ABSTRACT

Primulina cangwuensis X. Hong & F. Wen (Gesneriaceae), a new species growing in rocky crevices on a limestone hill in Guangxi, China, is described and illustrated. It is morphologically similar to P. repanda, P. subulata, P. jianghuaensis and P. lobulata, but can be distinguished from its congeners by the different shape of leaves, bracts and calyx, as well as by the different indumentum of pedicels and stamens.
