breadth : inflorescences short, 3-4-flowered, soon recurving : ' flowers and fruit much as in 

 the last but beak of keel more slender. — Britton in Wheelock, 1. c. 143. P. Arizonce, var. 

 tenuifolia, Chodat, 1. c. 109.— W. Texas, Tom Greene Co., Tireedi/, and what appears to be

++++++ Glabrous or nearly so : low shrubs of the Pacific Slope. 



P. cornuta, Kellogg. Branching shrub, 2 to 6 feet high : leaves elliptic-oblong to oval, 

 obtuse, often thickish, 6 to 15 lines long, rather abruptly narrowed at the base to distinct 

 but very short petioles : outer sepals tomentulose over the whole outer surface, rarely almost 

 glabrous : flowers 4 lines in length, yellowish or greenish M-hite, borne in short mostly ter- 

 minal racemes : wings oblong : petals scarcely equalling the keel ; this tipped with a slender 

 straightish beak : capsule orbicular, retuse, 4 lines in diameter ; seeds very hairy with deeply 

 lobed caruncle half their length. — Proc. Calif. Acad. Sci. i. 62 ; Wheelock, 1. c. 147. P. Cali-

 to the next species. P. cucull.ata, Newberry, Pacif. R. Rep. iv. 76, not Beuth. P. Califor-

P. Californica, Nutt. Similar in foliage but mostly of lower stature ; stems shorter, more 

 slender and numerous : flowers of two kinds ; the larger sliowy, half inch in length, roseate, 

 borne in short terminal racemes, mostly sterile : outer sepals ciliolate, otherwise glabrous : 

 wings spatulate : petals mostly exceeding the keel ; this bearing a short thickish mostly 

 recurved beak : inconspicuous fertile flowers upon basal shoots : capsule ovate to suborbicu- 

 lar, 3 to 4 lines in diameter ; soft puberulent seeds capped by a less deeply lobed caruncle. —

 identical with the very different and probably Mexican P. Nutkana) ; Greene, Fl. Francis.

•i— -)— Branches mostly indurating with age and spinescent-tipped. 



P. subspinosa, Watson. Puberulent or rarely pubescent to almost glabrous, 2 to 6 inches 

 or more in height, from a long stout ligneous root and considerably branched stock : leaves 

 lance-oblong to elliptic, spatulate or almost linear, of firm texture, acute to very obtuse, 5 to 

 10 lines long, narrowed to a sessile base : flowers 4 to 5 lines long : elliptic-oblong mostly acute 

 or acutish wings and tips of tlie lateral petals rose-purple ; keel yellow, with a distinct but 

 blunt beak : obovate retuse glabrous or glabrate capsule veiny. — Am. Nat. vii. 299 ; Ben-

P. acanthoclada, Gray. Stems more ligneous, 2 or 3 feet high, becoming an inch in 

 thickness (ace. to Jones), at first cinereous-tomentulose, copiously branched ; branches end- 

 ing in divaricately spreading spines : leaves much as in the last, but in the type smaller, 3 to 

 5 lines in length, 1-nerved : flowers white or with petals purplish-tinged at the tips: wings 

 obovate, rounded at the apex : keel with a short blunt or in some cases almost obsolete beak 

 or mere ridge; fruit (ace. to Jones) oblong-ovate, 2| lines long, deeply notched. — Proc.

Var. intricata, A. Eastwood. Leaves about twice as large (8 or 10 lines long), gla- 

 brate or nearly so : wings "tipped with rose-color": fruit oval, deeply emarginate, about 2 

 lines in length, "red on the margin." — Proc. Calif. Acad. Sci. ser. 2, vi. 283. — Near tlie
