Begonia atroglandulosa

Begonia atroglandulosa is a small Central African forest begonia described by Sosef in 1992. It is known from Gabon and the Republic of Congo, where it grows in lowland and hill rainforest at 50–950 m. It favours very wet, shaded rock faces beside waterfalls and steep slopes in mature forest, so it needs deep shade and near-saturated air.
