21. CALOCHORTUS, Pursh. 



Perianth deciduous, of 6 distinct more or less concave segments, the 3 outer 

 (sepals) lanceolate, greenish and more or less sepaloid, the inner (petals) mostly 

 broadly cuneate-obovate, usually with a conspicuous glandular pit near the base, and 

 very variously colored. Stamens 6, on the base of the segments, included ; anthers 

 linear to oblong, basifixed, dehiscent laterally. Ovary sessile, triquetrous and 3-

 long, inembranaceous, 3-angled or 3-winged, mostly septicidally dehiscent. Seeds 

 numerous, in 2 rows in each cell, somewhat flattened, with a thin membranous white 

 or brownish often loose testa. Stems usually flexuous and branching, from mem- 

 branous- or rarely fibrous- coated corms ; leaves few, linear-lanceolate, radical and 

 cauline, the latter alternate and clasping, all with many nerves and transverse vein- 

 lets ; flowers few, showy, terminal on the branches or umbellately fascicled. Baker,

A genus confined to Western America, ranging from British Columbia to Mexico and from 

 the Pacific to the Rocky Mountains. The half-dozen Mexican species are somewhat peculiar and 

 form a distinct section. The whole genus is unique, in some of its characters allied to the Tulip 

 of the Old World, in others to the Melanthaceous group of genera. The colors of the flowers are 

 in some of the species very variable.
