It is pantropic in distribution. The plant has numerous short lateral arrested branchlets often rooting, aromatic, pinkish and glabrous, mostly found in the rocky riverbeds. The plant is distributed throughout peninsular and Western Ghats of India in the sandy and rocky beds of streams and rivers. Roots are cylindrical, often develops from lateral branches.

Leaves

The leaves are arranged alternately or clusters, overlapping, oblong to obovate or linear-oblong, usually 0.6-2.5 cm long and 0.2-0.9 cm wide, and short-stalked. They are entire or shallowly toothed, glabrescent or sparsed scabrous, ciliate along the margins, cuneate at base, obtuse or shortly apiculate at apex; petioles 0.5-3 mm long and greenish.

Flower

The flowers are small and crowded, and are borne in clusters at the end of branches. There are 5 narrow sepals which are about 4.5 mm long, with sharp points. The flowers are purplish or pink, 5-6 mm long, with 5 petals. Nearly 5 Stamens are exserted at the base of the corolla tube, with filaments up to 0.3 cm long and oblong-ovate anthers almost 0.2 cm in length.

Fruit

Fertile flowers are followed by somewhat rounded, subglobose, fleshy drupes that are about 4 mm in diameter, and contain four seeds. Fruits are initially green turning to yellowish to brownish-red with a strongly 4-lobed endocarp breaking up into 4 single-seeded pyrenes at an early stage. Seeds are oblong, without endosperm.
