The flora of the south-western tip of southern Africa, the Cape flora, with some 9000 species
in an area of 90000 km2 is much more speciose than can be expected from its area or …

Angiosperms and their flowers have greatly diversified into an overwhelming array of forms
in the past 135 million years. Diversification was shaped by changes in climate and the …

Chloroplast DNA sequences are a primary source of data for plant molecular systematic

Floral morphology is key for understanding floral evolution and plant identification. Floral
diagrams are two-dimensional representations of flowers that replace extensive descriptions …

The construction of classifications, as well as the understanding of biological diversity,
depends upon a careful comparison of attributes of the organisms studied (Stuessy, 1990). It …

We examine the eudicot order Myrtales, a clade with strong Gondwanan representation for
most of its families. Although previous phylogenetic studies greatly improved our …

This chapter brings together aspects of floral development and evolution in angiosperms
derived from the diversity of structures of extant plants. It provides a framework especially …

Senna (Leguminosae) is a large, widespread genus that includes species with
