Smilax nipponica, a
perennial herb found in fields and mountains, has erect stems, and
then the upper parts become vine-like and twine around. Leaves are
of alternate phyllotaxis, 4-20cm long, in the shape of an oblong,
with surfaces that are not glossy and have a thin texture. Tendrils
emerge from axils. Both male and female flowers, 6-petalled,
yellow-green, set themselves in umbels that arise from axils;
perianth lobes do not bend back. Bloom time: May-June. |
