this plant, apparently rare, has become epidemic, being found suc- 
cessively at Mt. Carmel, IIl.; Hanover, Ind.; Cincinnati, Ohio; 
Roanoke and Eggelston’s, Va.; Wall, Pa.; Franklin Co., Ohio; | 
Marion, Va.; Knoxville, Tenn. ; the Cumberland Mountains, Ky., 
and Caldwell Co., N.C. I have searched carefully through the 
books containing references to the genus Oxalis and compared 
descriptions and plates. Nothing in them seems to correspond to 
the plant in question, and, as far as I can learn, it never has received | 
a name except that given to it erroneously. Oxalis grandis isa 
name that will serve to designate its size and the stately habit it 
assumes in growing. 
The two species are so very dissimilar that no detailed account 
of their respective characters is necessary, but descriptions and 
plates are added, which will serve to show the great contrasts be- 
tween them. - As mentioned. above, the geographical ranges are 
remarkably well defined, and a map is also given, on which the 
stations and ranges are plotted as they are now known. The Taner 
of O. vecurva lies mainly to the east of the Allegheny Mountains, . 
while that of O. grandis is for the most part west. The two ranges 
meet on the mountains at the Roanoke and Marion stations 12 — 
Virginia. At present, then, we have two beautifully contrasted 
geographical areas for the two species under consideration, but as 
exploration goes on, in and about the mountains, we may expect 
to find more or less over-lapping of the two ranges.
