var. — flava. 



Flowers smaller than those of the typical Masdevallia rnaculala, with 

 shorter sepaline tails and of a uniform tawny yellow. 

 M. maculata flava, supra. 

 Discovered by Wagener, in the neighbourliood of Caracas, and sent 

 by him to the Botanic Garden at Berlin, where it flowered for the 

 first time in Europe in 1847. The variety appeared amongst an 

 importation of the species from Caracas by Messrs. Sander and Co., 

 in 1881. 



M. Melanopus. 



Leaves oblanceolate, 4 — 5 inches long, narrowed below into slender 

 petioles, bidentate at tip. Scapes numerous, longer than the leaves, 

 racemose, 5 — 7 floAvered. Flowers Avhite, sparingly speckled with purple ; 

 perianth tube shortly campanulate, three-angled, gibbous below ; free 

 portion of sepals sub-orbicular, concave within, keeled behind, and con- 

 tracted into rather short, slender, bright yellow tails ; petals linear-oblong, 

 minute ; lip tongue-shaped, dilated at the apex into a round yellow- 

 terminal lobe.

Id. III. (1875), p. 136. M. polysticta, Hook. f. in Bot. Mag. t. 6258, not Rchb. 



A small-flowered species, one of a batch of three or four discovered 

 by Roezl in the temperate regions of the Andes of northern Peru, 

 and sent by him to M. Ortgies, Inspector of the Botanic Garden at 

 Zurich. It is one of the most attractive of the racemose Masdevallias 

 (sub-section Amandce), reminding one of the charming little Odonto- 

 glossum blandum. The specific name, from /itfXoi' (melan), " black,^^ 

 and TTOVQ (pous), "a foot," probably refers to the blackish stain some- 

 times seen on the scape just below the ovary. 



M. militaris. 



"All' coccinete, tepalis inequalibus, binervis ; labello apice dilatato 

 integro. Folia oblonga, acuta, basin versus anguste cuneata. Pedunculus 

 validus folio suo vulgo dimidio longior violaceus. Perigonii tubulus 

 incurvus septemlinearis, mento omnino obtusato evanescente, dein 

 bilabiatus ; labium superius a basi angustissima triangula, linearisetaceum.
