Rhexia mariana L.
Coefficient of Conservatism: 10
Coefficient of Wetness: -5
Wetness Index: OBL
Physiognomy: Nt P-Forb
Status: T

Moist sandy upper shores of ponds and swales, sandy open depressions in oak savanna.

Much rarer and more local than R. virginica, R. mariana tends to grow in somewhat drier habitats and begins flowering a little later. The leaves are also narrower, the distal often lanceolate or even linear, and the spreading pubescence of the stem is uniformly distributed even into the inflorescence. In R. virginica, the distal leaves are typically ovate, and the spreading pubescence is sparse or absent in the inflorescence.
