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, membranaceous, 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, Hn ear-lanceolate, radical and 

 cauhne, 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 '^enus confined to Western America, ranging from British Columbia to Jlexico and froni 

 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 1 ulip 

 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.
