Begonia aequilateralis

An extremely rare begonia of lowland forest in Selangor, Peninsular Malaysia, described by Irmscher in 1929 and considered probably the most endangered begonia in the Peninsula, known from a single small population in forest being cleared. Almost nothing is published about its microhabitat, so these targets follow the warm, shaded, very humid lowland forest of the Kepong-Sungai Buloh area. It is very unlikely to be in the hobby.

Where it grows wild

Known from lowland forest around Sungai Buloh and Sungai Kroh at Kepong, Selangor, on the edge of Kuala Lumpur, where the remaining habitat is threatened by clearing. The exact microhabitat (stream bank, rock or forest floor) is not recorded in the sources opened; most lowland Malaysian begonias grow on shaded, damp banks or rocks near streams.

Lowland; the Kepong and Sungai Buloh area lies below about 200 m. No specimen gives an elevation.
