Zehneria grandibracteata (Cucurbitaceae), an overlooked new species from western Kenyan forests

Zehneria grandibracteata, a new species of Cucurbitaceae from western Kenya, is described here, based on morphological and molecular data. It has long been misidentified as the widely-distributed species Z. scabra. However, it differs by its ovate leafy probract at the base of the inflorescences, subglabrous condition of the entire plant, shorter receptacle-tube and filaments, as well as denser and sessile inflorescences. Furthermore, the molecular phylogenetic analysis of Zehneria, based on nrITS sequences, further supports the argument that Z. grandibracteata should be segregated from Z. scabra.
