Racemes short, simple or forked. Flowers very shortly pedicelled. Calyx ¼ in. long, hispid with appressed or patent, simple and hooked bristles. Corolla ⅙–¼ in. long; tube cylindric, longer than the calyx; lobes short, rounded. Stamens with long slender filaments; anthers linear. Nuts broadly ovate or orbicular, very black and shining."—Exarrhena Lyallii, ''Hook. f. Handb. N.Z. Fl.'' 196. ?? Myosotis (Exarrhena) oreophila, Petrie in Trans. N.Z. Inst. xxviii (1896) 539.

Racemes many-flowered, simple or forked, at first short and almost capitate, but elongating as the flowering advances. Flowers large, crowded, ½–⅔ in. long, bright pale-yellow or more rarely white with a yellow eye, sweet-scented, pedicellate. Calyx covered with appressed silky hairs, 5-partite; lobes linear-lanceolate, obtuse. Corolla broadly funnel-shaped; tube short, hardly exceeding the calyx, throat with 5 scales; limb large, rather longer than the tube, deeply lobed; lobes oblong-ovate, obtuse or acute. Stamens with very slender elongated filaments; anthers exserted beyond the corolla-lobes. Nutlets ovoid, red-brown, but not seen quite ripe.
