Introduction |
Casuarina glauca Sieber ex Sprengel
- Family: Casuarinaceae
Vernacular names
- Swamp she-oak, swamp oak (En)
- Malaysia: ru paya (Peninsular).
Distribution
Native to Australia in a narrow belt along the east coast, introduced into other areas for dry-land afforestation (e.g. Israel), planted in Singapore.
Uses
Suitable for thick hedges on swampy or sandy soils, as pruning will encourage root suckers. Used for firewood in its native habitat and considered worth testing as a firewood crop elsewhere.
Observations

- Leaves reduced to 12-17(-20) "teeth".
- Male spike 1.2-4 cm long; female cone 9-18 mm × 7-9 mm.
- Fruit a compound cone-like structure, 1-2 cm × 1-1.5 cm.
