| Distribution | Throughout the Coastal Plain, barely reaching the eastern Piedmont.
This is a mainly Coastal Plain species, with a split range. It occurs along the Coastal Plains from MA south to southern FL and west to central TX. It also ranges west of the Appalachians and Cumberlands from northwestern PA and IL south to TX.

| Abundance | Infrequent to at least locally fairly common in the Coastal Plain, but as it is tiny, it is either overlooked or most botanists simply do not bother to collect it and other duckweeds and watermeals. The website editors feel that a State Rank of S4 is appropriate. | |
| Habitat | As with watermeals and duckweeds, it occurs only on still or very slow moving water of pools, ponds, lakes, and swamps. | |
| Phenology | Flowers and fruits from April to June; however, flowering is rarely seen. | |
| Identification | This is a tiny floating species, with the fronds being quite narrow and falcate shaped, about 1/3-inch long but only about 1/20-inch wide. The plants lack roots, as do the Wolffia species. The plants often are attached together into a tangled, "stringy" mass. All other similar floating species -- genera Lemna, Spirodela, and Wolffia, have rounded to elliptical fronds. | |
| Taxonomic Comments | The species was named as Wolffiella floridana in older references.
