Begonia natunaensis

A Begonia described in 2014 from Mount Ranai on Natuna Besar, an island in the South China Sea off Borneo. The type specimens were grown from plants brought from the wild, and little else is published. Treat it as a warm, very humid, ever-wet tropical forest begonia.

Where it grows wild

No habitat notes are published. The type label records Mt. Ranai at about 100 m. Mt Ranai is a granite mountain covered in humid evergreen forest, where most begonias grow on shaded, damp banks and rocks.

The type label gives about 100 m. The measured site is at about 1,100 m, which is higher than Mt Ranai's summit (under 1,000 m), so the measured temperatures are too cool.
