4 lines long, twice longer than the slender stamens and style : capsule 

 very obscurely ridged toward the summit. — " Abundant on the Blue 

 Mountains," Oregon. 



17. A. scilloides, Dougl. in herb. An equally obscure species. 

 Perianth-segments oblong-lanceolate, obtuse, 3 lines long, a half 

 longer than the stamens : ovary not at all crested. — " Priest's 

 Rapids, Columbia River." 



■*-•*- Ovary rather obscurely crested : scapes low (4 to 10 inches): perianth- 

 segments (at least the inner ones) serrulate. 



18. A. acuminatum, Hook. Outer bulb-coats with a distinct 

 coarse quadrate to hexagonal reticulation: pedicels (12 to 30) 6 to 12 

 lines long : flowers deep rose-color, 4 to 7 lines long ; segments lance- 

 olate, with acuminate recurved tips, rigid in fruit, a third longer than 

 the stamens, the inner ones undulate-serrulate : filaments slightly 

 dilated below. — Fl. Bor.-Am. 2. 184, t. 196; Watson, King's Rep. 

 5. 352, t. 37, f. 6. A. Murrayanum, Regel, Gartenfl. 23. 200, t. 770. 

 From Washington Territory to Northern California, Nevada and 

 Utah. A. Elwesii, Regel, PI. Nov. fasc. 5. 50, is probably a form 

 of this species with more obtuse perianth-segments. 



19. A. Bolandeki. Bulb or coated corm propagating by one or 

 two very short lateral offshoots, the coats with a delicate close undu- 

 late-serrate reticulation: pedicels 5 to 15: flowers rose-colored or 

 pinkish, 4 or 5 lines long, the segments very narrowly acuminate, 

 nearly straight, twice longer than the stamens and style, the inner 

 ones strongly serrulate : filaments narrowly filiform, adnate to the 

 middle. — Humboldt County, California (n. 6556, Bolander ; n. 1011, 

 Kellogg & Harford ; Rattan). 



■*—*—*- Ovary distinctly 6-crested (obscurely so in n. 27, 28) : perianth-seg- 

 ments not serrulate, mostly rose-colored. 

 ■*+ Scapes often rather tall. 



20. A. stellatum, Fraser. Outer bulb-coats reddish, with a very 

 close linear longitudinal reticulation: scape 6 to 18 inches high: 

 umbel few-many-flowered; pedicels 4 to 9 lines long: perianth-seg- 

 ments 2 or 3 lines long, broad, acute : stamens and style exserted : 

 capsule prominently crested. — Ker, Bot. Mag. t. 1576; Hook. Fl. 

 Bor.-Am. 2. 184, t. 194. From the Saskatchewan to Wyoming. 



21. A. Sanbornii, Wood. Outer bulb-scales white, some with a 

 very minute irregular reticulation : scape usually a foot or two high : 

 spathe 4-valved : umbel usually densely many-flowered, the pedicels 

 3 to 8 lines long : perianth-segments 24 or 3 lines long, ovate-lanceo-
