5. B. brachyphylla Gray, PI. Wright, ii. 83 (1853). 

 Diffusely much branched, 6 to 10 dm. high: stems slender. 



woody at base : herbage scabro-puberulent or smooth : leaves most- 

 ly linear, entire, 1.5 cm. or less long, those on the branchlets much 

 reduced and scale-like: involucre 4 or 5 mm. high, 12 to 15- 

 flowered, somewhat canescent ; bracts oblong-lanceolate or broad- 

 er, acute, with greenish back and scarious margins : achenes 4 or 

 5-nerved: pappus scant, rigid, in fruit 6 mm. long, sordid. 



Southern San Diego Co. to Arizona : Larkins Station, Palmer, 

 no. 149 ; Bradshaw Mts., Arizona, Purpus, no. 8502 ; San Bernar- 

 dino Co., ace. to Gray, but there was probably an error in the 

 label since recent collectors have not found it north of San Diego 

 Co.

 cent, especially the inflorescence : leaves linear or narrowly ob- 

 long, obtuse, narrowed to the base, 2 to 5 cm. long, sharply ser- 

 rate : heads few, paniculate or cymose at the ends of the branches : 

 involucre 5 to 7 mm. high ; bracts linear, acute, with a green 

 midrib and scarious margins : achenes pubescent, obscurely 5-
