Common Name or Meaning Dubbeldam's Masdevallia [Dutch Co-collector of the type current]
Flower Size .8 x 3.2" [2 x 8 cm ]
Found in Zamora-Chinchipe province of Ecuador without locational data as a mini-miniature sized, presumably at least cool growing caespitose epiphyte with slender, erect blackish ramicauls enveloped by 2 to 3 tubular sheaths and carrying a single, erect, coriaceous, dark green, elliptical, obtuse to subacute, cuneate below into the blackish petiolate base leaf that blooms in the fall on an erect, slender peduncle 2.2" [5.5 cm] long, with a bract near the base from low on the ramicaul, single flowered inflorescence with as long as the pedicel and carrying flowers with light yellow green dotted with red within sepals, yellow-white with purple dots petals and a white, marked with purple lip.
"The species is very similar to Masdevallia dalesandoi differing most in the labellum. Although probably of little consequence, the leaves of M dubbeldamii are broad and Obtuse while those of M dalesandroi are narrow and acute. The sepals and petals are similar in size, shape and color, but the lip of M dubbeldamii is rhombic while M dalesandroi is elliptical. In addition, the margins of the lip of M dubbeldamii are minutely crisped and undulate and markedly constricted below the apex to create a terminal lobule." Luer 2009
