Global description
Bacopa crenata is firstly prostrate then erect, rooting at lower nodes, measuring 10 cm to 1 m long, glabrous. The stem is spongy, the leaves are sessile and opposite, narrowly lanceolate, crenelate- serrated at the top, with a single midrib. White flowers, in tube, are usually solitary in the axils of the leaves. The fruit is a capsule containing numerous seeds.
General habit
Annual, glabrous plant, creeping then erect, rooted at the lower nodes. It measures between 10 cm and 1 m long.
Underground system
The taproot with few roots at the lower nodes.
Stem
The stem is spongy, with squarish section. It is glabrous and shiny.
Leaf
The leaves are simple, opposite and decussate. They are sessile, with elliptic lanceolate blade, base attenuate in acute corner, wedged apex, crenelate-serrated in the upper half. They measure 2 to 3.5 cm long and 5 to 11 mm wide. Venation is reduced to a central rib which is prominent on the upper face. Both sides are glabrous.
Inflorescence
The flowers usually solitary, are located in the leaf axils.
Flower
Pedicel and calyx are glabrous, unlike Bacopa floribunda whose pedicel and calyx are pubescent. The calyx consists of 5 free sepals of different form and appearance. They measure 7-8 mm long and 5-6 mm wide, with shortly ciliated margin. The dorsal sepal is enlarged oval, with cordate base, rounded obtuse apex, and is traversed by a network of ribs. The lateral sepals are narrow oval lanceolate, with rounded base, and narrowly acute apex. The ventral sepal is oval, rounded base and top. White flower with purple throat and veins, constitute of a tube terminated by two lips: the upper slightly bilobed, the lower, wider and deeply divided into three lobes. 4 stamens are inserted on the corolla tube. The superior ovary is extended by an elongated style ending in a bifid stigma.

Madagascar: Bacopa crenata grows on waterlogged, more or less flooded soils, quite fertile in sunny or lightly shaded places. It is a weed in lowland rice fields in semi-intensive culture system, in marshes and canals, humid or slightly flooded areas of low altitude on the East Coast and East of the island.
Reunion: absent.
