Pilularia americana (American Pillwort)
Granitic outcrop in a shallow pool, York County, South Carolina. This plant is TINY - the stems are about 1" tall.
From Weakley (2015): "This peculiar plant has a puzzling distribution, being known from several disjunct regions: WA to s. CA; NE and MO south to c. TX; SC, GA, TN, AL, and Mexico (Durango and Baja California Norte); similar plants, perhaps conspecific, occur in South America and Africa. The apparently fragmented distribution may be partly explainable by the inconspicuous nature of the plant. First reported for SC in 1993 (J. Allison, pers. comm.)."
