Psorospermum belongs to the tribe Vismieae (Hypericaceae). Morphologically, Psorospermum is very similar to Harungana, which also belongs to Vismieae along with another genus, Vismia. Interestingly, Harungana occurs in both Madagascar and mainland Africa, as does Psorospermum; Vismia occurs in both Africa and the New World. However, the phylogeny of the tribe and the relationship between the three genera are uncertain. Using freshly collected specimens from my fieldwork as well as extant herbarium specimens, I aimed first, to generate a phylogeny of Psorospermum; second, to investigate its biogeography; and third, to investigate species boundaries within Malagasy Psorospermum …
