1902] ROCKY MOUNTAIN PLANTS 31 



in fruit: corolla yellow, very moderately bilabiate, nearly tubu- 

 lar, 5-8"^'" long : capsule not stipitate, elliptic, obtuse, nearly 

 equaling the slender style which barely protrudes from the 

 mature calyx: seeds nearly oval, very small. 



This is the counterpart in this range of M. ahinoides Benth. of the 

 Washington-Oregon flora. From that species M.membnmaceus differs prin- 

 cipally in the enlarged and angled calyx, the scarcely bilabiate corolla 



(without the purple spot on the lip), and in the obtuse capsule and orbicular 

 seeds. 



Of the three collections of this all were secured in the Medicine bow 

 mountains, always growing more or less in the shade of wet rock ledges and 

 cliffs; nos. 1515(1895); 1683 (1895), type ; and 7729(1900). 



MiMULUS Lewisii tetonensis, n. var. — Smaller than the 

 species in every way, more granular-glandular: calyx lobes 



shorter, narrowly linear-acuminate: corolla shorter, white or 

 tinged with yellow. 



Collected by Elmer D. Merrill and E.N. Wilcox in the Tetons. Wyoming, 

 at 1 1 ,000 ft., near Lee's lake, July 26, 1901 ; no. 1072. 



Pentstemon comarrhenus Gray — I wish to call attention to 

 the ^I'^X^WizX.n^ssoiP.comarrhemis Gray (Proc, Am. Acad. 12:81) 

 and P, strictus Benth. (DC. Prod. 10:324). P. strictiis in Gray 

 Syn. PL 2: 262 seems to include both, though probably referring 

 mainly to the plant of Utah and western Colorado. P. stricttis 

 was founded upon immature specimens collected by Fremont on 

 the Platte river in Wyoming, where it is abundant, though appar- 

 ently not again collected until within the last few years, hence 

 the confusion. Good specimens of the two species wdien com- 

 pared leave no doubt as to the validity of both. Typical speci- 

 mens of P. strictus are my nos. 1472, 1579, 3079, and others from 

 Wyoming and adjacent Colorado. Of the other species Mr. M.

^ This description and the notes upon it were written before I discovered Dr. 

 Rydberg's PePUsiemon suffrtitescens. Bull. Torr. Bot. Club 28 : 503. From the very 

 "niited notes there given I judge that he and I are considering totally different 

 plants. As I feel quite certain that I have the true P. caespitosus suffrulicosus Gray, I 

 still present this description, if I be right, Dr. Rydberg's P. suffrutescens is practi- 

 cally a nomen nudum until he presents a description of it.
