The B. monnieri plant has no smell. The erect portion of the stem is 10 - 30 cm tall and is glabrous. The leaves are obovate in shape, 6 - 17 mm long, 3 - 8 mm wide, and only have a single vein (rarely 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 flower is white in color and sometimes tinged with blue and 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.[2]




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.[3]


B. monnieri has been observed to flower in June and July and fruit in June.[3][4] Other sources say the plant flowers from April to frost.[2]


Bacopa monnieri has been observed at the Archbold Biological Station with sweat bees from the Halictidae family such as Lasioglossum pectoralis, and L. puteulanum and leafcutting bees from the Megachilidae family such as Megachile brevis pseudobrevis, and M. georgica.[5]:
