1. E. cuneata, Forst. Prodr. n. 234.—Perennial, 6–30 in. high or even more; stems erect or decumbent, firm, sometimes almost woody at the base, usually much branched and often excessively so, rarely simple; branches slender, virgate, leafy, puberulous or rarely almost glabrous. Leaves variable in size and shape, ⅕–⅔ in. long, broad or narrow obovate-cuneate, rounded at the tip, narrowed at the base into a distinct petiole of variable length, coriaceous, glabrous, with 1–3 more or less distinct notches on each side, rarely entire; margins flat, not recurved. Flowers usually very numerous, in large specimens from the repeated branching of the flowering stems and the reduction of the upper leaves to bracts forming a quasi-paniculate inflorescence, in smaller forms spicate; peduncles shorter than the calyx. Calyx small, narrow, 4-lobed; lobes obtuse, shorter than the tube. Corolla large, ½–¾ in. long, white with a yellow eye, sometimes with purplish streaks, pilose externally; upper lip 2-lobed, lobes emarginate; lower lip 3-lobed. Capsule linear-cuneate, emarginate, hairy or at length glabrous, exceeding the calyx. Seeds numerous, elongate.—A. Rich. Fl. Nouv. Zel. 191; A. Cunn. Precur. n. 384; Raoul, Choix, 43; Hook. f. Fl.

North Island: From the East Cape and Taupo southwards to Cook Strait, not uncommon. South Island: Has been recorded from several stations from Nelson to Otago, but I have seen no specimens which I can refer to it. Sea-level to 4500 ft. December–March.
A distinct species, well marked by the large size, much-branched perennial habit, cuneate leaves narrowed into a distinct petiole, large pedicelled flowers, and long narrow capsule. There seems to be two main varieties—one tall and slender, with numerous leafy branches, narrow long-petioled leaves, and copious inflorescence; the other, which is principally montane or subalpine, and which
