PEA FAMILY 277 



association of characters in specimens as frequently differing as agreeing with the descriptions. 

 The var. arizonicus C. P. Sm. has smaller flowers but is apparently not otherwise differentiated 

 (Needles, Jones). The var. pondii C. P. Sm. is described as having leaflets truncate, rounded or 

 emarginate at apex and as having compact racemes, but authentically named specimens may 

 have lax instead of compact racemes (Tia Juana, L. Cal., Orcutt), or have flowers within the size 

 limits of var. arizonicus (Coyote Caiion, Colorado Desert, Hall 2821). When too near the species, 

 var. pondii becomes var. inopinatus C. P. Sm. with leaflets of var. pondii and flowers either the 

 size of those of the species or of var. arizonicus. The differences in the shape of the banner of 

 var. pondii and var. inopinatus as indicated by the figures (Bull. Torr. Club 47:500-501) do not 

 hold constant, authentically named specimens showing that either form may have the banner 

 distinctly clawed or distinctly not clawed. It is well stated by C. P. Smith (I.e. 47:492) that 

 none of the varieties can be segregated upon the basis of pubescence, each showing the whole 

 range of variations from densely villous to glabrate. We find, too, geographic segregation un- 

 satisfactory. The two following varieties are less indistinct. 



Var. barbatulus Thornber. Stems stout, hollow, more erect ; leaflets broadly oblanceolate, 

 10 to 20 lines long, 3 to 6 lines wide; racemes usually 6 to 12 inches long; bracts sometimes 

 equaling the calyx. — Needles, Parish 9617; Cottonwood Spr., Cottonwood Mts., Jepson 12,553; 

 Whitewater, Jepson 11,638; San Felipe Narrows, e. San Diego Co., Jepson 8793, 12,527. 



Var. brevior Jepson var. n. Diffuse, 3 to 9 inches high ; leaflets truncatish or obtuse ; 

 racemes nearly sessile, not exceeding the foliage, Y2 to 2 inches long; flowers 3 to 4 lines long. — 

 (Eamosi diffusi, unc. 3-9 alti; foliola subtruncata vel obtusa; racemi subsessiles, unc. %-2 

 longi, folia non superantes.) — Desert sands, in washes, western Colorado Desert: Myers Creek 

 bridge, foot of Mountain Sprs. grade, Jepson 11,771 (type) ; Sentenac Valley (e. of San Felipe 

 Valley), Jepson 8782; Wagon Wash near Sentenac Canon, Jepson 12,506. The racemes and 

 flowers are both shorter than in the species.

42. L. citrinus Kell. Gold Lupine. Plants diffusely branched from the base, 

 4 to 7 inches high; herbage white-villous; leaves a little crowded, the leaflets rather 

 densely pubescent; leaflets 6 to 8, oblanceolate, obtuse, 5 to 12 lines long, shorter 

 than tiie petioles; racemes 1 to 2 inches long, only slightly exceeding the foliage, 

 the flowers not in whorls; flowers 4 to 41/0 lines long, soon deflexing; upper and 

 lower calyx-lips about equal, the upper deeply cleft, the lower minutely 2 or 3- 

 toothed; corolla bright orange; keel glabrous above, ciliate below near claw; pods 

 51/2 lines long, 11/2 to 2 lines wide, glabrate, 2 to 4-seeded, pendulous on strongly 

 reflexed pedicels; seeds quadratish, grayish, mottled with black.

43. L. stiversii Kell. Rose-and-Yellow Lupine. (Fig. 189.) Stem diffusely 

 branched (as if sympodially) from or near the base, 7 to 13 inches high; herbage 

 finely and rather sparingly pubescent; leaflets 5 to 7, broadly cuneate-obovate, ob- 

 tuse or acutish, mucronate, 1/2 to 11/2 inches long, shorter than the petioles; racemes
