OROCHAENACTIS THYSANOCARPHA (Gray) Coville, of the south- 

 ern Sierras is to be looked for in the Tehachapi Mts. It is a 

 slender annual with linear entire leaves, yellowish discoid heads, 

 clavate-obovate achenes, and a deciduous pappus of 8 or 9 spatu- 

 late paleae fimbriate nearly to the base. It has an exact synonym 

 in Bahia Palmeri Wats., Proc. Am. Acad. xxiv. 83 (1889), as 

 already pointed out by Mrs. Brandegee in Zoe v. 142 (1901).
