Discussion

Corema conradii occurs in small, disjunct populations along the Atlantic coastal plain and in the interior uplands of northeastern North America. Seeds are dispersed primarily by ants (P. W. Dunwoodie 1990), and postfire seedling emergence appears to be critical in the life history of the species (C. T. Martine et al. 2005). It is in the Center for Plant Conservation’s National Collection of Endangered Plants.
