R. micrantha is known immediately as one of the Sweet Briars by the sweet-scented, viscid brown or translucent glands on leaflets, petioles, stipules, pedicels and sepals. It is separated from R. rubiginosa by its taller climbing habit, more equal prickles, absence of acicles [the much smaller prickles that are interspersed among much larger, stout prickles on the canes of very prickly roses such as R. rugosa], and smaller flowers.
