Cleistesiopsis oricamporum P.M. Brown
Cleistesiopsis oricamporum is a recently described species of the southeastern Atlantic and Gulf Coastal Plains. The Virginia population discovered in 2017 represents a new northern range limit, slightly disjunct from southeastern North Carolina populations. This species is closely related to the montane C. bifaria, but differs in its vanilla-scented flowers (vs. non-scented in C. bifaria) and perhaps in some minor morphological characters. DNA studies strongly suggest that the two species are distinct., but their precise geographic distribution requires further study through wider DNA sampling, especially in the Atlantic states (K. B. Gregg, pers. comm.). The Virginia population occurs on a wet, open seepage slope within a formerly fire-maintained longleaf pine area; it co-occurs with the larger Cleistesiopsis divaricata and several other Coastal Plain state rarities (e.g., Gentiana autumnalis, Lilium catesbaei) known to be associated with C. oricamporum further south.
In boggy powerline right-of-way through seasonally saturated (former longleaf pine) flatwoods; known from a single site in Suffolk City. Rare, se. Coastal Plain.
