fruit (5 lines in diameter). The broad usually very dense panicles are 

 an inch or two long. 



LupiNCs (Platycarpos) Orcuttii. Diffusely much branched 

 from the base, low (2 to 4 inches high), pubescent throughout with 

 short stiffish spreading hairs : leaflets 5, oblong-spatulate, 3 to 6 lines 

 long, shorter than the petioles : racemes numerous, sessile in the axils, 

 1 or 2 inches long, the scattered purple or reddish flowers 3 lines 

 long: pod oblong, 4 lines long, 2-3-seeded : seeds a line in diameter. 

 — Collected at Japa, in Lower California, near the boundary, by C. R. 

 Orcutt, July, 1884. Allied to L. pusillus. 



HosACKiA (Syrmatium) NANA. A dwarf prostrate very leafy and 

 slender cespitose perennial, canescent throughout with short white 

 spreading or subappressed hairs : leaflets 5 to 7, approximate, oblong- 

 obovate, folded, a line long or less upon a slender petiole 1 or 2 lines 

 long : peduncles shorter than the petioles, bearing 1 or 2 small flowers 

 subtended by a small bract : calyx a line long, the teeth about half the 

 length of the campanulate tube ; corolla white or purplish, 2 or 3 lines 

 hmg ; ovary 1-ovuled. — On the mesa of Toyalani, near Zuiii, New 

 Mexico; collected by Dr. W. Matthews, U. S. A., in 1883. 



Dalea Orcuttii. Perennial, with numerous short slender herba- 

 ceous subprocurabent or ascending stems (3 or 4 inches long) from a 

 woody branching rootstock, appressed silky-puberulent : leaves 4 to 6 

 lines long, the folded oblong-obovate leaflets (4 to 6 pairs) 1 or 2 lines 

 long, glabrous above : peduncles about equalling the leaves ; spikes 

 short (.V inch long), somewhat crowded, the flowers reflexed or spread- 

 ing : calyx short-villous, turbinate, the lanceolate acuminate teeth 

 equalling or exceeding the tube ; the purple OT-bicular banner and the 

 win^s scarcely exserted, the broad twice-longer keel purple on the 

 inner margin. — At To[)0 and in the Canon Cantillas, Lower Califor- 

 nia ; collected by C. R. Orcutt, in October, 1882, and July, 1884. It 

 was suspected that this might be the D. canescens of Bentham, collected 

 at Magflalena Bay, but a comparison made by Prof. Oliver at Kew 

 shows that, though allied to that species, it is not identical with it, the 

 pul)escence in D. canescens being of short somewhat sparse spreading 

 hairs, and the calyx very small (1 line long). 



Dalea (Xylodalea) megacarpa. Shrubby, densely white-to- 

 mentose throughout and conspicuously glandular-punctate : leaflets 5 

 or 6 pairs, suborbicular. retuse, L^ to 3 lines long : spikes rather dense, 

 becoming 4 to 7 inches long; bracts narrowly linear, equalling the 

 calyx: calyx turbinate-campanulate, with oblong obtuse teeth, shorter 

 than the tube ; petals yellow, becoming purplish brown, free and dis-
