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 

 m any -flow e red ; 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. 



A. Geyeri Watson Proc. Am. Acad, xiv, 227. Scape slender, 10-25 

 inches high : bulb elongated : leaves 2-4, slender, 5-10 inches long, rather 

 rigidly erect : spathe 2-valved ; the bracts broadly lanceolate, acuminate, 

 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 long, lanceolate, acute or acuminate, strongly nerved, 

 rigid in fruit, sometimes but little exceeding the stamens : capsule crested. 

 In low meadows, Oregon and Washington to Idaho. 



* * Bulb- coats not fibious : leaves 2-4, shorter than or about equal- 

 ling the scape. 



A. Douglasii Hook. Fl. ii, 184. Scape stout, 7-15 inches high : bulb 

 ovate, about an inch long, the coats not reticulated: leaves 2, flat, 5-10 

 inches long, about 6 lines wide: flowers very numerous, in a dense globose 

 umbel dark red, 3-4 lines long: segments lanceolate acuminate, scarcely

A. madidum Watson 1. c. 228. Scapes rather stout, 4-8 inches high : 

 bulbs ovoid, 4-8 lines in diameter : leaves 2, thick and channeled, 3-6 inches 

 long, 1-3 lines broad: spathe 2-valved, the bracts ovate to lanceolate, acute, 

 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 Dougl. 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 at all crested. Priest's Rapids, Columbia river. 



A. acuminatum Hook. Fl. ii, 184, t. 196. Scape 3-iO inches high : 

 bulb globose, 3-5 lines in diameter : leaves 2, terete, shorter than the 

 scape: spathe 2-valved, the bracts lanceolate, narrowly acuminate : pedicels 

 5-40, erect or ascending: segments of the perianth 5-7 lines long, lanceo- 

 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:

 California. 



Var. cuspidatum Fernald. " Perianth -segments smaller, abruptly 

 cuspidate. Near Wawawai, Washington." 



A. Bolanderi Watson 1. 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,
