Alsophila doctersii, synonym Cyathea doctersii,[1] is a species of tree fern endemic to Sumatra, where it grows in forest at an altitude of approximately 150 m. The trunk is erect and 2–3 m tall. Fronds are bi- or tripinnate and 2–3 m long. The stipe is covered with scattered flat, brown scales and some hairs. Sori occur near the fertile pinnule midvein and are covered by thin, brown indusia that are scale-like in appearance.[2]
A. doctersii appears to be most closely related to Alsophila javanica. Large and Braggins (2004) note that it may in fact be of hybrid origin between A. javanica and a member of the Alsophila latebrosa complex.[2]
The specific epithet doctersii commemorates botanist Willem Marius Docters van Leeuwen (1880-1960), who collected numerous plant species in Asia.[2]
