198 ECONOMIC BOTANY OF ALABAMA 



fruit with fewer and larger drupelets, a little juicier and otherwise 

 better than that of most of the blackberries. 



Where this grew a few centuries ago is a mystery, for it seems 

 to be confined now to habitats considerably altered by civilization, 

 such as old fields and roadsides. It is widely distributed over the 

 state, apparently most common in the central portions, and com- 

 paratively rare in the long-leaf pine regions, though it extends to 

 the shores of Mobile Bay. 



Rubus hispidus, L. (Swamp Dewberry.) 



A small evergreen vine, with fruit scarce and practically 



tasteless. 



Native in damp woods. Reported from Lookout Mountain 



and Lee County by Dr. Mohr ; but according to Prof. Earle the 



latter record is an error. 



Rubus occidentalis, L. 



Black-cap Raspberry. Thimble-berry. 



A neat shrub with few prickles ; the stems and under surfaces 

 of the leaves waxy. Blooms in April, fruit ripe in June. 



Grows in rocky woods ; rare in Alabama but common farther 

 north. 



IB. On limestone near Scottsboro, Jackson County. Warnock Moun- 

 tain, Blount County. . ,, ,. ^ 



IC. On sandstone on Smithers Mountain, Madison Lounty. 



2 A. On Monte Sano and Lookout Mountain, at elevations above L^UU 

 feet (Mohr). 



Rubu<; odoratus, L.. the flowing raspberry, a handsome northern species 

 with simple leaves, large pink-purple flowers, and worthless fruit is cred- 

 ited to Alabama by Small, but without definite locality and probably with- 

 out sufficient evidence. 



ROSA, Linnaeus. The RosEs. 



Another puzzling genus, especially in the North and in Eu- 

 rope, where it is represented by innumerable cultivated forms, 

 mostly double-flowered, and a few single-flowered species that 

 are native or have escaped from cultivation. Only about three 

 native species are known in Alabama, and about the same number 

 of introduced ones.
