 pink or red. Stamens borne on base of perianth -segments. 

 Fruit a loculicidal capsule. Seeds black, wrinkled. 



Leaves 2-4. 



Ovary not long-crested. 



Leaves nearly as long as peduncle... 1. A. acuminntum 

 Leaves at least a third longer than pe- 

 duncle 2. A. Diehlii 



Ovary conspicuously 6-crested 3. A. bisceptruin 



Leaf 1; ovary very long-crested 4. A. nevadense 



1. A. acumlnatum Hook. Mostly from solitary coated bulbs 

 (not rhizome-producing), the outer coats of which are coarsely 

 and distinctly quadrately to hexagonally reticulated. Involucre 

 of 2 papery bracts. Leaves narrowly linear. Flowers light 

 pink to dark rose-purple. Perianth-segments with acuminate,

 dry soil in open fields. May-June. 



2. A. Diehlii Jones. (A. tribracteatum Diehlii Jones.) From 

 solitary, mostly red-coated, nearly spherical bulbs (not

 rocks on mountain-sides. May. 



3. A. bisceptmm Wats. From solitary light-coated and 

 faintly-reticulated bulbs. Scapes often in pairs. Perianth - 

 segments acuminate, not serrulate, slightly longer than the 

 stamens; the alternate stamens with a dilated base. In the 

 mountains. 



4. A. nevadense Wats. From brown-coated, ovate bulbs, 

 without rhizomes, but producing whitish bulblets; outer bulb- 

 coats with irregular reticulations. Leaf round, channeled on

 usually 2; ovate, acute, reddish-green. Sepals lanceolate, 

 spreading. Petals white or pinkish. May. 



8. ZYGADENUS. Star Lily. 



Stem simple, scape-like. Leaves folded lengthwise; from
