262 FLORA. 



Pedicels filiform. Perianth with a very narrow tube and a salverform limb, 

 persistent, the 6 linear-oblong lobes spreading, nerved, shorter than the tube. 

 Stamens borne near the top of the perianth -tube, shorter than the lobes; filaments 

 filiform; anthers linear, their sacs introrsely dehiscent. Ovary ovoid, 3-celled; 

 style filiform; stigma small. Capsule oval or obovoid, 3-angled, sessile, obtuse, 

 loculicidal. Seeds several in each cavity, angled. [Greek, meaning white lily.] 

 A monotypic genus of northwestern N. Am.

 leaves 5-25 cm. long, 2-6 mm. wide; flowers 3-8; perianth -limb about 1.2 cm. 

 broad, the lobes acute; perianth-tube 2-5 cm. long, less than 2 mm. in diameter; 

 anthers coiled, at least when dry; capsule 6-8 mm. long, erect, leathery. In 

 sandy soil, S. Dak. and western Neb. to CuL April -June. 



3. ALLIUM L 



Bulbous herbs, characteristically odorous (alliaceous), the bulbs solitary, or 

 clustered on short rootstocks. Leaves narrowly linear, or rarely lanceolate or 

 oblong, sheathing, basal, or sometimes also on the stem. Stem (usually a scape) 

 simple, erect. Flowers white, purple, pink or green, in a terminal simple umbel, 

 subtended by 2 or 3 membranous separate or united bracts. Pedicels slender, not 

 jointed. Perianth persistent, the 6 segments separate, or united by their very 

 bases. Stamens inserted on the bases of the perianth-segments; filiments filiform 

 or dilated, sometimes toothed; anther-sacs introrsely dehiscent. Ovary sessile or 

 nearly so, completely or incompletely 3-celled; style filiform, jointed, usually 

 deciduous; stigmas small; ovules 1-6 in each cavity. Capsule loculicidal. [Latin 

 for garlic.] About 275 species of wide distribution. Besides the following, some 

 40 others occur in the western U. S.
