Native country not clearly known. 
Bulb oblong, half an inch thick, with loose white membranous 
outer coats and numerous bulblets and thick white fleshy root- 
lets. Leaves all radical, contemporaneous with the flowers, linear, 
nine or ten inches long, three to three and a half lines broad, 
flaccid in texture, a rather pale green, quite naked, with a distinct 
keel and a very faint glaucous bloom on the under side. Scape 
erect, terete, pale green, slender, equalling the leaves. Spathe 
quite membranous, white with a faint tinge of green or violet, 
twelve to fifteen lines deep, two-cleft about half-way down, the 
divisions lanceolate. Peduncle slightly drooping, about three 
inches long from the base of the spathe. Flowers always solitary, 
the tube infundibuliform, half to five-eighths of an inch deep, 
with the purplish green keels of the segments continuous to its 
base. Segments nearly equal, spreading horizontally when the 
flower is fully expanded, oblong, rounded at the apex with a 
slight often quite cuspidate point, three-quarters of an inch deep, 
five lines broad, pure white with a distinct keel of purplish green 
on the outside. Stamens in two sets of three each, the anthers of 
the longest just attaining the throat of the flower, the top of 
those of the shorter set just reaching the base of the others. Ovary 
obovate-oblong, rather shorter than the erect style, which equals 
the shorter stamens ; the papillose stagma densely trisulcate. 
Comes very near 7’. uniflora, Lindley, good figures of which 
will be found in Bot. Mag. 3327, and Bot. Reg. 1921, and with 
the same alliaceous scent, but a more showy plant, with broader, 
paler and more flaccid leaves, a longer peduncle, considerably 
larger and less deeply-colour flowers, with the segments not nar- 
rowly oblong-lanceolate, narrowed from just above half-way up to
