Abstract

Lacandonia schismatica comprises a new family, genus, and species. Its most conspicuous character is the central position of the androecium, surrounded by the apocarpous gynoecium. This arrangement has not been recorded before for angiosperms. The androecium consists of three (sometimes four) bilocular anthers with introrse dehiscence. The gynoecium is apocarpic. Each carpel contains a single ovule that is sessile, basal, anatropous and bitegmic; the inner integument forms the micropyle. The position of the style on the ovary changes during development. The endosperm is of the nuclear type. The embryo of the mature seed is poorly developed. The fruit is indehiscent.
