description
Centella asiatica is a small, herbaceous, annual plant of the family
Mackinlayaceae (or as a sub-family of Apiaceae). 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
pericladial petioles, around 2 cm. The rootstock consists of rhizomes, growing
vertically down. They are cream 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.
common names & nomenclature
Centella may be derived from the verb “sip”, which is a reference to how the
plant continuously draws water from the marshy areas in which it lives.
