%X A new species of Begonia sect. Petermannia (Begoniaceae), B. willemii Ardi, Girm. & D.C.Thomas, is described from Sulawesi, Indonesia. The species is a calciphile endemic to Sulawesi. It is morphologically similar to Begonia gemella but can be easily differentiated by its smaller leaves, a sparse, bristly indumentum on the adaxial lamina surface, simple monochasial male inflorescences, longer pedicels, fewer stamens and two-tepaled female flower. Its conservation status is provisionally assessed as Near Threatened (NT).
