Species of the Genus Buddleja
Organisation of Buddleja
Buddleja species were divided into four sections by Leeuwenberg (1979):
SECTION: Buddleja – New World species distinguished by a valvate corolla e.g.: B. americana.
SECTION: Chilianthus – African species with anthers that protrude beyond the corolla e.g.: B. saligna.
SECTION: Neemda – the majority of species from all continents.
SECTION: Nicodemia – African species, many from Madagascar, distinguised by forming a berry (indehiscent) rather than a dry (dehiscent) seed capsule e.g.: B. madagascariensis.

Phylogeny of Buddleja
Approximate phylogeny of Buddleja within the order: Lamiales.
Buddleja and the related species in the Buddleja tribe are members of the Scrophulariaceae also known as the figwort family; the closest relatives within the family are Phygelius (cape fuchsia or cape figwort) and Verbascum (mulleins). Note that not all the Lamiale families are shown and that the tree is not to scale.
