MendonciaAgneta Julia Borg
Mendoncia is one of five genera in Thunbergioideae, comprising ca. 60 species distributed mainly in Central and South America with some African representatives and a few species native to Madagascar.
Discussion of Phylogenetic Relationships
To date, there is no comprehensive subgeneric taxonomic treatment of Mendoncia. Some species have earlier been ascribed to two separate genera; Monachochlamys and Afromendoncia. Due to the lack of sufficient divergent characters, both genera were sunk back into Mendoncia by Benoist (1944), and recent DNA analyses show that neither Monachochlamys nor Afromendoncia are monophyletic (Borg et al. 2008). Relationships within Mendoncia correspond well to the geographic distribution of the genus. The genus displays a trans-Atlantic disjunction, with one clade consisting of species endemic to Madagascar, which is sister to a large group consisting of one African mainland clade and an entirely American clade.
