thought that all the Strawherries of the five parts of 

 the world, formed only one species, the actual one. 

 Others have thought otherwise and attempted to dis- 

 tinguish several species and varieties, among those 

 found in America, Africa, Asia and Polynesia; hut 

 the difficulty has been to ascertain (as among the 

 Roses) which are the specific or constant forms and 

 which are variable deviations. 



If every deviation of form, color, direction, pubes- 

 cence and composition, was to he considered specific, 

 we should have 100 kinds of Strawberries, and indeed 

 some gardeners have described thirty or forty kinds, 

 while more accurate botanists only acknowledge ten 

 to fifteen species as yet. Meantime these species have 

 all the same habit and flowers, differing only by some 



inconspicuous details. 



Our wild Strawberry was long thought the F. vescdy 

 until Wildenow and Pursh made two new species of 

 it. In attending to the many varieties which I have 

 seen in my travels, I thought that three or four more 

 species could be made from them ; but noticing that 

 they are all connected by intermediate links, I came 

 to the conclusion that they were only varieties of the 

 /*. vescay and that the whole genus requires a revision. 

 I could mention about twenty varieties of our wild 

 Strawberries and seventeen from our gardens; but 

 shall confine myself to seven of the most remarkable 



native kinds. 



1. Var. Uniflora, stems simple, one flowered, one 

 leaved, as long as the radical leaves, folioles sessile, 

 Buboval, incise-serrate ; calix spreading or erect, pe-
