of the Sierra Nevadas; San Diego to Marin Co, 
The following are probably forms of the same: A. crispum 
Greene, Pitt. 1 166. Bracts 2, abruptly acute; pedicels 12-20, 
about 1’ long, stoutish; sepals 3-4” long, the outer oblong-ovate, 
entire, the inner lanceolate with undulate margins; stamens a 
little over half the sepals; ovary not crested; San Luis Obispo 
Co., Calif; April. A. dichlamydeum Greene, Pitt. 1 166; a 
smaller plant with sepals 5” long, the outer oblong, abruptly 
acute and spreading, the inner Janceolate-oblong, erect, all 
entire; ovary crested; common around San Francisco in May and 
June. A. Stenanthum Drew, appears to be identical with A. 
serratum; was gathered at Pilot Ridge, Calif., in July 
41. A. attenuifolium Kellogg, Proc. Cal. Acad. 2 110. 
ticulations composed of delicate lines, at least he ET, 
ones very sinuous, the horizontal lines generally somewhat wavy, 
the meshes being more horizontally sinuous than serrate, the 
meshes are quite variable in different plants, some of them being 
broadly oblong and a little bent with the vertical lines very sin- 
uous as figured by Watson. These markings toward the tip of 
the coat turn into rectangular, vertically oblong ones with- 
out sinuosity, they occur on the thin coats, but the thick 
coats generally have transversely linear meshes with the 
horizontal lines distinctly wavy; the bulb coats are of two kinds, 
the outer 1 or 2 coats being very thin and white, an inner one 
or more being quite rigid and deep red; bulbs propagate by 
division and are small and nearly round, the solid part large 
and seales few; Jeaves and bracts two or more, the latter very 
broad and short; pedicels very slender, weak and generally 
sinuous; flowers broadly campanulate, about 2-4’ long, very 
delicate and thin, rose-colored to white; sepals ovate to lanceolate 
and acute; stems nearly 1° high or more; crests conspicuous, 
composed of broad ridges running from the style to the corner 
where they are enlarged and, on the mature capsule, look like 
horns. Mariposa Co., Calif., to Ore. Quite variable.
