Common Name Carruther's Masdevallia [English Botanist early 1900's]

Flower Size .8" [2 cm]

Found in Morona-Santiago and Zamora-Chinchipe provinces of Ecuador at altitudes of 1200 to 2500 meters as a miniature sized, caespitose, cool to cold growing epiphytic herb with slender, erect ramicauls enveloped by 2 to 3 tubular sheaths carrying a single, apical, erect, coriaceous, narrowly elliptical, subacute to obtuse leaf that is narrowly cuneate below into the subpetiolate base that blooms in the summer on a congested, 12"+ [30 cm+], triquetrous, successively single, many flowered inflorescence with imbricating, as long as to shorter than the pedicel floral bracts and flowers that are held well above the leaves.

"Characterized bythe long, triquetrous peduncle, a congested raceme of successive flower with a shallow cup and a broad, verrucose to spiculate synsepal that is longitudinally sulcate along the veins and with the margins of the sides recurved. The lip is distinguished by prominent, wing-like marginal folds and the epichile is convex, markedly verrucose and apiculate." Luer 2000

Masdevallia torulosa is often cited as a synonym of this species but its lip has two basal ear-like lobes that are not present in M carruthersiana so I have left them separate pending more research
