east of the Mississippi, but ranges from Minnesota to Sonora. 

 The widely distributed plant of the Pacific Coast, also mixed up 

 with Lotus Americajius, appears to me quite distinct, as Nuttall 

 made out, describing it as Hosackia data (In T. & G. Fl. N. A. 

 i. 327) and there may be, as he also thought, several other 

 closely related species in California and the Northwest. 



Psoralea Reverchoni, S. Wats., Proc. Amer. Acad. xxi. 449, 

 originally described from specimens collected by Mr. ReverclK n 

 in western Texas, in 1877, was also found by Dr. Palmer in 

 the Indian Territory, 1868 (No. 72). 



Psoralea corylifolia, L. is in Dr. Chapman's Herbarium, 

 ticketed " Appalachicola, introduced." It is an Asiatic species, 

 close to P. dentata, DC. of southern Europe. 



Cassia crotolai'ioides, Kunth, var. lencopJiylla, Benth. There 

 is a specimen so determined in the Kew Herbarium, collected by 

 Prof. Mosely in the Grand Canon, Colorado Plateau, Arizona, 

 1884. The species is known in north Mexico, and its occurrence 

 in this region might have been expected. 



Ilex rnontana, T. and G. var. MOLLIS (A. Gray). Ilex mollis, 

 A. Gray, Man. Ed. 2. Leaves as in the type, but pubescent be 

 neath. Burgoon's Gap, Penn. (Porter). Pocono Plateau, Penn., 

 collected by myself on the Torrey Club Field Excursion, June 

 7-10, 1889. 



This plant was first referred to Ilex diibia (Don.), B. S. P. 

 Prel. Cat. N. Y., but on comparison with typical specimens of 

 this species from the Alleghanies of North Carolina, Georgia and 

 Alabama, it appears hardly possible that this disposition of it is 

 correct. /. diibia has broadly ovate, oval or even obovate leaves, 

 which are rarely acuminate and commonly obtuse, and are much 

 more densely and softly pubescent beneath. 



Ilex mollis was founded on the Pennsylvania plant, and the 

 southern species subsequently referred to it. I am maintaining 

 dubia as the specific name of the latter on the authority of Dr. 

 Gray, who probably saw a type of it. But from Don's descrip- 

 tion o{ Prinos dtibius, (Gard. Diet. ii. 20), this would not be certain, 

 and he says it occurs from New Jersey to Carolina, while the plant 

 which I know as dubia is not reported north of North Carolina.
