摘要：
Two new species of Annonaceae from the threatened lowland coastal forests of Tanzania are described and illustrated. Xylopia mwasumbii D. M. Johnson has distinctive flattened monocarps, unique among its African congeners. Uvaria puguensis D. M. Johnson is a small-flowered species belonging to a complex including, in East Africa, U. angolensis, U. lucida, and U. tanzaniae. A key to the taxa of the U. angolensis group in East Africa is provided.
