With approximately 1m tall, 4-ridged stems,
Hypericum ascyron,
a perennial herb, grows in damp grasslands or swamp fringes in
mountainous regions. Leaves are of opposite phyllotaxis, in the
lanceolate shape, 4-10cm in length, and the basal portions embrace
the stems to some extent. Pale glands exist on the leaf surfaces,
but no dark ones do. The stems branch at the top and produce yellow
flowers that bloom for a day on the branch tips. The flower is
5-petaled, with each petal 4-6cm in length. The sepals are 6 in
number, each differing in size, and have many pale glands between
their veins. Bloom time: July-August. |
