78 LILIACEAE. 



age with the characteristic odor and taste of onions. 

 Flowers in a terminal simple umbel, subtended by 2 or 3 

 membranous, separate or united bracts. Pedicels slen- 

 der, not jointed. Perianth persistent, its segments dis- 

 tinct or united at the base. Stamens inserted on the 

 bases of the perianth segments; filaments filiform or 

 dilated, sometimes toothed. Style filiform, jointed. 

 Capsule obovate-globose, obtusely 3-lobed, often crested, 

 loculicidally dehiscent. Seeds obovoid, wrinkled, black. 



1. A. haematochiton Wats. Scape slender, 1-3 dm. high, some- 

 what compressed and 2-edged; tunicated bulb oblong, crowning a 

 horizontal rhizome, its coats deep reddish-purple, shining; leaves 

 several, linear, flat and rather thick, 2-4 mm. broad, about equaling 

 the scape; bracts 2, short connate; umbel erect or somewhat nodding, 

 deep purple or rose-color; segments ovate-lanceolate, acute, 6-8 

 mm. long; stamens and style very slender, scarcely equaling the 

 segments; ovary truncate with very short rounded crests; capsule 

 obcordate, 4 mm. long. 



On dry rocky hillsides. Santa Monica Mountains and Verdugo 

 Hills. April-May. 



2. A. serratum Wats. Scape terete, slender, about 1 dm. high; 

 bulb nearly globose, without rhizome, its coats with a distinct close 

 horizontally serrate denticulation; leaves 2 or more, somewhat 

 shorter than the scapes; bracts narrowly acuminate; perianth seg- 

 ments broadly ovate-lanceolate, 8-12 mm. long, acute or somewhat 

 acuminate, nearly straight and rather rigid, the inner shorter and 

 sometimes serrulate; filaments all with a narrowly deltoid base; 

 crests very narrow central.

4. MUILLA Wats. 



Scape from a fibrous corm and bearing an umbel sub- 

 tended by several small scarious bracts. Leaves mostly 

 few, very narrow, nearly terete. Pedicels not jointed. 

 Perianth subrotate, persistent, of 6 nearly equal slightly 

 united oblong-lanceolate segments, greenish or yellowish 

 white with a dark 2-nerved midrib. Stamens inserted 

 near the base; filaments filiform, slightly thickened 

 toward the base or petaloid; anthers versatile. Ovules 

 8-10 in each cell; style clavate, persistent and at length 

 splitting. Capsule globose, scarcely lobed, loculicidal. 

 Seeds compressed and angled. 



1. M. serotina Greene. Scapes 3-5 dm. high, glabrous; leaves 

 3-4 dm. long, subterete, the upper surfaces nearly plane, the lower 

 convex and sharply 7-striate, the striae retrorsely scabrous; umbel 

 40-70-flowered; pedicels nearly 10 cm. long; perianth rotate about
