Abstract
Leptomischus bracteosus, a new species of Rubiaceae from Yunnan, China, is described and illustrated. It shares similarities with L. primuloides and L. parviflorus, including similar shape, indumentum, the number of secondary veins on isophyllous leaves, and the inflorescences bear several distylous flowers. However, it differs from them and other congeners due to it having four bracts and bracteoles, resembling stipules that are subtriangular to rhombic or broadly ovate with truncate base, and the calyx limb lobed for approximately one-third. An updated key to the world species of Leptomischus is also provided.
