Centella asiatica, a perennial herb also known as gotu kola, produces fanshaped, green leaves that are harvested and used for medicinal purposes.
The stems are slender, creeping stolons, green to reddishgreen in color, connecting plants to each other. It has long-stalked, green, reniform leaves with rounded apices which have smooth texture with palmately netted veins. The leaves are borne on pericladial petioles, around 2 cm.
The rootstock consists of rhizomes, growing vertically down. They are creamish in color and covered with root hairs.
The flowers are pinkish to red in color, born in small, rounded bunches (umbels) near the surface of the soil. Each flower is partly enclosed in two green bracts.
The hermaphrodite flowers are minute in size (less than 3 mm), with 5-6 corolla lobes per flower. Each flower bears five stamens and two styles. The fruit are densely reticulate, distinguishing it from species of Hydrocotyle which have smooth, ribbed or warty fruit.
