H. Xia,J. B. Ni,Y. H. Tong & Z. Y. Niu,a new species from Danxia Mountain,Guangdong,China,is described and illustrated. The new species is morphologically similar to D. latiflorus,D. minor and D. pulverulentus,but differs in having a ring of brown sericeous hairs at the infranodal to intranodal regions,culm leaf sheaths with dense appressed brown setae at the middle and lower parts of the abaxial surface and several yellowish white vertical stripes near the margins,ca 2 mm tall culm sheath ligules with a concave and serrulate margin,and 7-16 foliage leaves per ultimate branch with broadly triangular auricles and 1-5 mm long oral setae.
