Radical leaves numerous, spreading, ½–l¼ in. long, linear-oblong or linear-spathuiate, acute, narrowed into a short broad petiole, coriaceous, both surfaces clothed with appressed stiff hairs; cauline much smaller, the upper ones sessile. Flowers solitary in the axils of the upper leaves, white, ¼–⅓ in. long, pedicels short. Calyx densely hispid with stiff white hairs, 4-lobed to the middle; lobes linear, acute. Corolla-tube longer than the calyx, throat with 5 scales; limb broad, with 5 rounded lobes. Stamens with very short filaments; anthers very long, linear, their tips projecting considerably above the level of the corolla-scales. Style long, slender. Nutlets oblong, smooth and polished, black.—Exarrhena Colensoi, Kirk in Trans. N.Z. Inst. xxvii. (1895) 351 (in part).

Radical leaves ¾–2 in. long, oblong-spathulate or linear-spathulate, obtuse, narrowed into long petioles, rather coriaceous, hispid on both surfaces; cauline distant, smaller and shorter, sessile, linear-oblong or linear-spathulate. Racemes elongated, many-flowered, hispid with spreading straight or hooked hairs. Flowers yellow or white, ⅕–¼ in. long; pedicels very short. Calyx densely hispid with spreading hooked hairs, divided ¾-way down or more; lobes linear-lanceolate, acute. Corolla-tube funnel-shaped, exceeding the calyx; throat with 5 scales; lobes shore, rounded. Stamens included; anther-tips about level with the corolla-scales. Style shorter than the calyx or very slightly exceeding it. Nutlets narrow-ovoid, polished and shining, black when fully ripe.—''Hook. f. Fl. Nov. Zel. i. 201; Handb. N.Z. Fl. 193; Benth. Fl.
