G. pleurogynoides var. rigida Kirk in T.N.Z.I. 27, 1895, 335 is represented by 2 sheets in Herb. Kirk; there are 2 slender, possibly young, plants matching G. corymbifera, and 1 much smaller resembling G. serotina.

Cheeseman (Man. N.Z. Fl. 1925, 731) remarks: "Mr. Brown informs me that it corresponds with the G. saxosa var. γ of the Handbook, and I suspect that it also includes a part of the G. pleurogynoides of the same work. At any rate, it is the plant which New Zealand botanists have been accustomed to call G. pleurogynoides. The true G. pleurogynoides was founded on Tasmanian specimens, and has not yet been satisfactorily matched with any New Zealand plant."

Hooker (Handbk N.Z. Fl. 1864, 191) gives for G. saxosa var. γ : "Stems erect, very stout, simple, sparingly leafy. Leaves often large, thick, and fleshy. Flowers very numerous, large, corymbose. Calyx short, divided to the middle; lobes ovate-acute or acuminate. (Like G. pleurogynoides, but perennial, and calyx very peculiar, unlike any except some forms of var. α" Var. α is G. bellidifolia figured in Ic. Pl. t. 635.
