Cycas inermis

A trunk-forming cycad of seasonal tropical forest in central and southern Vietnam, reaching 1.5–4 m with fronds 2–3 m long. It wants year-round warmth, strong but broken light and a marked drier spell in the northern winter.

Where it grows wild

Climate sites at about 85 m and 800 m; the coastal Vietnamese range is mostly lowland to low hills.
