10. L. littoralis Dougl. Chinook Liquorice. Steins slender, decumbent or 

 ascending, 1 to 3 feet long ; root yellow, somewhat fleshy ; stems hirsute with ascend- 

 ing hairs, the hairs sometimes dense and rather shaggy, especially below ; leaflets 

 appressed-hirsute, sometimes subglabrous above; leaflets 5 to 7, oblanceolate or 

 cuneate-oblong, acute, I/2 to 1 inch long, at least half as long as the petioles, strigose 

 on both sides and often somewhat silky; petioles mostly short, Y2 to IV2 inches 

 long; racemes (2 or) 3 to 8 inches long, the whorls discrete or sometimes the flowers 

 more or less scattered ; flowers S^/^ to 7 lines long ; calyx-lips of nearly equal length, 

 lower entire, upper slightly cleft; petals blue or lilac, the banner shorter than the 

 wings; keel ciliate; pods hirsute, % to 1% inches long; seeds elliptic, brown, with 

 black spots. 



Sea-beaches or dunes or bluffs along the coast line : Mendocino Co. to Humboldt 

 Co. North to British Columbia. May-July. 



Locs. — Fort Bragg, J. T. Howell 4256; Elk Eiver (mouth), Humboldt Co., Tracy 3745; 

 Humboldt Bay, Tracy 3556 ; Bucksport, Tracy 4785. A common plant on the Washington and 

 Oregon coasts, becoming less common as it extends southward. In Mendocino Co. it meets L. 

 variicolor Steud., by which it is replaced southward and to which it is closely related.

L. ABRAMSii C. P. Sm. Bull. Torr. Club 51:308 (1924), type loc. Los Pesares, Santa Lucia 

 Mts., Monterey Co., Abrams 7360. Banner pubescent dorsally (ex char.) ; said to belong to 

 the L. littoralis group. 



11. L. tidestromii Greene. Clover Lupine. Stems slender, decumbent, sev- 

 eral from the branched root-crown, 4 to 12 inches long; herbage silvery-silky, espe- 

 cially the leaves; leaflets 3 to 5, oblanceolate, acute, 5 to 11 lines long; petioles 5 to 

 9 lines long; racemes loose, 1 to 3 inches long, the whorls 1 to 4 (or 5) ; flowers 5 to 

 6 lines long; pedicels 1 to 2 lines long; petals blue; white or yellow center of banner 

 turning violet; keel ciliate; pods 10 to 12 lines long, 5 to 8-seeded. 



Sand dunes near the coast: Pt. Pinos, Monterey Co.; Pt. Reyes, Marin Co. 

 May-June. 



Tax. note. — Lupinus tidestromii is related to L. littoralis. The pubescence of pedicels and 

 calyces is more spreading in the former. The calyx-tube of L. tidestromii is almost Ys longer 

 and broader than in L. littoralis and the upper portion of it more scarious or gibbous, while in 

 L. littoralis it is not scarious or gibbous or only slightly so. The upper calyx-teeth in L. variicolor 

 are broadly triangular with a wide v-shaped notch, whereas in L. littoralis the teeth are oblong- 

 lanceolate with narrow sinus.

12. L. variicolor Steud. Particolor Lupine. Stems slender, decumbent or 

 prostrate, several from a woody base, forming a low plant commonly i/^ to l^/^ feet 

 high; herbage scantily or somewhat densely hairy-pubescent or villous; leaflets 

 6 to 9, oblanceolate, acute, I/2 to 1 inch long; petioles slender, % to 1% inches long; 

 racemes % to 2I/2 inches long, the distinct whorls 1 to 4; flowers 5 to 7 lines long; 

 pedicels 2 to 3 lines long; petals blue, purple, pink, white or yellow, the banner
