Abstract

A new Begonia species, Begonia abhak, from section Petermannia is described and illustrated. Growing on shady, moist, rocky slopes alongside a small creek of Bujon, Lanuza, Surigao del Sur. The new species resembles Begonia panayensis in having glabrous stems, membranous, shiny leaves, oblong to oblanceolate lamina, acuminate apex and green ovary with pink wings but is distinct in having short stems, broadly ovate stipules, acute leaf base, serrated margins, and the slashed or jagged to almost entire margins of the capsule wings. Based on IUCN criteria, B. abhak is hereby proposed as Least Concern (LC).
