unchanging yellow ; the keel somewhat produced or narrowed at the incurved 

 apex, acutish. Oregon and Washington Territory. 



8. H. Heermanni, Durand & Hilgard, in Pacif. R. R. Surv. 5, part 3, p. 6, 

 t. 4. Villous-puhescent, diffusely mueh branched (from a " suft'rnticose" 

 base ?) very leafy. Leaflets obovate, roundish, or oval-oblong, 25 lines 

 long. Umbels 4 9-flowered and with a nnifoliolate bract ; the peduncle 

 often equalling the leaf. Teeth of the loosely villous calyx considerably 

 shorter than the campanulate tube. Flowers 2 lines long, yellow turning 

 purplish ; the keel with a broad and very obtuse summit. Southern part of 

 California. Tejon Pass, Dr. Heermann. Near Los Angelos, Mr. Wallace. A 

 very branchy and Moribund species, the pubescence in kind nearly that of 

 H. tomentosa, but far finer and less copious. 



Var. ? orbicularis. II. orbicularis, Torr, ined. Villous-downy : the leaf- 

 lets almost orbicular, 1 to 2 lines long ; and the umbel only 3 5-flowered. 

 Sand hills near San Francisco, California, Rev. A. Fitch. Flowers small in 

 proportion, scarcely larger than in the next, and perhaps a form of that 

 species, 



9. H. micrantha, Nutt., 1. c, under Drepanolobus. Diffusely procumbent 

 from an apparently annual root, mimutely villous-pubescent, at length 

 glabrate, slender. Leaflets mostly 5 or 6, obovate-oblong, 1^ to nearly 3 

 lines long. Umbels 3 5-flowered and without a bract, short- peduncled. Teeth 

 of the pubescent calyx not half the length of the tube. Flowers only a line 

 and a half long ; the short incurved apex of the keel obtusish. California. 

 Here described, not from the original of Nuttall, from near Monterey, but from . 

 a specimen in Mr. Durand's herbarium, named by Nuttall, from "Catalina," 

 probably therefore collected by Dr. Gambell. The root seems to be annual. 



10. H. prostratA, Nutt., 1. c, under Drepanolobus. H. dccumbens, var. 

 glabriuscula, Hook, and Am. Bot. Beech, p. 137 ? ex. char. Glabrate, the 

 nascent parts minutely silky-puberulent, diffusely procumbent ; the branches 

 Blender. Leaflets 5 or 7, oblong-obovate, obtuse, about 3 lines long. Um- 

 bels lax, 5 10-flowered and with a nnifoliolate bract, on slender peduncles 

 exceeding the leaves. Teeth of the campanulate calyx very short. Flowers 

 3 lines long, yellow tinged with red. Said by Nuttall to be " suffruticose," 

 but the specimen before me does not indicate it. Coast of the southern part 

 of California, Nuttall. 



2. EUHOSACKIA, Benth. Legume linear, straight or nearly so, not ros- 

 trately attenuate. Keel of the corolla not falcately attenuate upwards, most- 

 ly very obtuse. 



* Subpahiatifolice. Petiole short or nearly wanting, bearing 3 6 crowded- 

 pinnate or quasi-palmate leaflets. Stipules reduced to blackish glands. 

 Peduncles 1 2-(rarely 34-) flowered : bract nnifoliolate, rarely 3-foliolate. 

 Flowers yellow, turning purple. Vexillum tapering to the base, but hardly 

 unguiculate, not distant from the other petals ; keel very much shorter 

 than the wings, straightish, narrowish ; claws not exserted out of the calyx. 

 Stems branching, from a perennial root, rigid. 



f Peduncles elongated, all exceeding the leaves. 



11. H. rigida, Benth. PI. Hartw. p. 305. Silky or cinereous-pubes- 

 cent, a span to a foot high. Leaflets 3 5, crowded on a very short petiole, 

 cuneate oblong or obovate. Teeth of the calyx shorter than the tube. Mon- 

 terey, California, Coulter. I have seen no Californian specimen of this. 

 But I now refer to it some plants which I formerly took for varieties of the 

 next species, especially Dr. Bigelow's from Williams' River, a tributary of 

 the Colorado on the eastern or New Mexican side, (in Bot. Whipple's Exped.
