Abstract
A new species of Ardisia (Primulaceae), A. rubricaulis S. Z. Mao & C. M. Hu from Guangxi, China is described and illustrated. The new species belongs to Ardisia subgen. Crispardisia which is characterised by leaves with marginal glands (vascularized nodules). Its affinity is with A. maculosa Mez, but can be easily distinguished from the latter by its lateral and glandular puberulent inflorescence and by the underside of leaves and corolla-lobes being densely black-punctate.
