Polygonatum
macranthum is a perennial herb of approximately 1m in height,
inhabiting forests in mountainous regions. Its cylindrical stems,
measuring 60-140cm in length and lacking ridges, are smooth, and as
they reach the upper half, they curve gracefully into a bow. Leaves
are of two-row alternate phyllotaxis, 15-17cm long, in the shape of
a lanceolate to long-oblong, with entire margins and short petioles.
Flowers droop downward; single at upper parts and 2-4 in corymbs at
lower positions. The flowers are white, 2.5-3.8cm long,
funnel-bell-shaped, with green tips, and the corolla's segments are
warped. Sap fruit is 0.8-1.2cm in diameter and spherical. Bloom
time: May-July. |
