56 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 



i-3-veined. 



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

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

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



* Schoenolirion 



GG. 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 Lilium). 

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



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



II. 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) 

 JJ. 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. LILIUM (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- 



ticidal; 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. cernuum 

 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
