SOAIE UXDESCRIBED PLANTS FROM SOUTHERN 



CALIFORNIA. 



By I. M. Johnston. 



upinus elatus Johnston, sp. nov. 



Perennial ; plant consisting of a cluster of several erect, 

 slender, herbaceous stems ; stems striated, covered with a minute 

 appressed silvery-silk pubescence, well branched above the middle, 

 6-9 dm. high ; leaves silvery-sericeous, the under surface not so 

 densely so as the upper ; leaflets 5-8, narrowly oblanceolate, acute, 

 3-8 cm. long, 2^-8 mm. wide; petioles ly2-4 cm. long; stipules 

 5 mm. long, deciduous, setaceous ; racemes loose, few flowered, 

 less than a dm. long ; peduncles usually shorter than the racemes ; 

 flowers rather small, verticellate or scattered ; pedicels 2-3 mm. 

 long ; bracts 4 mm. long, early deciduous ; calyx sericeous, gib- 

 bose, its upper lip notched, 6-7 mm. long, the lower lip nearly 

 entire, 4-5 mm. long; corolla light blue, 8-10 mm. long; banner, 

 wing and keel of equal length, glabrous ; pods pubescent, 2-3 cm. 

 long, 6-8 mm. wide, 2-5 seeded, obliquely sharp pointed ; seeds 

 mottled with dark brown, 3-4 mm. in diameter. 



In habits and gross characters this plant is nearest to Lupinus 

 laxifloriis Doug. It can be separated from that species by its 

 pubescence, its glabrous flower-parts, its longer leaflets, its shorter 

 pedicels and peduncles, its taller growth and by it more branching 

 habit. 



The only Southern California lupine which could be. con- 

 fused with Lupinus elatus, is L. formosus Greene. It is readily 

 separated from that species by its erect and taller growth, its dif- 

 ferent pubescence and by its much larger leaves. 



The type of this species, our No. 1627, was collected July 30, 

 1917, at 8,000 ft. alt., LTpper Transition Zone, near the head of 

 Icehouse Canon, San Antonio Mts. The type is in the authors 

 herbarium. Cotypes are to be found in the Gra}^ Herbarium and 

 in the Pomona College and Stanford University herbariums. 



Hosackia argophylla Gray var. decora Johnston, var. nov. 



Stems more slender and shorter than in the species. Pubes- 

 cence conspicuously less dense, softer and more appressed, in 

 herbarium specimens distinctly silvery, never golden in color. 



This variety is constant and readily recognizable and appears 

 to have a distinct range from the typical plant. H. argophylla, 

 readily recognized by its dense, almost woolly, pubescence, ranges 

 on the dry hot interior area of San Diego and Riverside Counties. 

 Our proposed variety grows in the chaparral and pine belts of 

 the San Jaciento, San Bernardino and San Gabriel Mountains 

 and may extend farther north, since, in some respects, it seems 

 rather close to H. ar gen tea Kell. 



The type, our No 1278, collected July 15, 1917 in Cascade
