Botany
Limang-sugat is an erect, branched, rather slender undershrub or half-woody plant usually about 1 meter in height. Leaves are thin, elliptic-ovate to oblong-ovate or oblong-lanceolate, 5 to 12 cm long, the upper ones often reduced, pointed at the tip and narrowed to the petiole at the base. Peduncles are axillary and longer than the petioles, bearing near their apices 1 to 3 or more racemose or cymose flowers. Calyx is green, 5 to 7 mm long, with elongated, linear teeth. Corolla is white, the middle lobe of the lower lip has a purple spot at the base; the tube is slender and 2.5 to 3 cm long; lobes are spreading, elliptic to elliptic-oblong, and about 1.2 cm long. Fruit is a hairy, stalked capsule, about 2 cm long.
