5 6 LILIACEAE (LILY FAMILY) 



E. Inflorescence distinctly a raceme or panicle, with scarious bracts; pedicels 



jointed; anthers versatile. 



F. Stem simple; inflorescence a raceme; perianth segments 3-7-veined, 17-30 



mm. long. CAMASSIA (p. 61) 



FF. Stem branched; inflorescence a raceme or panicle; perianth segments 



1-3-veined. 



G. Stem-leaves few; perianth segments 5-10 mm. long, apparently i-vemed 



but closely 3-veined; style short. — Mountain plants, not common. (Gk. 



schoenos = a reed, lirion = a lily; apparently referring to the reed-like stems.) 



* Schoenolirion 

 p-G. Stem leaves rather numerous; perianth segments 16-20 mm. long, 

 plainly 3-veined; style long. U. C. — (Gk. chloros = green, gala = milk; 

 from the greenish white juice.) Chlorogalum pomeridianum (soap-root) 



EE. Inflorescence not distinctly racemose, with foliaceous bracts or none; pedi- 

 cels not jointed; anthers basifixed (except in LUium). 

 H. Perianth segments all alike; capsule loculiddal; style present. 

 I. Leaves only 2, basal, wide; capsule 3-angled. ERYTHRONIUM (p. 60) 

 n. Leaves more than 2, not all basal. 

 J. Perianth segments 0.8-1 cm. long, -white; stem 5-13 cm. high; leaves 

 grasslike, not in a whorl, basal ones exceeding the stem: capsule 3-angled. 

 W. C. E. — (Probably in honor of A. J. Lloyd, an English surveyor and natu- 

 ralist. Lloydia serotina (wHiTE-FLOWERING grass) 

 J J. Perianth segments 2.5-10 cm. long, mostly not white; stem mostly 

 higher; leaves mostly not grasslike, often in whorls, not exceeding the 

 stem; capsule 6-angled. 

 K. Perianth segments oblanceolate; nectary a linear groove; bulb scales 

 lanceolate. LILItTM (p. 58) 

 KK. Perianth segments lanceolate; nectary a shallow pit; bulb scales 

 wider than lanceolate, very thick. FRITILLARIA (p. 59) 

 HH. Outer perianth segments smaller then the inner, greenish; capsule sep- 

 tiddal; style none. CALOCHORTUS (p. 60) 



ALLIUM (Onion) 



Perennial, mostly with coated bulbs, with onion-like odor. Leaves 

 basal, linear or lanceolate. Pedicels not jointed. Perianth segments 

 nearly equal, lanceolate to linear, i-veined, more or less gibbous at base. 

 Stamens 6, on the base of the perianth ; anthers versatile. Ovary sessile, 

 subglobose ; style filiform. Capsule obtusely 3-lobed. Seed obovoid, 

 wrinkled. — Many flavor milk when eaten by cattle. The cultivated onion 

 is A . cepa. (A Latin name for Garlic.) 



A. Perianth segments acute or blunter. 

 B. Perianth shorter than the stamens; bulb coat not reticulate. W. C. A. cemuum 

 BB. Perianth longer than the stamens. 

 C. Perianth twice as long as the stamens. 

 D. Ovary plainly 6-crested at the summit; bulb coat not reticulate. W. E. 



A. crenulatum
