North West Coast, Menzies ! Douglas ! Unalaschka, Rudolph ! Pallas ! 

 {Pursh .') p. Rocky Mountains in lat. 55°, Drummond, ex Hook. — Flowers 

 very large, in a loose raceme. Corolla blue, variegated with red and yellow 

 veins. 



22. L. affinis (Agardh) : stem herbaceous, clothed with scattered spread- 

 ing hairs ; leaflets 7, obovate, attenuate at the base, pubescent on both sides, 

 shorter than the petiole ; stipules setaceous, about half as long as the leaflets ; 

 bracts equalling the unexpanded verticillate flowers ; calyx bracteolate, the 

 upper Up deeply 2-cleft ; keel ciUate. Agardh ! I. c. p. 20. (excl. syn. ?) 



California, Douglas ! (v. sp. in herb. Lindl.) — Differs from L. Nootka- 

 tensis, according to Agardh, in the much shorter and more sparse pubescence, 

 the leaflets pul^escent on both surfaces, the shorter and more obtuse bracts, 

 smaller (blue) and more regularly whorled flowers, more evidently bracteo- 

 late calyx, with the upper lip almost 2-parted, &c. 



23. L. versicolor (Lindl.) : stem ligneous at the base, decumbent, silky ; 

 leaflets 9, obovate-linear, silky, the margins canescent, shorter than the pe- 

 tiole ; stipules setaceous, hairy ; flowers verticillate ; calyx somewhat brac- 

 teolate, the upper lip emarginate ; keel ciliate ; legumes villous. Lindl. ! 

 bot. reg. t. 1979. 



California, Douglas, (v. sp. cult.) — Stem about 2 fe^et laigh, much 

 branched. Flowers variable in color, laetween rose-color, violet, pale blue, 

 greenish white, and pink on the same raceme. Liridl. — Allied to L. 

 rivularis. 



t t t Stems procumbent, persistent : calyx ebracteolate, veiy deeply bilabiate : 

 keel ciliate. Agardh. 



24. L. rivularis (Lindl.) : stems a little shrubby, decumbent, sericeous ; 

 leaflets 7-9, narrowly obovate and elongated, slightly emarginate, as long as 

 the petiole ; stipules somewhat falcate ; raceme elongated, loosely flowered ; 

 the flowers mostly verticillate, bluish lilac-color ; calyx very deeply bilabi- 

 ate, ebracteolate, the lips almost entire. Agardh. — Lindl..' bot. reg. t.

California, Douglas ! Nuttcdl .'—Stems leafy, 2-4 feet in length, when 

 young (as also the leaves and calyx) minutely silky and shining. Leaflets 

 narrowly obovate-spatulate, obtuse, mucronulate. Bracts very caducous. 

 Pedicels rather shorter than the calyx. Flowers very large. Legume 

 many-seeded. — Except in the color of the flowers, this species is scarcely to 

 be distinguished from L. arboreus, which Mr. Nuttall suspects may have 

 had a Californian origin. This is perhaps the L. arboreus p. odoratissimus 

 of Fischer & Meyer (irid. sem. St. Petersb. 1835). which they state to be the 

 L. sericeus of Eschscholtz (in mem., acad. St. Petersb. 10. p. 589) ; while 

 the L. sericeus. Hook. S^- Am., bot. Bcechey, is, as they conceive, L. Cha- 

 missonis, Esch. 



* * Legumes i-^-seeded : seeds roundish, the kilum somewhat oblique : steins 

 mostly persistent and silky.
