1. M. primuloides Benth. Perennial by stolons, 1 to 6 in. 

 high, the showy solitary flowers borne on slender erect pedi- 

 cels emerging from a basal cluster of leaves. Leaves elliptic, 

 wedge-shaped, or obovate, usually toothed, either clothed 

 with glistening white hairs or nearly glabrous. Corolla 

 bright yellow, l / 2 to 1 in. long, the lobes alike. 



In moist situations at moderate altitude this Mimulus is 

 quite tall and bears leaves for a distance of several inches up 

 the stem. More commonly, however, the leaves are all in a 

 basal rosette. In the Tuolumne and other high meadows one 

 meets with a very depressed, moss-like form, the leaves only 

 Y A to y 2 in. long and densely covered on the upper surface 

 with long, white hairs. This has been named M. pilosellus 

 Greene. The two forms sometimes grow near each other 

 and intermediates occur, but it is not known whether these
