136 LEG-TJHTNOS.E. Hosackia. 



* * Stipules gland-like, dark-colvred : leaflets 3 to 9 ; rhachis mostly elongated : pe- 

 duncles 1 — several-floioered, bracteate at the summit or sometimes naked : claws of 

 the petals not exserted from the calyx. 



+- Perennials : flowers rather large : umbels 3 — B-fl-owered. 



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

 less appressed silky-pubescent : leaflets 5 to 7, on an elongated rhachis, obovate to 

 oblanceolate, 6 to 9 lines long, acutish : peduncles elongated : umbel 3 — 8-flowered, 

 usually subtended 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, the subu- 

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

 Linn. Soc. xvii. 366. H. ochroleuca, Nutt. 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 equalling 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. S. puberula, Benth., with linear or oblanceolate leaflets 

 upon a more developed rhachis, and H. Wrightii, 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 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 perhaps also by Bigelow on Bill Williams River. It may be distinct. 



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

 ■*+ Peduncles mostly 2 — 5-flowered : standard remote from the wings. 



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 equalling the leaves : umbel usually subtended 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. — Ton'. & Gray, Fl. i. 326. 



Near the sea, from Santa Barbara to Los Angeles. 



++ ++ Peduncles 1 - 2-flowered, aboid equalling the leaves : petals all approximate. 



1 1 . H. Strigosa, Kutt. 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 wings ; 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, Uutt. 1. c. 



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

 rado River. Very variable. 



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

 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. 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.
