5. L. rivularis, Dougl. Stout, erect, 2 to 6 feet high, nearly glabrous, the 

 short and silky pubescence closely appressed, or very rarely spreading on the calyx 

 and pedicels : stipules subulate or setaceous ; leaflets 7 to 10, about equalling the 

 petioles, to 5 inches long, oblanceolate, acute or the -lower ones obtuse: raceme 

 long-peduncled, often 1 to 2 feet long; bracts setaceous, exceeding the calyx: flowers 

 scattered or subverticillate, purple or sometimes white : bractlets caducous ; upper

Var. latifolius, Watson. Leaflets 5 to 7, spatulate or oblanceolate, obtuse and 

 inucronulate or the upper acute : the pubescence upon the calyx more frequently 

 spreading. Proc. Am. Acad. viii. 525. L. latifolius, Agardh, Syn. 18; Lindl. 

 Bot. Reg. t. 1891. 



From the Columbia River to Southern California, common ; the typical form frequent in the 

 Sierra Nevada ; the variety more common nearer the sea. 



6. L. Burkei, Watson. Resembling L. rivularis, but distinguished by broader 

 stipules, and the lower leaves long-petioled : raceme usually short and dense, the 

 pedicels mostly only 1 or 2 lines long ; bracts villous and often persistent : the 

 pubescence of the calyx somewhat villous and more or less spreading : pod 8-seeded. 

 Proc. Am. Acad. viii. 525. L. polyphyllus, Watson, Bot. King Exp. 55. 



On the east side of the Sierra Nevada from Northern Nevada to Montana, and probably to be 

 found in Northeastern California. 



7. L. littoralis, Dougl. Stems slender, decumbent or ascending, 1 or 2 feet 

 long, often not succulent, leafy : pubescence silky, rather thin, short and appressed, 

 or villous and spreading especially about the axils : leaflets 5 to 8, oblanceolate or 

 cuneate-oblong, acute, a half to an inch long, at least half as long as the petioles : 

 racemes short ; bracts setaceous, exceeding the calyx : flowers blue or violet, with some 

 yellow, verticillate or scattered, on rather short pedicels : calyx large, with small 

 bractlets: keel ciliate: ovules and seeds 10 to 12. Lindl. Bot. Reg. t. 1198; 

 Hook. Bot. Mag. t. 2952 ; Watson, 1. c. 526. L. versicolor, Lindl. Bot. Reg. 

 t. 1979. L. Nutkatensis, var. fruticosus, Bot. Mag. t. 2136. 



Near the coast, from Vancouver Island to San Francisco. The taper root is said to be known 

 in Washington Territory as " Chinook Liquorice." 



++ ++ ++ Leafy and branching ; the petioles not longer than the leaflets : flowers sub- 

 verticillate, yellow in L. Sabinii : bracts deciduous, shorter than the calyx : ovules 

 6 or 7, rarely 8, only 5 in L. Sitgreavii : mostly erect or ascending, 1 or 2 feet high. 



8. L. Sabinii, Dougl. Stout, erect : pubescence short, appressed, silky : stipules 

 long, setaceous; leaflets 8 to 11, oblanceolate, acuminate, 2 or 3 inches long, silky 

 on both sides : raceme 6 to 10 inches long, rather dense and long-peduncled ; bracts 

 exceeding the calyx, linear-setaceous : flowers bright yellow : upper calyx-lip short, 

 nearly entire, the lower narrow : standard emarginate, naked ; keel ciliate : pod un- 

 known. Hook. Fl. i. 166 ; Lindl. Bot. Reg. t. 1435 ; Watson, 1. c. 527. 



This has been collected only by Douglas and Nevius, in the Blue Mountains of Oregon, but may 

 occur in Northern California ; distinguished by its long racemes of yellow flowers. 



9. L. albicaulis, Dougl. Pubescence short and appressed, or more or less vil- 

 lous and spreading, often scanty : leaflets 5 to 9, oblanceolate, 1 to 3 inches long, 

 acute, pubescent on both sides or glabrous above : raceme mostly short-peduncled ; 

 bracts subulate : calyx long, with nearly equal lips, the upper narrowed and shortly 

 toothed : petals blue, verging to white ; the standard naked, acute, with the margins
