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

 with Lotus Americanns, 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. 



Psoraka Reverchoui, S. Wats., Proc. Amer. Acad. xxi. 449, 

 originally described from specimens collected by Mr. Reverchon 

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

 the Indian Territory, 1868 (No. 72). 



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



ticketed " Appalachicola, introduced.

It is an Asiatic species, 



There 



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



Cassia crotolarioidcs, Kunth, van kncopliylla, Benth. 

 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. 



Hex montana, T. and G. var. MOLLIS (A. Gray). Ikx mollis, 

 A. Gray, Man. Ed. 2. I-caves as in the type, but pubescent be- 

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

 collected by myself on the Torrey Club Field Excursion, June 



7-10, 1889. 



This plant was first referred to Ikx duhia (Don.). B. S. P. 

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

 this species from the Allcghanics of North Carolina, Georgia and 

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

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

 which are rarely acuminate and commonly obtuse, and are much 

 more densely and softly pubescent beneath. 



Ikx mollis was founded on the Pennsylvania plant, and the 

 southern species subsequently referred to it. I am maintaining 

 dtibia 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 dubi/is, (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.
