Vegetative characteristics

Bacopa species grow as herbaceous plants . The stems are erect or creeping. The opposite leaves have a simple leaf blade.

Generative characteristics

The flowers are individually in the leaf axils or in lateral or terminal racemose inflorescences . There can be one or two cover sheets.

The hermaphrodite flowers are zygomorphic and have a double flower envelope . The rarely four, usually five completely free sepals overlap like roof tiles, with the top one being the largest. The five petals are fused Roehrig. The corolla tube is more or less clearly two-lipped depending on the species. The lower lip is three-lobed and the upper lip is two-lobed. There are usually four, very rarely five stamens . The scar is widened, head-like or bilobed.

The egg-shaped or spherical, quadruple capsule fruits are double-grooved and contain many tiny seeds.
