68 LABIAT.E. MicROMERiA. 



lobe longest. Stamens all fertile ; the lower pair slightly exserted , the upper shorter : anther- 

 cells oblong, at length widely divaricate. Style almost equally 2-cleft at the summit. 



On calcareous rocks, about the Falls of Niagara ; Goat Island, and on Table Rock. Au- 

 gust. The Cunila glabella of Michaux, which occurs on rocks in Tennessee, diflfers from 

 the Niagara plant in being much larger ; the leaves all ovate- or obovate-oblong, and toothed. 

 I should have described the latter as a distinct species, had I not received some Ohio 

 specimens, collected by Mr. SuUivant, which connect the two forms.
