Lycopus lucidus is a perennial of about 1m tall herb
growing in wetlands with white rhizomes. Stems are thick, with nodes
with some white hairs, and the whole, exclusive of the nodes, are
glabrous. Leaves densely alternate themselves, 6-13cm long, 1.5-4cm
wide, broadly lanceolate, with coarse serrations on margins. Axils
generate many orderly small white labiate flowers. Corollas measure
about 5mm long, and lower lips are more significant than the lowers.
Calyxes are cleft halfway in five, and the lobes are spiny with
sharply pointed tips. Stamens are 2 in number. Bloom time:
August-October. |
