Vincentoxicum macrophyllum is
a perennial herb inhabiting moist deciduous tree forests, with stems
growing to 0.5-1m in height and the stem tops reaching out in a
climber way. Leaves are of opposite phyllotaxis of 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, dark purple,
8-10mm in diameter, have white frizzled hairs on the insides.
Follicles, or a dehiscent fruit, are significantly more prominent
than the flowers, 5-8cm long. Bloom time June-August. |
