Description and Ethnobotany
| Growth Form | Erect shrub, able to grow up to 3 - 4 m tall. |
|---|---|
| Foliage | Pinnately compound leaves are composed of 6 - 12 pairs of leaflets (30 - 60 cm long). Oblong leaflets are smooth and thinly leathery (6 - 15 cm long, 3.5 - 7.5 cm wide). They have a rounded tip with a slight indentation in the middle. |
| Flowers | Flowers are arranged in a vertical column and bloom from the base of the column. The inflorescence, known as a raceme, resembles a lit, yellow candle, because the flowers at the base are yellow, while the unopened flower buds at the top are covered by orange bracts. |
| Fruit | Winged pods are dark purple to black, smooth and 4-sided. They contain 50 - 60 flattened, triangular to squarish seeds. |
| Habitat | Often occurs on wet soil in wastelands and flood plains. |
| Associated Fauna | Ants protect the plant from caterpillars and are rewarded by nectar produced by extrafloral nectaries. |
| Cultivation | This easy-to-grow, fast-growing species is highly adaptable, tolerating both drought and waterlogged soils. Individual should be spaced 2 - 5 m apart. It tends to attract ants. Propagate by seed, division, or semi-hardwood cuttings. Plants started from seed will flower in about 6 months. To prevent it from becoming invasive, removed the seed pods before they split open. |
| Etymology | Genus Senna is derived from the Arabic name "sana", which refers to the laxative leaves and pods. Species alata means wing-like fruits. |
| Ethnobotanical Uses | Medicinal: The leaves and plant sap have anti-fungal properties, because they contain chrysophanic acid. In the Philippines, it is added to shampoo and soap for its anti-fungal properties. It also contains saponin which acts like a laxative and can be used to remove intestinal parasites. |
