Potentilla, Duchesnea, and Fragaria in Malesia (Rosaceae)

Nine species of Potentilla are recognized for the Malesian area, two more are insufficiently known. Of the nine species, one is new (P. hooglandii), a new variety is also described ( P. foersteriana var. ima). Duchesnea is considered congeneric with Potentilla. Although for Fragaria the same case could be made, it is kept separated for practical reasons and for reasons of nomenclatural stability. In Malesia two species occur, both introduced. Some reductions and nomenclatural rectifications will also be found in the present revision which is a precursor towards a revision of the Rosaceae for Flora Malesiana.
