Abstract

Peliosanthes curviandra is described and illustrated as a new species from southern Vietnam. The new species is characterized by the unusual androecium comprising three erect and curved stamens, perfectly inferior ovary, and a slender tortuous style. The results of observations on the androecium structure and micromorphology of leaf blades were also presented, and the data obtained were briefly discussed in comparison with those known for some other congeners.
