Cruz^ Sonera; Wright (1200, male). Puerto de Paysano ; Bigeloio (both sexes). Oak woods 



between Babocomori and Santa Cruz ; Thurhcr. The additional specimens, of both sexes, show 



this to be clearly different from the preceding, and probably an unpublished species. The 



leaves in Dr. Bigelow's specimens, from which the character is principally taken, are much 



broader than in Wright's or Thurber's, more irregularly toothed or incised, and all obtuse^ 



while those of Wiight's are lanceolate or linear lanceolate, and often acute.

 Mr. Wright and Dr. Gregg collected only the male plant, apparently the same with that pub- 

 lished by De Candolle from Keerl's Mexican collection. The fertile plant now being known, 

 the plant is found to be a genuine Baccharis. Berlandier likewise collected specimens in the 

 mountains of San Luis Potosi (No. 1352.)
