Roots long, branched, fibrous from the base of the slender bulbs, and 

 with short creeping underground stems, bearing small bulbs at the 

 extremity, (the infant plant of another year). The whole plant smooth, 

 except a slight roughness in the lower part of the stein. Leaves nearly 

 round, linear, of a deep shining green, keeled at the back with a 

 slender rib on each side, the radical ones mostly two, longer than the 

 stem, flaccid, those of the stem short, rigid, erect, three or four in num- 

 ber, the upper ones almost like bractea, flattened at the base, and 

 somewhat sheathing the stem. Stem erect, from four to six inches 

 high, round, slender, scarcely striated, bearing at its extremity a 

 solitary flower, white, the outer side marked with branched reddish 

 purple veins, sometimes green, which Mr. W. Wilson observes changes 

 to a purple after impregnation takes place, the perianth of six lanceo- 

 late erect or somewhat spreading pieces, each having a little above its 

 base a rather large yellow gland. Stamens on slender filaments, 

 simple, slender, about half as long as the perianth. Anthers roundish, 

 yellow, of two cells, bursting laterally. Style short, stout, erect. 

 Stigma obtuse, of three angles. Capsule roundish oblong, mem- 

 branous, of three cells. Seeds few, angular, wrinkled, brown.
