(640.) Franseria tenuifolia, Gray $■ Harv. in PL 

 Fendl. p. 80; var. tripinnatifida : segmentis foliorum cre- 

 bris brevioribus. — Mountain prairies of the Liano, along the 

 margin of thickets. November. — This pretty clearly belongs 

 to the same species as the plant which Fendler collected at 

 Santa Fe; but all the lower leaves are tripinnately parted, 

 their segments shorter and broader ; and only the upper 

 bipinnately parted leaves have the terminal lobes prolonged. 

 The fertile involucre, in the specimens examined, is only one- 

 celled and one-flowered ; and so it sometime* is in Fendler's 

 specimen. It is, like that, minutely scabrous-pubescent, and 

 the spines, which are more developed and more numerous 

 than in Fendler's plant, but much shorter than in F. Hoolce- 

 riana, all have uncinate points.
