under Hosackia. Decumbent or ascending, leafy and branching, silvery- 

 silky throughout : leaflets 3 — 7, obovate and rounded, or oblong and 

 acute, 2 — 7 lines long : umbels dense and capitate, on short simple- 

 bracted peduncles : fl. 4 — 5 lines long ; calyx half as long, its teeth fili- 

 form, silky, nearly as long as the tube. — From Yosemite, Chesrmi tfc Brew, 

 and the foot-hills of the Merced, Asa Gray, southward. Very probably 

 more than one species is embraced by this name and description. " H. 

 argentea," Kellogg, seems distinct ; but we can not at present make out 

 characters sufficient for its restoration. 



26. L. leucopliyllus, Greene, 1. c. HosacMa sericea, Bcnth. Trans. Linn. 

 8oc. 1. 0. Slender, sparsely leafy, 1 — 2 ft. high, silvery-canescent with a 

 close but short silky pubescence : leaflets 8, cuneate-oblong to linear, 

 1;,' — 3^ inches long : umbels few-flowered, sessile or short-peduncled : fl. 3 

 lines long ; calyx half as long, with slender teeth. — Plant with the habit 

 of L. glaher, but silky-pubescent. Evidently rare, and confined to Monte- 

 rey Co. 



27. L. procuiiibens, Greene, 1. c. and Bull. Calif. Acad. i. 82 (1885) 

 under Hosackia. Pubescence as in the last, but much more leafy and 

 diffuse : leaflets cuneate-obovate to oblanceolate, acutish, ig — 1 in- long : 

 fl. sessile, 1 or 2 only in each axil : calyx-teeth subulate from a broad 

 base, erect : pod nearly 1 in. long, straight, with an eusiform beak, 2- 

 seeded. — From Tehachapi, Kern Co., Mrs. Curran, southward and east- 

 ward along the mountains west of the Mohave Desert. May, Ji;ne. 



28. L. »va(leiisis, Greene, Pittonia, ii. 149 (1890) ; Bull. Calif. Acad. 



ii. 148 (1886), under Si/nnalium. Hosackia decuiiibens, var. ( ?) Nevadensis, 

 Wats. Bot. Calif, i. 138(1876). Diffiise, the slender branches hard and 

 wiry, at base more or less woody : sparingly villous or somewhat tomen- 

 tose : leaflets 3—5, cuneate-obovate, acute, 3 5 lines long : umbel many- 

 flowered, short-peduncled, 1-foliolate-bracted : calyx a line long, the 

 slender teeth % line : pod strongly arcuate, the slender beak longer than 

 the body. -Dry pine woods of the Sierra Nevada, from Sierra Co., Lemmuii, 

 to San Diego Co. In my first description of the species I erred in attri- 

 buting to it an annual root. It is, usually at least, perennial. In habit 

 and geographical range it is most unlike the next ; but the technical 

 characters of the two species are feeble. 



29. L. Doiig'lasii, Greene, 1. c, Hosackia decnmbens, Benth. Bot. Reg. 

 under t. 1257 ( 1829). Larger and more leafy than the last, decumbent at 

 base, the erect branches not wiry : pubescence more scant : fl. 4-7 lines 

 long ; calyx l^^ lines ; the slender teeth as long as the tube : pod longer, 

 less arcviate. — From Humboldt Co., Cliesuul ct- Hreir, northward.
