No. 22, 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: Ifts usually 3, narrow-ovate to ob- long, 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. usu- ally oblong, some- times excellent but o f t e n e r dry and seedy. From Virginia to Florida and Texas, and in cult, in two or three forms for its fruit.—This is the common Dewberry of the southern states. It is often a-serious pest in old fields. Some of the forms are very distinct, but it seems to be impossible to discover characters by means of which they can be distinguished with even a fair degree of uniformity. Some of these forms have fls. 2 in. across. Fig. 2215 is a drawingof one of the specimens (there are two similar specimens on the sheet) on which Michaux founded M. trivialis.

Forms have been found with canes 40-50 ft. long and nearly an inch in diameter. Group 5. The Western Dewherries, with puhescent Ivs., and fls. often imperfect. 35. vitifdlius, Cham. & Schlecht.
