short appressed hairs, 2-3-seede(l, 4 or 5 lines long. — On sterile hill- 

 sides in Eastern Oregon (IF. C. Cusick, July, 1886). Differing from 

 L. aridus chiefly in the shorter and softer jjubescence, and the shorter 

 liedicels and racemes. 



LupiNus (Platvcarpos) Shockleyi. Nearly acaulescent, silky- 

 pubescent throughout, the hairs somewhat spreading on the petioles 

 and pedicels: leaflets 9 to 12, broadly sjjatulate or oblanceolate, gla- 

 brous above, 4 to 8 lines long : racemes shortly pedunculate, but little 

 exceeding or shorter than the leaves ; flowers scattered : calyx narrow, 

 silky ; petals " blue " or " purple," little exceeding the sepals, 2 or 3 

 lines long: pods oblong-ovate, papillose, villous only on the margins, 

 nearly 6 lines long, 2- seeded. — In the Mohave Desert, San Bernar- 

 dino County, California {Pa7'ish Brothers, May, 1882) ; near Soda 

 Spring, Esmeralda County, Nevada {W. H. ShocMey, May, 1886). 

 Near L. hrevicaulis. 



HosACKiA NiVEA. Annual, silvery throughout with closely ap- 

 pressed silky pubescence, the spreading branching stems several from 

 the base, 6 inches long or more : leaflets 3 to 7 on a short dilated 

 rhachis, oblong-obovate, obtuse, 2 to 6 lines long : peduncles about 

 equalling the leaves, 2-flowered, naked or with one or two small leaf- 

 lets at the summit : calyx 3 lines long, the lanceolate-triangular teeth 

 mostly shorter than the tube ; corolla purple, twice longer ; pods 

 straight, silky-pubescent, many-seeded, 6 lines long. — At Socono, 

 in northern Lower California ( (?. R. Orcutt, May, 1886). Of the 

 H. rigida group, but an annual. 



Dalea glaberuima. Glabrous throughout : stems erect and 

 branching (2 feet high), woody at base from an elongated slender 

 perennial root : leaflets 4 to 8 pairs, cuneate-obovate to -oblong, 

 rounded or retuse above, 3 to 6 lines long : spikes jjedunculate, nar- 

 row, loosely flowered, and becoming 3 to 6 inches long ; bracts obovate, 

 abruptly acuminate, equalling the calyx, herbaceous and persistent: 

 calyx turbinate-campanulate, scarcely over a line long, somewhat sca- 

 rious with broad acute green lobes; petals deep purple, 2 lines long: 

 stamens long-exserted. — On sand-hills, 30 or 40 miles south of Paso 

 del Norte, Chihuahua (C. G. Pringle, September, 1886). A quite 

 peculiar species, somewhat resembling D. tubercidata. 



Dalea Seemanni. Near D. Greggii, shrubby, erect, diffusely 

 much branched, the glandular-dotted branchlets finely tomentose : 

 leaflets 2 to 4 pairs, canescent with a very short subsilky pubescence, 

 on a rhachis 1 to 6 lines long, cuneate-oblong, obtuse, distinctly glandu- 

 lar beneath, 1 to 2i lines long: racemes shortly pedunculate, dense,
