Kirk (Stud. Fl. 1899, 162) described his var. intermedia from material collected by him on Rangitoto Id: "Twigs much stouter. Leaves excessively coriaceous, ovate-lanceolate. Cymes small. Pedicels and peduncles short and stout." Carse (T.N.Z.I. 50, 1927, 92) gave a description of his × M. sub-tomentosa, based on specimens from Lake Taupo, Whau Creek, and Titirangi. The parent spp. were M. excelsa and M. robusta. Cooper (Rec. Auck. Inst. Mus. 4, 1954, 205-212) made detailed studies of specimens in the Cheeseman Herbarium and of two mass collections on Rangitoto Id. It is clear that the crossing of the two spp. results in a polymorphic series of hybrids. Carse's No. 935/2, "amongst scrub, Titirangi, 22/5/22" in CM is taken as the type of × M. sub-tomentosa.
