high from a stout rhizome; leaves ample, 2-8 lines broad, often nearly as 
long as the scape: umbel often slightly nodding, with-2-4 bracts, densely 
many-flowered; pedicels rather stout, 4-8 lines long: flowers rose-color to 
nearly white; segments 3-4 lines long, narrowly acuminate: stamens and 
style usually exserted: capsule subglobose, not crested. In wet places in 
the mountains, Oregon to California and Nevada. 
§ 2 Bulbs globose to ovoid, mostly solitary, not rhizomatous ; 
coats fibrous or membranaceous. Leaves narrowly linear, flat or 
channeled. Scapes terete or nearly so. Umbels erect. 
* Bulb-coats more or less fibrous: leaves several.

6-10 inches long: umbel densely many-flowered: pedicels slender, 6-12 
lines long, spreading or reflexed: segments of the perianth pale rose-color 
to white, about 4 lines leng, Janceolate, acute or acuminate, strongly nerved, 
rigid in fruit, sometimes but little exceeding the stamens: capsule crested. 
In low meadows, Oregon and Washington to Idaho.

4-5 lines long: umbel usually many-flowered: pedicels 4-12 lines long, 
segments of the perianth pink to white, 4 lines long, ovate-oblong. acute, a 
little exceeding the stamens: cells of the ovary with two fleshy ridges at 
the summit. In wet places, eastern Oregon and Washington. 
A. collinum Dougl. in Herb. I have no specimens of this, it is poorly 
described as follows. ‘‘ Perianth-segments ovate-lanceolate, acute, 4 lines 
long, twice longer than the slender stamens and style: capsule very ob- 
scurely ridged toward the summit ’’. Blue Mountains, Oregon. 
A. scilloides Donugl. in Herb. This is equally obscure with the last. 
‘* Perianth-segments oblong-lanceolate obtuse, 3 lines long, a half longer 
than the stamens: ovary not atall crested. Priest’s Rapids, Columbia river. 
A. acuminatum Hook. FI. ii, 184, t. 196. Scape 3-10 inches high:

late with acuminate recurved tips, dark rose-color to nearly white, rigid in 
fruit, a third longer than the stamens, the inner ones undulate-serrulate :

A. Bolanderi Watson |. c. 229. Scape very slender, 3-10 inches high: 
bulbs oblong, propagating by filiform runners; the one producing the 
scape remaining firm until the following season but not flowering again, 
but producing a new bulb that flowers the following season: leaves terete,
