Spruce's Masdevallia [English Orchid Collector 1800's]

Flower Size 2/5" [2 cm]

Found in Amazonas state of Venezuela, Peru and Amazonas state of Brazil in low, tropical and wet, montane forests at elevations of 100 to 900 meters as a mini-miniature sized, hot to warm growing epiphyte with erect, slender ramicauls enveloped by 2 to 3 tubular sheaths carrying a single, apical, erect, coriaceous, elliptical, obtuse leaf and flowers in the late fall through earlier summer on a slender, arising from low on the ramicaul with a bract near the base, 2.8" [7 cm] long, succesively [3 to 4], single flowered, triquetrous inflorescence with a thin, tubular, shorter than the pedicel floral bract holding the flowers just at leaf height.

" Distinguished by the successively few flowered raceme borne by a slender peduncle, considerably more slender than that of the similar M bicolor. The peduncle in the lower portion is triquetrous but towards the apex it becomes terete. Sometimes the peduncle is totally terete or totally triquetrous as seen in M infracta." Luer 2000
