 Nutt. ill Trans. Amer. PhiL Soc. 7. j). 3B7, non DC. San Luis Rev, California; Parry. The 

 speciraen accords with No, 305 of Wright's N. Mexican collection, and is, I doubt not, merely 

 a narrow form of B. coerulescons, DC. But it is Nuttall's B. Pingnva, which is wrongly ad- 

 duced as a svnonym of B. Duuglasii in Torr dt Gray^ FL N. Am. 2, j). 250, the real B.

 squamis glabris appressis coriaceis obtusis, exterioribus ovatis, intimis linearibus; acheniis gla- 



berrimis. — Very common on the Gila; Emory ^ coll. in 1846^ etc. Fort Yuma, E. California; 

 Major Thomas. Sterile plant not seen. Involucre of fertile flowers 3 or 4 lines long ; the thick

Bacchaeis ptar^iicjefolia, DC, Prodr. 5, j>. 419 ; Schullz, in BoL Herald^ p. 303. Hill sides 

 between Babocomori and Santa Cruz, Sonora ; Wright (1201). This is the same as Seemann's 

 plant from the Sierra Madre, and, except in the smaller leaves and heads, accords very well 

 with a specimen from the valley of Mexico, collected by Schaffner, and named B. ptarmicsefolia 

 by Dr. Schultz. It accords still better^ perhaps, with the character of B, thesioides^ to which 

 De Candolle's species and all these specimens are probably to be referred.
