Name: Isoetes spp. - Pilularia americana - Callitriche heterophylla Granite Outcrop Pool Group
Reference: NatureServe Biotics 2019
Description: These southern granitic outcrop pools of Georgia, South Carolina, Alabama, and Texas are characterized by <i>Isoetes</i> spp., with other plants which tolerate inundation and very dry summer conditions, such as <i>Pilularia americana</i> and <i>Callitriche heterophylla</i>. These small rock depressions fill with water after heavy rains and stay flooded for several weeks or more in the winter and early spring; in the summer they dry out and can be very hot. <i>Isoetes</i> spp. and <i>Crassula aquatica</i> are among aquatic plants which use a type of Crassulacean Acid Metabolism (CAM) which allows survival in inundation and in extreme drought. This is a very distinctive vegetation type which supports a number of rare plants and which is restricted to seasonally flooded pools on granitic outcrops of Georgia, South Carolina, Alabama, and Texas.
