Specifically for ''B. monnieri'', the plant has no smell. The erect portion of the stem is 1-3 dm tall and is glabrous. The leaves are obovate in shape, 6-17 mm long, 3-8 mm wide, and only having a single vein. It is rare to see 2-3 veins. The internodes are longer than the leaves. The pedicel is longer than the subtending leaf. The bractlets are present. The largest sepals grow up to 5-7 mm long, and 3-4 mm wide. The corolla is white in color and sometimes tinged with blue. The corolla is rotate to regular, growing up to 8-10 mm long. The lobes grow to the same size as the tube. There are 4 stamens which are subequal. Flowers from April to frost (Radford 1964). | Specifically for ''B. monnieri'', the plant has no smell. The erect portion of the stem is 1-3 dm tall and is glabrous.

Description
Baccharis genus are dioecious, glabrous shrubs. They are rarely small trees. The leaves are alternate, fleshy, toothed or entire. The heads pedunculated or sessile, most of the time in 3-5 glomerules. The involucres are cylindric, 4-5 mm long, 2.5-3.5 mm broad. The bracts are imbricate, sometimes purplish in color, and obtuse. The flowers are discoid and yellowish in color. The nutlets are tan in color, lustrous, cylindric, 10-ribbed, glabrous, and 1.2-1.5 mm long. The pappus bristles are white to tan in color. The capillary is 7-10 mm long. (Radford 1964).
Specifically for B. monnieri, the plant has no smell. The erect portion of the stem is 1-3 dm tall and is glabrous. The leaves are obovate in shape, 6-17 mm long, 3-8 mm wide, and only having a single vein. It is rare to see 2-3 veins. The internodes are longer than the leaves. The pedicel is longer than the subtending leaf. The bractlets are present. The largest sepals grow up to 5-7 mm long, and 3-4 mm wide. The corolla is white in color and sometimes tinged with blue. The corolla is rotate to regular, growing up to 8-10 mm long. The lobes grow to the same size as the tube. There are 4 stamens which are subequal. Flowers from April to frost (Radford 1964).
Ecology
Habitat
In the Coastal Plain in Florida, B. monnieri has been found in shallow water of a shaded ditch; with Eleocharis flavescens in muck of small floating island in a ditch; sand fill near a salt marsh; and shallow brackish water (FSU Herbarium).
Phenology
It has been observed to flower and fruit in June (FSU Herbarium).
Pollination
The following Hymenoptera families and species were observed visiting flowers of Bacopa monnieri at Archbold Biological Station (Deyrup 2015):
Halictidae: Lasioglossum pectoralis, L. puteulanum
Megachilidae: Megachile brevis pseudobrevis, M. georgica
