clustered at the ends of numerous widely divergent branches, 

 the involucres narrow, of comparatively few and strongly im- 

 bricated bracts. 



Lessingia fastigiata. Plants upright, slender, less than 

 i a foot high, simple up to the middle, there parted fastigiately 



into 3 to 5 suberect branches, these again simple to near the 

 summit, there dividing abruptly into pedunculiform fiorifer- 

 ous branchlets, with heads of flowers mostly glomerate at 

 their ends : leaves of stem and branches oblanceolate to 

 oblong-lanceolate, pungently acute, more or less serrate, 

 white-flocculent on both faces : involucres narrow and few- 

 flowered, subcylindric but with bracts rather numerous and 

 well imbricated, even subsquarrose as to tips, without pubes- 

 cence, but more or less glandular : corollas purple : pappus 

 more or less paleaceous by basal coalescence of the bristles into 

 5 sets. 



Type specimens of this excellent species are in my herba- 

 rium from foothills of the Sierra near Chico, by Mrs. R. M. 

 Austin, 1896. Quite the same, but much too green, is 

 material from North Fork of Feather River, by J. B. Leiberg, 

 in July, 1900. H. P. Chandler's 1503 from Klamath River, 

 I in Humboldt Co., is wath less con6dence referred here. 



Lessingia PAI.EACEA. About 2 feet high, slenderly and 

 loosely paniculate from below the middle ; glabrous and 

 glandless as to stem and numerous branches and branchlets ; 

 leaves oblong, acute, few-toothed or entire, white-flocculent 

 on both faces, those of the many filiform branchlets reduced 

 to minute ovate more or less spreading bracts : involucres 

 solitary at the ends of the many filiform branchlets, sub- 

 turbinate, of numerous very unequal and much imbricated 

 bracts, these obtusish, villous-tomentose except at the tips : 

 flowers few in the head, purple : achenes crowned by about 5 

 subulate-aristiform long paleae instead of bristles. 



Middle Fork of Cottonwood Creek, Fresno Co., 16 Sept. 

 1895, collected by L. F. Ward ; distributed by C. L. Pollard ; 

 type in my own herbarium.
