Begonia annulata

The ringed begonia is a rhizomatous species from the eastern Himalaya and hills of north-east India. It is a close relative of Begonia rex, with large, hairy, lopsided leaves marked by a silvery zone. Also known under the synonym B. griffithii, it holds the RHS Award of Garden Merit as a foliage plant for a warm, shaded, humid spot.

Where it grows wild

No habitat description was found in the sources checked. Its many field records in the southern Bhutan foothills, and its relatives in section Platycentrum, suggest it grows in moist, shaded evergreen forest on banks, rocks and stream sides.

Records in the southern Bhutan foothills, Nagaland, Arunachal Pradesh and the Sylhet hills suggest low to middle elevations, very roughly 300-2,000 m, but none of the records we saw gives an elevation.
