Hybanthus concolor (T. F. Forst.) Spreng.
Common Name: GREEN VIOLET
Coefficient of Conservatism: 9
Coefficient of Wetness: 3
Wetness Index: FACU
Physiognomy: Nt P-Forb
Status: SC

Rich mesic forests to swamps, including floodplains and river banks.

The small greenish flowers grow 1–3 in the axils of the middle leaves, and are pendulous. These rarely set fruit. As noted first by Emma Cole (1898), cleistogamous flowers develop in the axils of the upper leaves later in the summer. Those flowers do regularly set fruit, so one may see plants in the fall with only a few capsules, these all from the upper most nodes.
