Sedum danxiacola S.Y.Meng & B.Chen, a new species of Sedum, is found on the Danxia landform near Wuyi Mountain, China. Sedum danxiacola belongs to sect. Filipes and is similar to S. drymarioides Hance and S. stellariifolium Franch. A principal component analysis (PCA) based on five leaf traits, an examination of seeds and leaves by scanning electron microscopy (SEM), and a morphological analysis showed that S. danxiacola can easily be separated from S. drymarioides and S. stellariifolium. The conservation status of this species was assessed.
