Roots: rather long, simple, brown (even in the youngest of them), thick, 
fleshy fibres, proceed from the lower part of the stem. Stem forming an 
oblongo-ovate bulb, sheathed in a distichous manner with the broad bases 
of the leaves, which are of a pale green colour, and submembranaceous ; 
this bulb tapers at the base into a slender cylindrical stem, covered with 
sheathing scales. Leaves 6 to 8 inches long, lanceolate, rather obtuse, 
waved, subcoriaceous, glabrous, distichous. Scapes one or two in num- 
ber, a foot and a half high, arising from a scaly sheath at the base of the
