The specimens seen by me are constant in the differentiating characters indicated. Martin (T.R.S.N.Z. 65, 1935, 181) remarks: "This chasmophyte has been named in honour of Mr. J. H. Hadfield, who has not only assisted me greatly in this research, but has also done more than anyone else to introduce this plant to the notice of New Zealand botanists."
