Description

Rotheca serrata is a small bush growing to a height of up to 8 feet (2.4 m). The squarish stems are only sparsely branched. The young growth is glabrous and the leaves are in opposite pairs or develop with three at a node. They are oval, serrated and hairless with an acute base and a stout petiole.[2] The flowers are showy and develop in cymes which are covered with short, soft erect hairs. The individual flowers are small and form part of an erect pyramidal panicle up to 10 in (25 cm) long. The corolla of each flower is blue, cylindrical, hairless outside and hairy inside and the stamens arch out from it.[3] The four upper lobes are flat and spreading while the lowest lobe forms a concave lip. The fruit is a four-lobed fleshy drupe, green at first and black when ripe.[4][5]

Distribution

Rotheca serrata is native to eastern India, Sri Lanka and Malaysia and is found in forests.[4]

Uses

The plant is also used in Ayurveda for snake bites.[4]
