Atalantia racemosa is a thorny shrub or small tree belonging to the citrus family, Rutaceae. It is native to the Indian subcontinent and parts of Southeast Asia, including India, Sri Lanka, Myanmar, Vietnam and the Philippines. It is valued as a native wild relative of cultivated citrus plants and is recognised by its distinctive clusters of flowers.
The plant generally grows as a compact shrub or small tree, sometimes reaching around 8–12 metres in height. Its branches may bear straight axillary spines. The leaves are simple, alternate, leathery and elliptic to ovate-oblong, with entire or slightly crenulate margins and a characteristically blunt or shallowly notched tip.
The flowers are small, creamy white and fragrant, arranged in elongated racemes arising from the leaf axils. The fruit is a small, rounded berry that turns orange when ripe and contains a few seeds.
Habitat
Atalantia racemosa occurs in tropical forests, including evergreen, semi-evergreen and dry deciduous forest habitats. It is found in parts of peninsular India and the Western Ghats, often in scrubby forest margins and other seasonally dry or open woodland habitats.
Planting and Care
- Light: Prefers full sunlight to partial shade.
- Soil: Grows in well-drained soil and can adapt to different soil types.
- Watering: Water regularly while young; established plants can tolerate some seasonal dryness.
- Climate: Suited to warm tropical and subtropical climates.
- Maintenance: Requires little maintenance once established. Handle carefully because some branches bear sharp spines.
- Propagation: Can be propagated through seeds.
Additional Information
- Citrus Relative: As a member of Rutaceae, it is related to cultivated citrus plants such as lemons and oranges.
- Traditional Uses: The species is recorded in Indian medicinal-plant references for traditional applications. Such records describe historical practices and do not establish clinical effectiveness.
- Ecological Value: As a native woody species, it contributes to the diversity of tropical forest and scrub habitats.
- Flowering and Fruiting: Regional botanical records report flowering and fruiting mainly from October to May, although the season can vary with location.
- Identification: Its thorny branches, simple leathery leaves and elongated clusters of creamy-white flowers help distinguish it from other species of Atalantia.
