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, thin
texture, in the shape of a broad oblong, 12-25cm in length. 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 insides. Follicles, or a
dehiscent fruit, are significantly more prominent than the flowers,
5-8cm in length. Bloom time June-August. |
