Description and Ethnobotany
| Growth Form | It is a twining, parasitic plant with long, threadlike stems. The stems are yellow-green, brown, or orange, up to 8 m long, and adhere to trees or shrubs by small, round suckers. |
|---|---|
| Foliage | Its spirally arranged leaves are reduced to tiny scales. |
| Flowers | The bisexual flowers are borne on inflorescences and are sessile. The flowers are white, the outer 3 tepals are ovate while the inner 3 tepals are elliptical. |
| Fruit | Its one-seeded fruits are round berries, 6–9 mm wide, and enclosed in the enlarged, fleshy perianth (structure formed by the non-reproductive flower parts). |
| Others - Plant Morphology | The plant feeds off its host plant via a sucker-like attachment called a haustoria. |
| Habitat | It is common on seashores, scrambling over bushes, trees or thickets, up to 1,600 m altitude. It occurs locally along Mandai Road, Lentor Avenue, Narayanan Chetty Road, in Pulau Semakau, the Western Catchment Area, and Pulau Tekong. |
| Associated Fauna | Its flowers are insect-pollinated. Its fruits are dispersed by birds. |
| Cultivation | It is propagated by seeds. |
| Etymology | Greek Cassytha, after the genus Cuscuta, with which the plant much resembles; Latin fili, a thread; Latin form, shape, referring to the threadlike stems of the species |
| Ethnobotanical Uses | Medicinal: It is considered astringent and diuretic. The stems are also used as a tonic infusion in China, India and Vietnam for piles and diarrhoea. The stems are also used externally for cleaning ulcers and an infusion is used as eyewash. A mixture of the stem with sesamum oil can produce a hair-tonic. Others: The plant is made into a paste for making papers. The stem is used to produce a brown dye. An alkaloid, laurotetanin is present in the plant, and may cause death when taken in sufficient quantities. |
