Abstract
A new species of Spiradiclis (Rubiaceae) was found during our field trip to Guangxi, China, and is described here as Spiradiclislonganensis R. J. Wang. This species is readily distinguishable from other prostrate and decumbent species of the genus described previously by dense pubescence all over the plant, 5-20 small flowers per cymose, linear calyx lobes, and tubular corolla. The conservation status of VU was preliminarily assessed according to IUCN categories and criteria.
