THE FLOWERS
The stems are slender, creeping stolons, green to reddish-green 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 pericardial 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 FRUITS
The fruits are densely reticulate, distinguishing it from species of Hydrocotyle that have smooth, ribbed or warty fruit. The crop matures in three months, and the whole plant, including the roots, is harvested manually.

Note: The content in saponins is variable according to the region and the year. But generally speaking, the richest Centella in saponins is found in Madagascar and can reach 8%. In China, the content is between 1.5 to 3%. In India, the content is usually lower, not more than 1%.
Moreover, some saponins are characteristics to some place like terminoloside specifically found in Madagascar.
