A taxonomic reassessment of Styphelia cuspidata (R.Br.) Spreng. (Ericaceae) with the description of two new species S. cognata A.R.Bean and S. lucens A.R.Bean

A morphological reassessment of specimens identified as Styphelia cuspidata (R.Br.) Spreng. (syn. Leucopogon cuspidatus R.Br.) has revealed the existence of three taxa that differ at species rank. In this paper, these three species, all endemic to Queensland, are described, compared and illustrated. Two new species, Styphelia cognata A.R.Bean and S. lucens A.R.Bean are named.
