Abstract

Danxiaorchis mangdangshanensis, a new mycoheterotrophic species from Fujian Province, China, is described and illustrated. The new species is morphologically similar to D. singchiana, but its callus of labellum is a less distinctive Y-shape with three auricles on the apex, four pollinia that are narrowly elliptic in shape and equal in size, and it lacks fine roots. The plastome of D. mangdangshanensis is highly degraded. Phylogenetic analyses distinguished D. mangdangshanensis from its congeners, D. singchiana and D. yangii, with strong support based on nrITS + matK and plastomes, respectively.
