 otherwise closely resembling H. oblongifolia from which it is probably not specifically distinct. Originally col- 

 lected at Fort Miller on the banks of the San Joaquin River, and ranging to southern California.

 peduncles filiform, shorter than the leaves; bract when present 1-foliolate, flowers 1 or 2; calyx 

 glabrous, the teeth subulate ; petals 5-7 mm. long, yellow, turning copper-colored in age. 



Wet meadows, Canadian Zones; southern Sierra Nevada, California. Type locality: Hockett Meadows, 

 altitude 8,600 feet, Tulare County. June-Aug.

Hosackia grandiflora Benth. Trans. Linn. Soc. 17: 266. 1837.

 Lotus grandiflorus Greene, Pittonia 2: 145. 1890. 

 Anisolotus grandiflorus Heller, Muhlenbergia 8: 20. 1912. 



Perennial from a deep-seated woody root, the stems simple or branched, erect, 2-7 dm. high, 

 whole plant pubescent with upwardly appressed incurved hairs. Leaflets mostly 7 or 9, obovate 

 to elliptical, 1-2 cm. long; peduncles 4-8 cm. long; bract 1-foliolate, subtending the umbel, 

 sometimes absent; umbel two- to several-flowered; calyx-tube 5 mm. long about equaled by the 

 subulate teeth ; petals yellow, turning rose in age, about 2 cm. long, the claws included in the 

 calyx ; pods 3-4 cm. long, 2 mm. wide ; seeds broadly and somewhat obliquely ovoid, about 2 mm. 

 long, dark brown. 



Open woods. Upper Sonoran Zone; western slopes of the Sierra Nevada and the Santa Ynez Mountains, 

 Santa Barbara County, California. Type locality: California, collected by Douglas, probably in the vicinity of 

 Santa Barbara. April-June. The Sierra plants, which represent H. macrantha Greene, have larger flowers than 

 the Santa Barbara plants. 



11. Hosackia leucophaea (Greene) Abrams. Pale Hosackia. Fig. 2720. 



Hosackia grandiflora var. anthylloides A. Gray, Proc. Acad. Phila. 15: 350. 1863.

Lotus grandiflorus var. mutabilis Ottley, Univ. Calif. Pub. Bot. 10: 208. 1923. 



Closely related to H. grandiflora, and distinguished mainly by the more compact habit and 

 shorter stems, which arise from slender widely branching rhizomes ; whole plant pale glaucous 

 green and more or less densely villous with spreading hairs. 



Dry ridges, mainly Arid Transition Zone; Coast Ranges, California, from Mendocino County to the Cuya- 

 maca Mountains, San Diego County. Type locality: Santa Lucia Mountains, Monterey County, California.
