''Pyxidanthera brevifolia,'' the littleleaf pixiemoss or sandhills pyxie-moss, is a plant species known only from North Carolina and South Carolina. It occurs in deep, sandy soil such as sand hills and sandy ridgetops, sometimes in open pine-oak woodlands, at elevations of .〔(Flora of North America v 8 p 337 )〕 ''Pyxidanthera brevifolia'' is closely related to the more widespread ''P. barbulata'', and some authors have suggested considering the two as a single species. For the moment, though, Flora of North America〔 and the Kew Gardens Plant List 〔(Kew Gardens Plant List )〕 both accept ''P. brevifolia'' as a distinct species. The two can be distinguished by the leaves. Leaves of ''P. brevifolia'' are shorter than those of ''P. barbulata'', rarely more than 4 mm long. They also lack the marginal cilia characteristic of ''P. barbulata'', and are more intensely woolly on the underside.〔Wells, Bertram Whittier.
