"Engel and Merrill (2010) described P. circumdentata var. carinata J.J.Engel & G.L.Merr. for plants with deltoid-ovate leaves with a distinctly ampliate base and margins typically sharply ciliate-dentate especially at the extreme dorsal and ventral base. Plants with this leaf morphology also have entire male bracts. Plagiochila circumdentata var. circumdentata by contrast has leaves ovate to subreniform, with a less distinctly ampliate leaf base and leaf margins more sparsely and distantly toothed to subentire, male bracts have a weakly toothed apex. ...I therefore agree with Engel and Merrill (2010) that the recognition of two varieties within P. circumdentata is warranted"
