Description and Ethnobotany

Growth Form It is a evergreen shrub or tree up to 15 m tall, covered with hair, with slender leaves hanging freely at the end of the branches. A strong smell of resin, lime and ivy is also emitted when the plant is crushed.
Foliage Its leaves are 20–61 cm long, with 7–20 pairs of leaflets. Its alternate, short-stalked leaves have thinly leathery leaf blades that are oblong-egg-shaped to lance-shaped or slightly crescent-shaped, 2–20 by 1–7 cm, and with asymmetrical bases. They also have slightly wavy or faintly notched margins.
Flowers Its green flowering shoots are 10–45 cm long, and found from the end of leafy twigs, or at the leaf axils. They bear flowers that are about 7.6–10 mm wide, and yellowish or greenish.
Fruits Its smooth fruits are broadly ellipsoid, 0.8–2 cm long, ripen green then white or pinkish, and found in hanging shoots. They emit a smell of sour, resinous oranges when crushed. Each fruit also contains 1–2 green seeds.
Associated Fauna Its flowers are insect-pollinated. It is also the preferred local food plant for caterpillars of the butterflies, the emerald swallowtail (Papilio palinurus), and the lime butterfly (Papilio demoleus malayanus). The adult of the latter lays its eggs singly on the young leaves of the host plant. Its fruits are probably eaten by birds.
Cultivation It can be propagated by seed.
Etymology Latin Clausena, commemorating Clausen, a botanist known to Burmann; Latin excavatus, to make hollow, referring to the bases of the filaments (stalks of stamens)
