Inflorescence: nodding , many flowered raceme , proceeding from the base of tiie 

 pseudobulb. Sepals narrowly lanceolate and acuminate, of a greenish purple colour. 

 which varies in intensity in different specimens ; the uppermost is pressed close to 

 ihe petals, ihe two side ones are turned back till thcy touch each other. Petals are 

 thin, pale pink, stained with dull purple, rather broader than the upper sepal , with 

 which they are parallel, so as to form a kind of arch over the column , but nol 

 louching it; somctimes however they separate and fall backwards towards the lateral 

 sepals or simply spread away from the column; such was the case in the original 

 of the drawing so that it has at one lime parts of the aboblished genus Myanthus 

 and at another a disposition peculiar to itself. Lip of a new form lo this gonus. Lan- 

 ceolate oulline hollowed at its base into a deep pouch; edges and point curved inwards 

 along the margin , towards the base il is bordered by a flne fringe of slender hairs. 

 From ihe front edge of the pouch to nearly the aprx is carried a fleshy plate, planled 

 perpendiculary upon tlie lip and from 4—5 lines deep, which, next the pouch, dividcs 

 inlo 2 lobes, but otherwise is periectly entire except on the upper edge, which ia 

 some varieties is unequally toothed. Colour in the flgured pale greenish pink, spotled 

 with dull but deep purple , in a plant of Horticultural Society Garden ivory white 

 eventually changing to cream colour. Column is spotted in ihe variety, wiih a 

 spotted lip, nearly plain in that with ,the white lip. Found but by Karwinski and 

 Hartweg near Oaxaca.
