Abstract:

Background and aims - Recent collecting in Equatorial Guinea, a country with incompletely documented biodiversity, resulted in an ample collection of the plant family Acanthaceae. Identifications resulted in the discovery of novelties, presented here.

Methods - Specimens from BRLU, BR, BM, P and K were investigated. Critical point-dried pollen was observed in the SEM.

Results - Three new taxa are described from Equatorial Guinea, two new species in the genera Crossandrella and Dischistocalyx and one new variety in Ascotheca. Distribution maps and illustrations for the two new species are provided. Pollen morphology adds evidence to distinguish between the three species of Crossandrella.
