Plants 0.6 to 2 meters high, herbaceous or suffrutescent, the stems densely 

 pilose; leaves lance-oblong or oblong-ovate, 4 to 8 cm. long, acuminate, ser- 

 rulate, tomentulose beneath ; spikes very dense, villous ; corolla purplish. 



Cunila stachyoides was described from Orizaba. 



2. Cunila longiflora A. Gray, Proc. Amer. Acad. 22: 444. 1887.

The writer has seen no specimens of C. secunda S. Wats.,' which was de- 

 scribed from Guanajuato, where it is said to be known as " poleo de cerro." 

 From the description it can not be distinguished from C. longiflora, and prob- 

 ably Watson's name sliould replace C. longiflora.
