VIRGINIA PLANTS, 
During the present spring and summer I shall collect along the south- 
ern boundary of Virginia, from the coast to the mountains, a region un- 
explored botanically, and one that will beyond a doubt yield a number 
of new and many rare plants. An endeavor will also be made to obtain 
all the new species, about a dozen in all, collected by myself and others 
during the past three years in adjacent territory. An effort will be made 
not only to keep up the standard of previous collections, but also to m= 
prove upon them in every way possible. Anyone desiring sets, shoul 
please address
