Vincentoxicum macrophyllum is
a perennial herb that inhabits moist deciduous tree forests, with
stems growing to 0.5-1m in height and the stem tops extending
outward in a climbing manner. Leaves are of opposite phyllotaxis in
some pairs, have a thin texture, are in the shape of a broad oblong,
and are 12-25cm long. The leaves on the upper parts of the stems
abruptly become smaller, and cymose inflorescences emerge from those
leaf axils. The flower stalks are long, 2-5cm in length. Flowers are
dark purple, 8-10mm in diameter, with white, frizzled hairs on the
inside. Follicles, or a dehiscent fruit, are significantly more
prominent than the flowers, 5-8cm long. Bloom time June-August. |
