Park Species Detail: Wiegand, 2001b: False pimpernel (Lindernia dubia) is not so abundant as the previous species [Justicia americana], but it often occurs in the same low, wet habitats along and near the river shoreline. Being small and inconspicuous, it probably goes unnoticed much of the time, and may be more abundant than is currently thought. Found at 1 site.
