Pleurolobus gangeticus (L.) J.St.-Hil. ex H.Ohashi & K.Ohashi

Daun bulu ayam (Pleurolobus gangeticus) is a shrub up to 2 meters tall from the Fabaceae family spread from tropical Africa to Australia. Its root is an important part of the Dasmoola kvatha remedy in Indian Ayurveda, serving as a bitter antipyretic tonic believed to be beneficial for typhoid fever. Its fibrous stem is also used to make paper and, in the Philippines, traditional shrimp traps.

Daun bulu ayam can grow in various habitats, generally often found in open forests, disturbed areas in rainforests, seasonal forests, thickets, sand dunes, and in dry sandy soil near water. In Indo-China, this plant can be found in savannas and bare areas, fences and along forest trails, up to an elevation of 1,900 m asl.
