of four to five or six moderately-sized flowers. Pedicels short, 
not longer than the small fleshy dracts. Sepals and petals all 
directed downwards, but curved forwards, narrow-lanceolate, 
nearly equal, pale sulphur-yellow. Zip superior; it may be de- 
scribed as ovate in general form, of a thick and fleshy texture, 
the ground-colour white, three-lobed; the lateral lobes small, 
ovate, obtuse, moderately spreading, the middle lobe large, sud- 
denly reflexed, acute, having a cavity (and externally a tubercle 
corresponding with it a little below the apex); the whole upper 
surface studded with soredia, or small rough prominences, ar- 
ranged in lines, and of a rose-colour; the base beneath is pro- 
longed into a large pouch or blunt spur, as long as the ovary ; 
this is white, tinged with purple. Column rather short, terete, 
and somewhat gibbous below, apterous above, flattened in front, 
and bearing the stigma. Anther-case terminal, subhemispherical, 
erect, two-celled. Pollen-masses two, tapering into slender stalks, 
which are attached to a white triangular gland. Ovary straight, 
not twisted, short, three-lobed, nearly turbinate, yellowish, 
streaked with pale red.
