R. californica C. & S. California Rose. Stout, 3 to 6 feet high; prickles few or numerous, mostly stout and recurved, or sometimes straight, usually also with one or a pair below the stipules; flowers few to many; hips globose or ovoid.
Common everywhere on moist valley floors, along river and creek banks and margins of springs, often forming small thickets, 1 to 4000 feet; throughout cismontane California.
May - Nov., flowering most freely in June.
Note on variation.--Rosa californica is a variable complex which has been segregated by various authors...All of these segregates are about equally untenable....It is believed, however, that the group represents a "hybrid swarm" and that the occasional outstanding specimens result from chance combinations of the independently varying characters of an interbreeding population.
