Abstract

Spiradiclis hainanensis H.S. Lo and S. purpureocaerulea H.S. Lo (Rubiaceae) are reported as new additions to the flora of Vietnam. In Vietnam, the genus Spiradiclis has been represented by only two species, S. leptobotrya (Drake) Pit. and S. caespitosa Blume. During our field investigations in the Lao Cai and Ninh Binh Provinces of northern Vietnam, we collected two interesting specimens of Spiradiclis that were earlier known only from China and unknown in Vietnam. Here, we report S. hainanensis and S. purpureocaerulea as previously unrecorded species from Vietnam. Detailed descriptions and color photographs are provided along with a taxonomic key for Spiradiclis species in Vietnam.
