Perianth deep rose-color, mixed with green ; leaflets ovate-lanceolate. Stamens exserted : 

 filaments flattened ; the 3 interior ones deeply 3-cleft ; the two lateral segments naked at the 

 summit. Capsule obtusely triangular.

Bulb about an inch long. Leaves 4-8 inches long and 1-3 inches wide, acute. Scape 

 naked, 9-12 inches high, nearly terete, or sometimes slightly ancipital. Spathe of 2 mem- 

 branaceous acuminate leaves, deciduous. Umbel globose, about an inch and a half in diameter. 

 Perianth white ; the leaflets somewhat spreading. Filaments ovate lanceolate : anthers 

 oblong. Ovary 3-lobed : style about the length of the stamens. Capsule obtusely triangular 

 and somewhat 3-lobed, green. Seeds obovoid, black and shining.

 Europe.
