Lf-lamina longer than wide, us. broadest about middle with cuneate to subcordate base, upper surface quite glab.; petiole almost glab. except on the margins. Peduncles and calyx-lobes us. almost glab. calyx rarely > 7 mm. long. Outside of corolla, calyx, pedicels, and margins of lvs and petioles often flushed with red.

Type locality: "In gullies on the high lands between Napier and Taupo". Type: K, Mr. H. Hill, 1883.

The Colenso specimen at K has the large lvs mentioned in the original description ("lamina 6 inches long"). Colenso material at W filed with a label in Cheeseman's hand "Ourisia macrophylla Hook. Hawke's Bay uplands, H. Hill. Type of O. robusta Col." includes one flowering and one very old fruiting infl. and a tuft of young lvs, matching the description except that lvs do not exceed 9 cm. in length. W 4168, Herb. Petrie "O. macrophylla Hook. Western Hawke's Bay, H. Hill" could well be part of the same gathering.
