Euphorbia fanjingshanensis (Euphorbiaceae), a new species from section Helioscopia in southwestern and central China
Euphorbia fanjingshanensis , a new species from southwestern and central China, is described and illustrated. Morphologically, it is most similar to E. micractina and E. hylonoma in E. subg. Esula sect. Helioscopia , but can be readily distinguished by its lanceolate leaves with acute apices, reddish to crimson peduncles, and tuberculate capsules, and ovoid-globose dark brown seeds (ca. 2.5 × 2 mm). Phylogenetic analyses based on combined nuclear ITS and plastid ndhF sequences further confirm its placement within the clade of E. sect. Helioscopia , and reveal a close relationship with other species of the East Asian Clade.
