Aglaonema rotundum

A small, creeping Sumatran Aglaonema with broad, almost round leaves 6–13 cm long. The upper side is glossy dark green with pink or whitish veins and the underside is dark red. It is a parent of many red-leaved hybrids. Its wild ecology is barely documented: Nicolson knew only one certainly wild collection, from near a waterfall at 360 m near Medan. With so little known, a steady, humid, shaded enclosure is the safest approach.

Where it grows wild

The one wild collection Nicolson cited came from near a waterfall at 360 m in North Sumatra. GBIF specimens add lowland forest in the Langkat, Bohorok and Sikundur areas of the Leuser region and the Bilah area. The stem is decumbent, with only the last 5–6 cm upright, and it produces papery cataphylls among the leaves. The wild plant is much smaller than cultivated material.

Only one elevation is published: 360 m near a waterfall. The other specimen localities are lowland forest in North Sumatra, probably below about 500 m.
