Root perennial, tuberous, spreading considerably and
branching. Leaves generally 5 on the leaf-shoots in the flowering
season, all more or less falcate, some of them very
much so, the longest 10 inches and a half in length, though
they do not appear to be much above half that length, being
so very falcate : the broadest about an inch in breadth,
gradually becoming smaller downwards, glaucous and very
strongly striated. Scape 2-or-3-flovvered, clothed with short
spathaceous leaves, which scarcely reach from one joint to the
next, terminal flowers sometimes 2 from the same scape, but
more generally one, also 1 from the bottom, and 1 from the
side. Spathe 2-glumed, clasping each other, and the peduncle,
ovarium, and a good part of the tube, inflated about the
middle, acute, the inner one longest, green, more or less
marked with violet, particularly near the point. Flower of
a purple violet. Feduncle longer than the ovarium, nearly
but not quite cylindrical. Ovarium very short, about half
the length of the tube, 6-lined, at first cylindrical, but soon
becoming 3-sided. Tube of the perianthium green tinged
with blue upwards, obtusely angular : 3 outer segments
ovately obovate, rounded at the points, undulate, tapering to
the base, but not so much so as the inner ones, from the
base to the bend, and a little above, striped with white :
from the base to the middle, clothed with a close line of white
hairs, tipped with violet, and towards the end nearly' altogether
violet : 3 inner segments erect or bent a little inwards at
