* * Stipules gland-like, dark-colored : leaflets 3 <o 9 ; rhachis mostly elongated : pe- 

 duncles I - several-flowered, bracteate at the summit or sometimes naked : claws of 

 the petals not exserted from the calyx. 



+- Perennials : floweis rathei- large : umbels 3 - 8-floivei-ed, 



8. H. grandiflora, Uuiitli. Mostly tall uml atout, 1 to f) fuel liigh, iiioro ur 

 less apprcbsed bilky-pubusccnt : Icailuts 5 to 7, on an elongateil rhachis, oliovate to 

 oblanceolate, 6 to I) hnes long, acutish : peduncles elongated : umbel 3 - S-liowered, 

 usually subteutltid by a single leaflet : flowers nearly sessile, 6 to 1 1 lines long, 

 yellowish or greenish white, often tinged with purple : calyx half as long, tlie subu- 

 late teeth nearly equalling the tube : pod slender, elongated, glabrous. — Trans. 

 Linn. Soc. xvii. 3GG. //. ochroleuca, Nutt. iu Torr. & Gray, Fl. i, 323. 



From Mendocino Co. und the luoulh of the Yuba to Suuta Barbara; Gimdahipe Island, I'ldnwr. 



9. H. rigida, Bcuth. A span to a foot high or more, more or less appressed 

 silky-pubescent ; leaflets 3 to 5 on a very short petiole, or palmately crowded and 

 sessile, obovate to oblanceolate, acutish, 3 to 8 lines long : peduncles usually ex- 

 ceeding the leaves, 1 - 5-flowered, with a sessile 1 - 3-foliolate bract or naked :

Arizona, Sononi, and laslward, and probably to be found within the aoutheastcrn limits of tlio 

 State; Tantillas MIh., below San Diogu, I'almcr. Coulter's original simciniens were refened to 

 Monterey, doubtless through mistake. 11. puhenUa, Henth., with linear or oblanceolate leaflets 

 upon a more developed rhachis, and //. IFHghtii, Gray, with flowers on shorter peduncles or 

 sessile, are apparently but forms of H. rigida, and may likewise occur in California. 



Dr. Palmer collected at the 13ig Cafion of the Tantillas Mts. a very sindlar plant, but with the 

 pod broader and (piite glabrous. The same was found by Newberry at Sitgreaves Pass in Arizona, 

 and perhaps also by IMgelow on Bill Williams Ilivcr. It may bo distinct. 



-t- -k- Annuals: rhachis of the leaf somewhat dilated: flowers smaller. 



-n- Peduncles mostly 2 - 5-flowered : standard remote from the vnngs. 



10. H. maritima, Nutt. A span high, mimitely strigose-puberulent or nearly 

 glabrous : leaflets mostly 5, succulent, obovate to oblanceolate, 4 to 6 lines long : 

 peduncles about equalling the leaves : umbel usually subtended by a 1 - 3-foliolate 

 bract : flowers yellow, 4 lines long : calyx-teeth linear-sul)ulate, about equalling the 

 tube : pod an inch long, narrow, 10- 12-seeded. — Torr. & Gray, Fl. i. 32G. 



Near the sea, from Santa Barbara to Los Angeles. 



++ ++ Peduncles \-2-floivered, about equalling the leaves : petals all approximate. 



11. H. Strigosa, Nutt. Strigosely pubescent, small, diffusely spreading, pros- 

 trate or ascending: leaflets 5 to 9, obovate or usually linear-oblong, 1 to 5 lines long: 

 bract 1 - 5-foli(^late or wanting : flowers liglit yellow, 3 to 5 lines long or less : keel 

 very obtuse, shorter than the wings ; standard attenuate into the claw : calyx-teeth 

 subulate, shorter than tlie tube : pod narrow, an inch long, 10- 12-seeded. — Torr. 

 & Gray, Fl. 326. //. microphylla, nudiflora & rubella, Nutt. 1. c. 



Frequent through the lower i»art of the State, from Monterey and Calaveras Co. to the Colo- 

 rado River. Very variable. 



12. H. parviflora, nentli. Glabrous or nearly so : stems very slender, uscentl- 

 ing, a span high or less : leaflets 3 to 5, obovate and very small to narrowly oblong 

 and 6 to 8 lines in length : bract 1- 3-foliolate : flowers very small (about two lines 

 long), yellow : keel with a sharp incurved apex, nearly equalling the wings ; blade 

 of the standard cordate : pod 6 to 12 lines long, 5 - 7-seeded, compressed and often 

 contracted between the seeds. — Bot. Keg. xv, under t. 1257. Lotus micranthiis, 

 Benth. in Trans. Linn. Soc. xvii. 367. 



From Monterey and Sacramento northward to the British boundary. Very variable.
