callosities, narrowly constricted and somewhat jointed in the 
middle, the upper portion petaloid. Column short, erect. An-

above, 3-8 inches long, acute or acuminate, somewhat scabrous on the 
veins beneath: racemes pubescent: bracts large and foliaceous, lanceolate 
or linear-lanceolate, as long or longer than the flowers: pedicels slender,

united and galeate. Lip free, concave, contracted and some- 
what jointed in the middle. Column slender, elongated, Anther 
shortly stipitate, so as to be nearly or quite above the level of the
