Abstract:
Rosa hirtula (Regel) Nakai, a species endemic to Japan, is illustrated. It occurs in central Honshū around Mt. Fuji and Hakone and vicinity. Rosa hirtula is similar to R. roxburghii Tratt., particularly to the single‐flowered form, f. normalis Rehder & E. H. Wils., and is distinguished by its tree habit, hairy rachis, and lanceolate to narrowly oblong leaflets with acuminate to acuminate‐acute apex, serrulate margins, and hairy midvein on the lower surface.
