Rubus linkianus, Ser. St. angled with many very strong and sharp hooked prickles and mostly finely pubescent: petioles and midribs strongly prickly; lfts. 3-5, oval or elliptic and acute, strongly and mostly doubly toothed, green and nearly or quite glabrous above but white-tomentose beneath: infl. short-paniculate, beset with strong prickles and often more or less leafy, pubescent or tomentose: fls. mostly double, white, the petals obovate and about 1/3-1/2in. long: fr. black.—Species founded on garden specimens, the native country being unknown. It is said to be sometimes escaped from cult. and occurs now and then on ballast. A similar plant (not double-fid.) occurs under apparently feral conditions from Md. to Fla., and from this race the Tree blackberry or Topsy, a very thorny variety intro. some years ago as a fr.-plant, seems to have come. This American plant has been confused with R. cuneifolius, but differs in its very different foliage. This group is much in need of careful study; Focke regards it as one of the forms of R. thyrsanthus. The plant sometimes grown as R. fruticosus flore alboplena and R. spectabilis, Hort. (not Pursh), probably belongs here or with the following.
