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.[2]
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.[2]
Distribution
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.[3]
Phenology
B. monnieri has been observed to flower in June and July and fruit in June.[3][4]
Pollination
The following Hymenoptera families and species were observed visiting flowers of Bacopa monnieri at Archbold Biological Station[5]:
