Dendrobium Calceolaria, Carey's MSS. 
Parasitic. Roots consisting of numerous, simple, waved, and stout fleshy 
fibres. Stem simple, cylindrical, jointed, striated, bearing towards the 
extremity several distichous linear-lanceolate, shining, thickish leaves, 
sheathing at the base. From the lower part of the stem, as it would 
appear (the drawing exactly represents the specimen communicated), 
springs the raceme, of about five, large, very handsome, and showy 
flowers. 
Peduncle 6-8 inches long, jointed, with sheathing scales at the joints. Seg- 
ments of the perianth nearly equal, elliptical or ovate, spreading hori- 
zontally, somewhat waved, the two lowermost running down, along with 
the base of the column and of the lip, into a thickened spur at the base 
where it unites with the base of the lip. They are of a delicate rose- 
colour, beautifully veined in a reticulated manner ; the spur tawny. 
Lip erect, jointed upon the prolonged base of the column, and doubled 
upon it, large, remarkably ventricose, so as exactly to resemble the lip 
of a Cypripedium, pale rose-colour, downy, with two deep rich brown 
spots within ; the base fulvous, attenuated, and forming with that of 
the column into an obtuse, broad spur. Column very short, purple on 
the back, for the greater part of its length united with the perianth, 
much prolonged down the front of the germen. Anther deep purple, 
operculiform, attached by a filamentous process to the top of the co- 
lumn, 2-celled, each cell having a dissepiment, and containing two 
double pollen, in form oblong, masses approximating and forming two 
pairs. Germen very long, pedunculiform, scarcely perceptibly twisted, 
slightly thickened upwards. Stigma a viscid, concave disc just beneath 
the anther.
