Inhabits the Pyrenees, and was found on the Rocky Moun- 

 tains by Drummond, — Torry and Boott. The plant from the 

 Pyrenees has rather smaller spikes and other parts. Schk. refers 

 C. Pyrenaica to his C. spicata ; but C. spicata, Schk., Tab. D, 

 fig. 15, seems to be C. Pyrenaica, Wahl., var. acutissima as 

 given by Persoon, on which the flowers are erect and often chiefly 

 staminate.

 Curtis of Hillsboro', and named from its long period of flovvenng 

 in July and August. Its resemblance to C. graalhma fccnr., 

 was early pointed out by its accurate discoverer, and its difference 

 also noticed, and as finely by Dr. Gray. It belongs in the same 

 poup as C. virescens.
