 one tide.

 ments ; tube of corolla exceeding the calyx : upper lip short : 

 lower one 3-lobed : lateral lobes rounded, very concave : middle 

 one straight, mucrone-fbrmed. I/ . ? H. Native of California. 

 Said to be nearly allied to Bartsia tenmifolia, Pursh. The 

 lower lip of the corolla is quite at variance with the character of 

 the genus, yet the upper lip and habit are the same. At each 

 side of the central lobe of the lower lip is a small gland, as in 

 several other species.
