1919J Hall: ChrysothcDinius ^aiisfosus (uid lis Vnrictirs 175 



As here restricted, calif ornicus is a rare siib-shriib oi' the high 

 Sierra Nevada. Oiir description is drawn from Bolander's no. 6137 

 from Mono Pass at 9000 to 10,000 feet altitude. In the original 

 description Greene combined with this a taller form with tomentulose 

 leaves and inflorescence and 5-fiowered he.ads, which form belongs to 

 lower altitudes and is included in speciosus of the present synopsis. 



16. Chrysothamnus nauseosus var. ceruminosus (l)ur. & Ililg.) 



comb. nov. 



Liiiosiiru'i (■( ) uiniiiosd J)iir. & Hilg., Pac. R. Rept., vol. ."), part iS. p. 9, 

 pi. 6, 1836. 



Shrub 5 to 12 dm. high, fastigiately branched, the stems yellowish 

 green with a compact tomentum : leaves linear-filiform, 1 to 3 cm. 

 long, tomentulose : inflorescence compactl.y cymose, rounded, 2 to 3 cm. 

 across: involucre 7 to 8 mm. high; bracts thin, yellowish, abruptly 

 narrowed to a filiform recurved mucro about 1 mm. long, glabrous 

 and glutinous or apparently somewhat puberulent : corolla about 6.5 

 mm. long; lobes 1 to 1.7 mm. long. 



Known from oul}' two collections, namely, the type collection by 

 Dr. Heermann somewhere near Tejon Pass, California, and one made 

 by Mrs. Spencer in October, 1917, at Hesperia, a station on the Mojave 

 Desert about ninety miles east of Tejon Pass. 



17. Chrysothamnus nauseosus vai-. creophilus (A. Nels.) comb. nnv. 



Chrysotliamiius orcophilus A. Ncls., Bot. Gaz., vol. 28, p. 'M'k 1899. 



Shrub described as 2 to 4 dm. high with erect stems, very leafy 

 to the top : twigs .yellowish green, the tomentum thin and smooth : 

 leaves 3 to 7 cm. long, about 1 mm. wide, strictly erect, the upper 

 ones crowded and not reduced, all tomentulose at least when young- 

 but green : inflorescence composed of numerous small cymes in a more 

 or less elongated but round-topped thyrse : involucre 7 to 8 mm. high ; 

 bracts carinate, acute, sparingly tomentulose, ciliolate : corolla 7 to 

 10 mm. long; tube crisp-pubescent; lobes linear-lanceolate, 1.3 to 

 2 mm. long. 



This is an apparently rare plant of saline soils in Wyoming 

 and Idaho. Its characters indicate that it may be a derivative of 

 graveolens differing chiefly in the narrower leaves and much longer 

 corolla-lobes. In the latter respect it resembles consi))uIis, into which 

 more westerly form it probably intergrades. The more numerous and 

 wider strictly erect upper leaves and the somewhat flat ciliate bracts 

 may, however, serve to distinguish it from co)islniiIis.
