Sesbania herbacea

The best way to differentiate between Sesbania herbacea, Sesbania drummondii, and Glottidium vesicarium is the morphology of the fruit. Sesbania herbacea has round, very long and narrow fruit, Glottidium vesicarium has short, flattened, fruit, and S. drummondii (and S. punicea) has short, square fruit. Flowers yellow mottled with purple. Seedling identification: Cotyledons (seed leaves) lance- to spoon-shaped. First true leaf is simple. Older leaves numerous, oblong, with oblong leaflets.

Infrequent, sometimes locally abundant, in Louisiana and the eastern third of Texas. A weed in disturbed areas and agricultural fields.

Ditches, fields and waste places, alluvial soil.
