Definition
Crateva adansonii is a species of flowering plant in the family Capparaceae, commonly known as the “three-leaved caper” or “bush caper.” It is a small deciduous tree or shrub native to tropical and subtropical regions of South and Southeast Asia.
Overview
The species occurs in a range of habitats, including dry deciduous forests, scrublands, and open grasslands, from sea level up to about 1,200 m elevation. It is distributed across India, Sri Lanka, Bangladesh, Myanmar, Thailand, Malaysia, Indonesia, and northern Australia. C. adansonii is valued in traditional medicine, where various parts of the plant are used to treat ailments such as fever, dysentery, and skin infections. The plant is also occasionally cultivated as an ornamental for its attractive yellow flowers.
Etymology / Origin
The generic name Crateva derives from the Latinized form of the Indian name “Kratib” used for some species in the group. The specific epithet adansonii honors the French botanist Michel Adanson (1727–1806), who contributed extensively to the taxonomy of Indian flora. The name was formally published by botanist William Roxburgh in the early 19th century.
Characteristics
- Growth form: Evergreen to semi‑deciduous shrub or small tree, typically 3–8 m tall, with a dense, spreading canopy.
- Leaves: Trifoliate, opposite or sometimes whorled; leaflets are oblong‑elliptic, 4–12 cm long, with an acute apex and smooth margins.
- Flowers: Bright yellow, bisexual, arranged in terminal racemes or panicles; each flower has four sepals, four petals, and numerous stamens, characteristic of the Capparaceae.
- Fruit: An elongated, dehiscent pod (capsule) 5–12 cm long, containing several seeds. The pod matures to a brownish color and splits open to release the seeds.
- Phenology: Flowering generally occurs during the pre‑monsoon period (April–June) in most of its range, with fruiting following the rainy season.
- Ecology: The flowers attract a variety of pollinators, including bees and butterflies. The seeds are dispersed mainly by gravity and, to a lesser extent, by birds that feed on the pods.
- Uses: In Ayurvedic and folk medicine, the bark, leaves, and roots are employed for anti‑inflammatory, antipyretic, and antimicrobial purposes. Some cultures use the tender shoots as a vegetable. The wood, though soft, is occasionally used for making small implements.
