Type locality: Auckland Is. Type: K, "pebbly beach", Hooker.

Hooker (loc cit.) remarks: "Planta maritima paulo diversa, humilior, crassior, foliis minoribus petiolis superne, stipulisque majoribus setosis". Specimens collected on recent excursions suggest that the differences are due to habitat. In K there is a specimen of Bidwill's "south end, N. Zealand" attributed in the Handbook to "Northern Island, southern extreme".
