486 BOTANY. 



3. A. CBKNUUM, Eoth. Leaves lineai, keeled ; scape angled, rather stout;, 1-2° higB ; spathe-seg- 

 ments usually small ; umbel loose, nodding ; stamens and style exserted.— W. New York to N. Carolina 

 and west to Wisconsin, the Saskatchewan and Washington Territory ; Wyoming to New Mexico, (848 

 Fendler, 1913, 1914 Wright ;) Eaton Mts., (Abert;) Roubideau's Pass, (Gunnison ;) Colorado, (350 Parry, 

 540 Hall & Harbour ;) Bridger's Pass, (H. Engelraann ;) Ft. Colville and Puget Sound, (Lyall, WHkes.) 



(6.) Capsule not crested. 



4. A. VALIDUM, S. Watson. Scape stout, 1-2^° high, angled ; leaves broad-linear, 3-7" wide, elon- 

 gated ; spathe-segments broad and connate ; umbel capitate, many-flowered, erect or rarely subnodding ; 

 sepals white or pinkish, long-acuminate, 4" long, equaling the stamens, shorter than the style.— In the 

 California Sierras and Nevada. See page 350. 



5. A. BREVISTYLUM, S. Watson. Scape slender, l-li° high ; leaves long-linear, 1-3" wide ; spathe 

 l-valved, obliquely connate-oampanulate ; umbel erect, few-flowered, with short pedicels ; sepals bright 

 pink, long-acuminate, 4" long ; stamens half as long, exceeding the style. See page 350. 



* * Perennial, with a series of separated corm-like bulbs, rooting from the stem above ; outer coats 

 chartaceous, minutely oontorted-reticulate ; spathe large, 2-valved ; capsule not crested. 



6. A. UNlFOLiUM, Kellogg. Proo. Calif. Acad. 2. 112, fig. 35. Scape stout, 1^-2° high, terete; leaves 

 several, long-linear, 2-4" wide, flat ; umbel erect, usually many-flowered, spreading ; pedicels I-I4' 

 long; sepals pink, 5-6" long, broad, acute, exceeding the stamens and style. — California; Tamul Pass, 

 (Bigelow ;) near San Francisco, (Kellogg ;) Ukiah, (Bolander.) A. falcifolium, Var. /3., of Whipple's 

 Eeport. The specific name is a misnomer. The remarkable character of the bulbs and rootstock would 

 suggest a distinct genus, but there is nothing in flower or fruit to separate it from' Allium, and the 

 taste is decidedly alliaceous. Plate XXXVI. Fig. 9. Bulbs, rootstock and base of stems ; natural size.

* * * Bulbs without evident perennial rootstocks ; leaves sheathing, (solitary in A. Nevadense;) 

 spathes 2- (rarely 3-) valved, (in A. Saniornii, 4-valved.) 



(ffl.) Capsule crested. 



7. A. STBLLATUM, Fras. Coatings membranous, not at all fibrous ; scape slender, 1-1^° high, angled ; 

 leaves very narrowly linear, elongated ; umbel 10-25-flowered, rather loose ; pedicels 4-6" long ; stamens 

 equaling the pinkish ovate-oblong acute (3" long) sepals ; style exserted ; crest large.— On the Saskat- 

 chewan. Specimens from Hooker in Herb. Gray. 



8. A. EETICULATUM, Fras. Coats densely fibrous ; scape 6-15' high, subterete ; leaves very narrowly 

 linear, elongated ; umbel many-flowered, spreading ; stamens and style shorter than the usually acute 

 (3-4" long) sepals ; crest mostly short. — From the Saskatchewan to the Columbia and south to New 

 Mexico. Very variable. 



Var. a. Low, 6-8' high; sepals 3" long, white or slightly pinkish, acuminate.— Saskatchewan, 

 (Douglas, Bourgeau;) Upper Missouri, (Sucldey ;) Spokan River, (Wilkes;) Columbia River, (Wyeth;) 

 Colorado, (545 Hall & Harbour, 552 Vasey ;) Indian Territory, (328 Palmer.) A. angulosum, Nutt. 



Var. /3. Taller, (10-15',) slender ; bulb less densely fibrous ; sepals white or pink, 3-4" long, acumi- 

 nate and strongly cariuate, sometimes but'little exceeding the stamens.— Colorado to the Columbia ; has 

 been confounded with A. stellatum. Upper Missouri, (Nicolet ;) Colorado, (546 Hall & Harbour ;) Idaho, 

 (Spalding;) Washington Territory, (Lyall, Wilkes, 226 Geyer.) A form near this, but with umbels 

 mostly bulbiferous and coats densely fi-brpus, was collected in the Wahsatch and on Bear River, Utah. 

 See page 350. 



Var. y. Like the last, but the pedicels rather more slender, the sepals usually more recurved, and 

 the whole lower stem, with the bulb, thickly fibrous-coated.— New Mexico, (1915 Wright ; ) and Cambridge, 

 from seed. 



Var. d. Low ; capsule long-crested ; sepals pinkish, 3-4" long, short and narrow, or very broad and 

 longer.— New Mexico, (1916 Wright, Bigelow, Newberry, Palmer, Dr. Seguin.) 



9. A. Sanbornii, Wood. Proo. Acad. Phil, 1868, p. 171. "Bulb ovate, white;" scape tall, slender; 

 spathe 4-valved ; flowers very numerous, ou very slender (6-8" long) spreading pedicels ; sepals light 

 pink, 3" long, erect, shorter than the stamens and style.— N. California, (Shelton, Pratteu, Wallace.)

 339. A. ocddentaU, Gray, Proc. Arm: Acad. 7. 390. A. acuminatum, Var. /3. gracUe, Wood, I. 0.) Bulb 

 small, reddish, the coats minutely wavy-reticulated ; scape slender, 10-15' high ; leaves very narrowly 

 Imear; flowers white, numerous, crowded on slender (3-6" long) pedicels; sepals 3" Ion a-, usually in-
