Glabrous and flaccid perennial. Bulb ovoideo-globose, solitary, without 

 rhizome, with fibrous roots at the base, largest one about 2 cm in di- 

 ameter ; tunic entire, white, smooth, nerves loose and sub-flexuous with loose 

 and transverse veins between them mostly forming square areolae, cells 

 usually sub-square in form under the microscope. Leaves appearing after 

 the anthesis and persistent through the winter and lastly withering in the 

 late summer, flaccid, slenderly linear, gradually narrowed upwards with an 

 obtuse tip, about 30 cm or more long, about 2 j mm broad, compressed- 

 subtriangular, flat in front side, angular on the back. Scape appearing in 

 early autumn immediately after the death of leaves, 1-3 in number, erect, 

 protected with the sheath of former leaves at the base, flaccid, slender, 

 angular with very acute angles, sub-fistulose, green, about 20-30 cm long ; 

 involucral-bract shorter than the pedicels, 1-valved, narrowly oblong, tapering 

 upwards, involving the base of pedicels with the basal portion, hyalino-mem- 

 branaceous, several-nerved, about lj cm long ; pedicels loosely fastigiate or 

 erect-patent, umbellate, 2-7 in number, unequal in length, straight, filiform, 

 angular, glabrous, green, with abruptly enlarged receptacle at the top, 2-3 cm 

 long. Flower small, about 1 cm in diameter. Perianth 6, equal, 5-6± mm 

 long, campanulato-patent, aelherent to the basal-tube of filaments at the 

 base, thin, white often tinged with rose-colour ; lobes more or less reflexed, 

 oblong-strap- shaped, obtuse, entire, 1-nerved, 1 j mm broad. Stamens 

 G, not exserted, about three-fifths of the perianth in length, opposite to the 

 perianth lobes : filaments connate into a broad tube in one-half below and 

 the tube adherent to the basal portion of the perianth lobes, upper free 

 portion subulate, tapering upwards, straight, white, much shorter than the 

 perianth lobes, 1-nerved ; anther ovate-elliptical, 1 mm long, dorsifixed, 

 yellow. Ovary sub-globose, about 1 \ mm in diameter, obtuse-truncate at 

 the top and concave at the centre of it, shallowly 3-furrowed, 3-locular 

 each with 2 minute ascending ovules ; style erect, straight, narrow, slightly 

 longer than the ovary, with 3 oblong obtuse recurved and divergent stigmas. 

 Capsule sessile, glabrous, smooth, shallowly 3-furrowed at the* top and with 

 a small hollow in the centre of it, rounded at the back of each locula- 

 ment, about 6* \ mm in diameter, deep green when young. Seed usually only
