Description

The trunk of this species can grow to a height of 5 m or more. The stipes are persistent, spiny and purplish towards the base, and covered in brown shiny scales. Fronds are 1–3 m long and three-limbed. The sori, producing the spores, are large and round. Like many tree ferns, it features a "skirt" of dead leaves that do not drop off the crown and form a barrier for parasitic climbing plants.[2]

Distribution and habitat

A. spinulosa occurs in humus soils in shadowed forest locations, and is widely distributed across Asia including China, Nepal, India, Burma, Myanmar, and Japan.[3][2]

Use by humans

The stems are rich in starch and edible. Stem chips also see use as fern chips as a substrate for the cultivation of orchids.[2]
