Cyathea alleniae is a species of tree fern native to the Malay Peninsula where it grows in forest margin on steep ground at an altitude of approximately 1200 m. The trunk is erect about 4 m tall and 15 cm in diameter. It is usually unbranched but may branch to form several small crowns. Fronds are bi- or tripinnate and 1-2 m long. The stipe is spiny at the base and at least partially covered by scales.
