Begonia micranthera

Begonia micranthera, described by Grisebach in 1874, is an Andean begonia of Bolivia and northwest Argentina, generally treated as a tuberous species. Its records span 855–3450 m, mostly around 2300 m, in the Yungas and inter-Andean valleys, where a wet summer alternates with a long dry winter. Grow it in summer and rest the tuber dry and cool in winter.

Where it grows wild

Yungas montane forest edges, ravines and rocky banks, and moister spots in dry inter-Andean valleys. The tuberous habit comes from general knowledge of the species rather than a source we reached.

Recorded at 855–3450 m, median 2342 m (113 records).
