The following determinations of the Compositce of Dr. Palmer's 

 collection are by Dr. Gray. For his descriptions of the new species, 

 and for other notes, reference is made to a subsequent article in this 

 volume.

 erland Springs, Texas (751).

 Luis Potosi (347 Schaffner).

 Saltillo (430). 



Eupatorium azureum, DC. At Guajuco (434), and Monterey, 

 Nuevo Leon (437, 438) ; 341 Parry & Palmer. The Monterey spe- 

 cimens, like those of Gregg's early collection (52), exactly match 

 1380 Berlandier, upon which E. azureum was founded. Upon Ber- 

 landier's ticket in herb. DC. *' flores azurei " is written, hence the 

 specific name. But Gregg noted the flowers as " purplish," and 

 Palmer (upon the Guajuco specimen, which is evidently a form of the 

 same) as " creamy white." 



Eupatorium altissimum, Linn. At Lamar, on Copano Bay, 

 Texas (435).
