Camassia esculenta Lindl. — Fine specimens from Marin Co. (Dr. Stillman) 

 to Portland (Mr. Walker, Mrs. Sliepley). Bulb white, furnishing to the Indi- 

 ans a rich diet. Leaves broadly linear, nearly the length of the scape (12 — 

 18'') ; raceme 6 — 10-flowered. Flowers 1'' long, blue, alternate. Sepals lance- 

 oblong, 5 — 7-veined. Cells of the capsule about 12-seeded. 



ALLIUM, Linn. 

 ^ Bracts of the spathe 2, rarely 1 or 3. 



* Sepals acuminate, longer than the stamens. 



A. FALCiFOLiUM Hook. Bulb globular, white ; leaves 2 or 3, linear, recurved, 

 shorter than the scape ; spathe colored, of 1 or 2 bracts, shorter than the pedi- 

 cels ; flowers 10 — 30, rose-purple, two or three times shorter than their stalks ; 

 sepals lance-ovate, carinate-acuminate, more or less glandular-serrulate, 

 recurved, more than twice longer than the unequal stamens. — San Diego to 

 Salem (Oregon). 10 — 20^. Pedicels 1^ — 18^^. March — May. Hooker's plant 

 had "lanceolate" leaves. None wider than lance-linear appear among my 

 specimens. 



A. DouGLASSii Hook. Bulb ovoid, white ; leaves linear, erect, mostly two, 

 shorter than the scape ; spathe 2 bracted, about as long as the pedicels ; 

 flowers about 20, rose-{)urple, two or three times shorter than their stalks ; 

 sepals ovate, gibbous at base, rather acuminate, straight, a third longer than 

 the subequal stamens. — Throughout Oregon, California and Nevada. 10 — 

 20''. Pedicels 1''. San Diego specimens have sepals broadly ovate, merely 

 acute. Nearly allied to A.falcifoliimi, but readily distinguished by the sepals 

 (sepals and petals). 



A. ACUMINATUM Hook. ? Bulb ovoid, often purplish ; leaves 2 — 3, narrowly 

 linear, shorter than scape ; umbel densely oo -flowered, globular, 1^ or more in 

 diameter; spathe 2 — 3-bracted; pedicels not longer than the purple flowers 

 (3 — 5'''') ; sepals ovate or oval, acuminate, gibbous at base, near twice longer 

 than the stamens ; capsule ripening 1 — 3 black seeds. — Hills, Santa Clara Co. 

 to the Wahlamette. Scape 1 f. or more. Umbel small and compact, 20 — 40- 

 flowered, very pretty. April, May. 



/?. gracile. Scapo gracillimo ; umbella 20-flora, f pol. diam. ; segmentis 

 (siccis, post anthesin) inflectis, albis ; semine unico. — On Feather Rivor, 

 Oroville. 



** Sepals acute, equalling the stamens. 



A. TRiBRACTEATUM Torr. Bulb ovate; scape low (3 — 4'') ; leaves 2, linear, 

 much longer than scape ; umbel 15 — 20-flowered ; spathe of 3 ovate bracts; 

 sepals lanceolate, acute ; about equalling the stamens ; capsule broadly 

 obovate, 3-lobed, cells 2-seeded. — Hill sides, Duffield's, Sierra Nevada (P. R. 

 R. Rep. iv, 92). V. s. in herb. Torr. 



A. AMPLECTENS Torr. Bulb large ; scape low, flexuous ; leaves 2, longer than 

 scape, filiform ; umbel 3 — 6-flowered ; spathe of two round concave bracts 

 embracing the flowers ; sepals oblong, obtuse ; capsule 3-lobed, depressed, 6- 

 seeded. — Hill sides, Sonoma, Cal. (Torrey, 1. c, V. s. in herb. Torr. 



*** Sepals acute, stamens exserted. 



A. CERNUUM Roth.? Bulb ovoid-oblong, tapering upwards; leaves 5 — 8, 

 narrow-linear, erect, shorter than the scape; umbel fastigiate, nodding, finally 

 erect, with a short 2-leaved spathe, and about 20 small roseate flowers ; sepals 

 oblong-ovate, acute, shorter than the stamens and slender style; ovary 

 3-lobed, crowned with a 6-lobed crest! — Dalles of the Columbia and east, l^
