sessile, two to six inches long, finely roughened on the margins 

 and on the veins beneath, in the central portion of the stem usually 

 in whorls of four to twelve but invariably scattering and alternate 

 above and below. The flowers are nodding and solitary, or two 

 or more in a simple whorl, or in vigorous plants more numerous 

 in two or more somewhat regular whorls. The perianth is widely 

 expanded and somewhat recurving; the ground color varies from 

 yellow to bright red according to the variety, with purplish-brown 

 blotchings. The flower-bud is almost terete in cross-section and 

 decidedly constricted near the base. The capsule is about one and 

 one-half inches long and oblong in shape. The bulbs are subglo- 

 bose white or yellowish in color, composed of thick short scales, 

 and propagating by a stout rootstock.
