Sida hernandioides L’Héritier, Stirp. Nov., 121, plate 58. 1789; S. polyantha Schlechtendal ex Link; Wissadula mucronulata A. Gray ex Torrey

Flowering fall–early winter. Deciduous forests, disturbed vegetation; 10–100 m; Fla., La., Tex.; Mexico; West Indies; Central America; South America; Africa.

Wissadula hernandioides is very uncommon within the flora area, having been reported [as W. amplissima (Linnaeus) R. E. Fries, following Fries (1908)] from only Cameron County, Texas; Collier County, Florida; and Louisiana (unvouchered).

It has been widely but incorrectly referred to Wissadula amplissima. A. Krapovickas (1996) clarified the correct application of the latter name to a different Neotropical species.
