Rubus trivialis, Michx. Southern Dewberry. A variable and perplexing species, the difficulties being increased by the fact that the same plant may bear 3 kinds of lvs.: the large, broad blackberry-like lvs. on the young verdurous sterile shoots; the smaller lvs. on the canes that are to bear fr. and which often persist over winter and remain at flowering-time; the small lvs. that appear with or somewhat before the fls. It is seldom that the lvs. of sterile and flowering shoots of the same plant are preserved in herbaria. Canes very long, usually wholly prostrate (sometimes 10-15 ft.), thickly armed with prickles and sometimes bearing reddish bristles: lfts. usually 3, narrow-ovate to oblong, short-pointed, rather shallowly and sometimes bluntly toothed, the petiole and midribs usually prickly: fls. of medium size, mostly on simple, more or less prickly peduncles: fr. usually oblong, sometimes excellent but oftener dry and seedy. From Va. to Fla. and Texas, and in cult. in two or three forms for its fr.—This is the common wild dewberry or running blackberry of the southern states, often a serious pest in old fields, ranging as far north as Va. and west to Okla. What are apparently forms of this species have been intro. for cult. for the fr. in the southern states.
