throat but slightly dilated; the short lobes (3-4 mm.) abruptly 

 reniformly expanded: anthers linear-oblong; filament inserted at 

 the summit of the tube proper, as broad as the anther but only half 

 as long, the two together as long as the throat: nutlets smooth or 

 nearly so. 



This seems to be an unusually strong species. Carelessly examined it 

 might be referred to M. ciliata, but in reality it is closer to M. Macdougallii 

 Rydb., of Arizona, from which it is clearly distinct and is equally distinct from 

 M . Leonardi Rydb. Its calyx is distinctive in this genus. 



Mr. C. N. Woods, supervisor of the Sawtooth National Forest, secured it 

 in moderately moist meadows" and sent in the ample specimens, at the same 



time calling attention to its salient characters. No. 325, Blaine County, 

 Idaho, 191 1.
