 duncles \ - severalfloivered, hracteate at the summit or sometimes naked : claws of 

 tlie p>etals not exserted from the calyx. 



-{- Perennials : flowers rather large : umhels 3 - ^-floivered. 



8. H. grandiflora, Benth. Mostly tall and stout, 1 to 5 feet high, more or 

 less api)ie«sed silky-pubescent : leaJSets 5 to 7, on an elongated rhachis, obovate to 

 oblanceolate, 6 to 1) lines long, acutish : peduncles elongated : umbel 3-8-flo\vered, 

 usually subtended by a single leaflet : flowers nearly sessile, 6 to 11 lines long, 

 yellowish or greenish white, often tinged with jiurple : calyx half as long, the subu- 

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

 Linn. Soc. xvii, 366. H. ochroleuca, Is^utt. in Torr. & Gray, Fl. i. 323. 



From Mendocino Co. and the mouth of the Yuba to Santa Barbara ; Guadalupe Island, Palmer. 



9. H. rigida, Benth. 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 : 

 flowers half an inch long, yellow turning to brown : calyx-teeth half as long as the 

 tube or nearly ecpialling it : pod an inch long, rather broad, pubescent : seeds sub- 

 globose. — PI. Hartw. 305. 



Arizona, Sonora, and eastward, and probably to be found within the southeastern limits of the 

 State ; Tantillas Mts., below San Diego, Palmer. Coulter's original specimens were referred to 

 Monterey, doubtless through mistake. H. jmberula, Benth., with linear or oblanceolate leaflets 

 upon a more developed rhachis, and If. Wriyhiii, Gray, with flowei-s on shorter peduncles or 

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



Dr. Palmer collected at the Big Canon of the Tantillas Mts. a very similar plant, but with the 

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

 and jierhaps also by Bigelow on Bill Williams River. It may be distinct. 



-t- -4- Annuals: rhachis of the leaf someivhat dilated : flowers smaller. 



-i-+ Peduncles mostly 2-5flou<er€d : standard remote from the unngs. 



10. H. maritima, Xutt. A span high, minutely strigose-puberulent or nearly 

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

 peduncles about e(iualling the leaves : itmbel usually sid^tended by a 1 - 3-foliolate 

 bract : flowers yellow, 4 lines long : calyx-teeth linear-subulate, about equalling the 

 tube : pod an inch long, narrow, 10- 12-seeded. — Torr. & Gray, Fl. i. 326. 



Near the sea, from Santa Barbara to Los Angeles. 



+-!- -i-i- Peduncles 1 - l-flowered, 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-foliolate or wanting : flowers light yellow, 3 to 5 lines long or less : keel 

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

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

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



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

 rado Paver. Very variable. 



1 2. H. parviflora, Benth. Glabrous or nearly so : stems very slender, ascend- 

 ing, a span liigh 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 e([ualling the wings ; blade 

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

 contracted between the seeds. — Bot. Beg. xv, under t. 1257. Lotus micranthus, 

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



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