Rosa multiflora is an exotic rose that has escaped cultivation. It has large clusters of small whitish to pinkish flowers
on a rather large plant, growing over 6 feet tall with arching stems armed with stout prickles. The best distinguishing feature
of Rosa multiflora are the deeply fringed and stipitate glandular stipules (structures at the base of the petiole). The
hip is also notable for being narrowed toward the apex. Rosa multiflora has so far only been found at the roadside in the Mangas Springs
area.
Many thanks to Mark Widrlechner and Bill Norris for letting me know where to find this plant.
