HABIT: Spreading to decumbent herbaceous perennial,
2-6 dm.; flowering July-September.
SPECIES: May be confused with Diodia
virginiana but has many more and smaller flowers in the axils.
RANGE: S. OH to S. MO, s. to FL and TX.
RANGE: There are post-1950 collections
from 6 counties in the Ohio River Valley: Adams, Clermont, Hamilton, Lawrence,
Scioto, and Washington. There is a
pre-1950 specimen from Fairfield County.
STATUS: 1980 to present: Potentially
HABITAT: Swamps, wet woods and openings; in Ohio
found mostly on muddy shores and low banks of the Ohio River.
HAZARDS: Sudden changes in water level, overshading
by woody species in later successional stages.
POTENTIAL: Unknown; probably good due
to perennial habit.
GUIDELINES: Collect mature flowering
COMMENTS: Populations of this species fluctuate
greatly from year to year, presumably in relation to changes in water level in
the Ohio River.
