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

Flower Size 3/4" [2 cm]

Found in Ecuador at altitudes of 1200 to 2500 meters as a miniature sized, caespitose, warm 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 has a congested, many flowered, 12"+ [30 cm+], triangular inflorescence with imbricating floral bracts and successively opening, single flowers that are held well above the leaves occuring in the summer.

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
