|Galium odorata is a
perennial borne in a mountain forest, the stem erecting 20-30cm tall
with a whorl of six to ten leaves around it. This species closely
resembles G. japonica in shape. The difference lies mainly in
the leaf and flower shape; with plate, in G. odorata, it is
oblong, while in G. japonica lanceolate, and with flower, in
the former, the corolla is funnel-shaped, while the other not.
