Leaves rising from the crown of the root, ovate-lanceolate, 
plicate, undulate,all the stronger ribs channelled above, pro- 
minent behind, tapering to a petiole, which isagain dilated 
at the base. Scapes several, erect, cylindrical, undivided. 
Bracteas alternate; acuminate, green; towards the bottom 
of the scape sheathing, higher up half-stem clasping, 
spreading, and half the length. of the germen. Spike ye 
right, crowded. Flowers each springing from the axil of a 
bractea, and snow-white, spreading nearly at right angles to 
the scape. Perianth three, outer segments lanceolate, each 
tipped with a green mucro ; two inner obovate-spathulate, 
with a white mucro. Lip longer than the corolla, 4-cleft, 
warted under the pollen mass, warts pointed, yellow, seg- 
ments spreading, the two lowest the longest, blunt, and 
diverging. Spur half as long as the germen, straight, 
cylindrical. Germen two inches long, very slightly fur- 
rowed, once twisted, so as to bring the spur below; in the 
bud it is above and crescent shaped. Pollen masses dry, 
in each cavity of the anther four spathulated lobes, two 
being longer than the others. The whole flower, but 
especially the germen and spur, are very slightly pubescent. 
The germen and every part of the flower is snow-white, 
except the tips of the outer segments of the perianth, which 
are bright green, the warts on the lip, which are yellow, 
and the pomt of insertion of the pollen masses, which is
