SPECIES OF MIMUIvUS. 7 



M. PETiOLARis. Perennial, upright, rather slender, more 

 than a foot high, glabrous except as to upper part of inflores- 

 ence, all the foliage elongated and rather long-petiolate, only 

 the floral bracts sessile : leaves 3 to 5 inches long including 

 the petiole, blades oval to lanceolate, mostly tapering to the 

 petiole, acutish or obtuse, saliently and doubly dentate : raceme 

 simple, lax, pedicels slender, elongated : corollas smallish, % 

 inch long, yellow : mature calyx unknown. 



Argus Mountains, Inyo Co., Calif., Apr., 1891. Coville & 

 Funston, n. 740 as in U. S. Herb. Remarkable for long narrow 

 long-stalked leaves. 



M. VERONiciFOLius. Middle-sized perrennial species, sub- 

 erect from a decumbent base, sparingly leafy, glabrous as to 

 the basal parts, at summit minutely puberulent : lowest leaves 

 obovate, petiolate, the upper sessile, ovate, all serrate-dentate : 

 flowers mostly 2 only, occasionally but one, large, long-pedi- 

 cellate ; calyx-teeth very unequal, the upper very large, obtuse ; 

 corolla very large, yellow. 



At 5,000 feet in the Olympic Mountains, Washington, C. V. 

 Piper, Aug., 1895 ; n. 2177 as in my herbarium. 



Of the group of the tufted alpine, perennial, to which the 

 Californian M. implexus belongs ; differing from that by its 

 veronica-like foliage and excessively large corollas, these 2 

 inches long and nearly IJ^ inches wide at the orifice. They 

 are perhaps the largest in the genus. 



M. LUCENS. Akin to M. implexus, differing by much more 

 slender stems which are weak and decumbent ; leaves exactly 

 ovate, truncate or subcordate at base, of such delicately succu- 

 lent texture as to be clearly translucent when dried under 

 pressure : calyx sparsely and finely villous. 



Along rivulets in deep woods of the Powder River Moun- 

 tains, Oregon, C. V. Piper, Aug., 1896, nn. 2518, 2519 as in 

 my herbarium. 



I myself once identified this for Mr. Piper as M. implexus, 

 but that was done too inconsiderately. It is as large a plant, 

 but of a totally different anatomy, its herbage, though fleshy.
