flowering time : herbage scabrous with a short rigid pubescence, 

 the stems sometimes almost glabrous : leaves rigidly erect or 

 ascending, narowly lanceolate, sessile by a broad subcordate base, 

 acute, remotely serrate or entire, the larger 7 or 8 cm. long by 1 

 cm. wide : inflorescence commonly a close raceme ; the rigid erect 

 peduncles very short, clothed with small linear bracts : involucre 6 

 mm. high, its bracts with obtuse or merely acutish tips : rays 

 "violet or purple," 6 mm. long. (Plate 1.)

5. A. defoliatus Parish, Bot. Gaz. xxxviii. 461 (1904). 

 Slender but rigid, about 1 m. high, divaricately much 



branched above, leafless when mature except on the flowering 

 branches: herbage minutely pubescent or the older parts 

 glabrous: lower leaves not known; upper cauline leaves narrow 

 and apparently linear, but only basal fragments seen; leaves of 

 the branchlets linear, acute, rigid, 1 cm. or less long, less than 1 

 mm. wide: heads solitary or 2 to 4 together terminating the 

 branchlets the lower of which are often 15 cm. long while the 

 upper are much shortened; the whole inflorescence thus appear- 

 ing as a very loose panicle : involucre 6 mm. high, its bracts with 

 broad scarious margins below: "rays about 40, light violet" 

 (Parish) : style-appendages lanceolate-acuminate. 



Known only from the original collection; in a meadow at 

 San Bernardino, Oct. 17, 1903, Parish, no. 5335. 



6. A. Bernardinus Hall, sp. nov. 



Plant 4 to 8 dm. high : stems several from a perennial base,

 herbage conspicuously cinereous with a dense short and very soft 

 pubescence : leaves loosely spreading or reflexed, linear to linear- 

 lanceolate, 3 to 5 cm. long by 3 to 5 (rarely 7) mm. wide, those 

 of the branchlets much smaller- heads in short or elongated
