Abstract

The species Tarenna pendula (Rubiaceae), a small shrub, is newly described and illustrated from southwestern Guangxi Autonomous Region, China. This species is similar to Tarenna tsangii but is readily distinguished by its asymmetrical leaves, larger vegetative leaves than inflorescence leaves, adaxially pilosulous blades, pendulous inflorescences, longer pedicels (15–35 mm vs. 4–7 mm in T. tsangii), shorter corolla tubes (1–1.4 cm vs. 1.8–1.9 cm), multiple ovules per locule (vs. two), and sparsely pubescent fruits containing 13–19 seeds (vs. glabrous fruit containing only four seeds).
