Rosa sambucina is
a deciduous shrub (semi-vine) found in forests in hilly districts,
climbing a cliff, or something with hook-shaped thorns. Leave are of
alternate phyllotaxis, each of an 11-15cm-in-length imparipinnate
compound leaf; leaflets, 2 or 3 pairs, 5-10cm-long long-oblong or
oblong, tips sharply pointed, having keen serrations on the margins.
Terminal leaflets are more significant than the others. Branch tops
bear bundles of 10-20 5-petaled white flowers, each large measuring
4-5cm in diameter. Bloom time: May-June.
