Observation Narrative	Plot consists largely of annual plants inhabiting a late-season draw-down of a muck-bottomed Coastal Plain seasonal pond. On slightly higher elevations adjacent to the plot, the plants Rhynchospora macrostachya, Fimbristylis autumnalis, Torreyochloa pallida, Polygonum hydropiperoides, and Cephalanthus occidentalis occur. During "wetter" years this habitat probably remains inundated year-round.
