Leonardoxa africana (Leguminosae: Caesalpinioideae): a complex of mostly allopatric subspecies
Listed in GBIF
This dataset contains the digitized treatments in Plazi based on the original journal article Mckey, Doyle B. (2000): Leonardoxa africana (Leguminosae: Caesalpinioideae): a complex of mostly allopatric subspecies.
Description
Adansonia (3) 22 (1): 71-109, DOI: 10.5281/zenodo.4605796 ABSTRACT As currently circumscribed, the genus Leonardoxa is restricted to the type species L. africana (Baill.) Aubrév., occurring in coastal forests of Lower Guinea.
This work, based on field, greenhouse, and herbarium studies, demonstrates that L. africana is a complex of four closely related taxa, here treated as subspecies: L. africana subsp. africana, subsp. gracilicaulis McKey, subsp. letouzeyi McKey and subsp. rumpiensis McKey. The new taxa are described and relationships within the complex are discussed. The complex is interpreted as a ring species of mostly allopatric subspecies in which the two most extreme variants, the subspecies africana and gracilicaulis, have a narrow zone of sympatry in which they co-occur in the same communities and remain distinct.

Data on ecology and natural history are presented, emphasising ant-plant interactions. Coevolutionary interactions with certain ants appear to be an important factor driving differentiation in this complex. Of the four subspecies, all but gracilicaulis are myrmecophytes, with swollen hollow stems occupied by symbiotic ants.
Several traits show marked variation among different taxa of the complex. These include not only traits directly related to antplant interactions, but also others which are unrelated or only indirectly related to ants. Keys and range maps are presented for the four subspecies.
