Abstract

Spiradicliskarstana, a new species of Spiradiclis (Rubiaceae) collected from Yunnan, China, is described for the first time. It is morphologically close to S.jingxiensis, but differs from the latter mainly by its inflorescences with 5-9 flowers, its 1.5-2.4 mm long peduncles, its stipules shorter than 1 mm and the 5-12 pairs of secondary veins. The conservation status is assessed as "Vulnerable" (VU) according to the IUCN Red List Categories and Criteria.
