Vaccinium dehongense (Ericaceae), a new species from Yingjiang County of Yunnan Province, China is described and illustrated. This new species belongs to Vaccinium sect. Epigynium and is most similar to V. vacciniaceum, but differs from the latter in the subsessile leaves, the inflorescence usually developing at leafless nodes, the shorter pedicels and the filaments being ca. 1/3 length of the stamens. Since the type locality of this new species is very near the border between China and Myanmar, it is probably also distributed in the adjacent area of Myanmar. As no population assessment of this species in its whole distribution area is made, it is best to assign a conservation status of 'Data Deficient' (DD) for this species. [ABSTRACT FROM AUTHOR]

Vaccinium usneoides (Ericaceae), a new species from Fugong County of Yunnan Province, China is described and illustrated. This new species belongs to Vaccinium sect. Calcicolus and is most similar to V. brachyandrum, but differs in its branches hanging down, much smaller leaf blades, shorter inflorescences and pedicels, non-glandular tomentellate or densely pubescent inflorescence rachis and pedicels, densely white-pubescent hypanthium and pilose filaments.

A new species, Fordiophyton tereticaule, from China, is described and illustrated here based on morphological and molecular evidence. It is morphologically similar to F. faberi in having erect stems, slightly oblique and membranous leaf blades, broadly ovate to suborbicular bracts, and oblong petals, but differs by the terete stems, densely puberulous petioles, and elliptic leaf blades. Our phylogenetic analyses based on plastid genome and nrITS data indicate that this new species is clustered with four Fordiophyton species of Yunnan but placed far apart from F. faberi. An updated key to the genus is also provided. [ABSTRACT FROM AUTHOR]

Agapetes heana Y. H. Tong & J. D. Ya (Ericaceae), a new species from Lüchun Xian, Yunnan Province, China is described and illustrated. This new species is assigned to Agapetes sect. Agapetes ser. Longifiles Airy Shaw. It is closest to A. inopinata Airy Shaw and A. oblonga Craib, but differs in having bead-like tubers, leaf blade with a wholly serrulate margin, subulate and much longer calyx lobes, much larger corollas that are carmine, green at the apex and maroon on angles, and longer stamens without spurs on the back.
