摘要：

A new species of Begonia in sect. Diploclinium, B. blancii M. Hughes & C.-I Peng, is described from the Bulalakaw Falls area in Palawan. A somatic chromosome number of 2n = 30 was determined. Begonia blancii is allied to B. suborbiculata and other 2-locular species in Begonia sect. Diploclinium, but is very distinct in having triangular-spathulate leaves. It shares clustered stomata with a number of other Begonia species, which are likely to help it reduce water loss through transpiration during the dry season. Its IUCN status is considered to be Least Concern.
