2. M. radicans, Cheesem.—Stems creeping and rooting at the joints, often subterranean, putting up short erect leafy branches 1–3 in. high. Leaves close together, spreading, petiolate, ¾–2 in. long including the petiole, obovate or linear-obovate, obtuse, gradually narrowed into the petiole, entire or very obscurely sinuate, pilose or almost glabrous. Peduncle terminal, 1–3-flowered, usually longer than the leaves; pedicels with 1 or 2 linear-subulate bracts. Flowers large, ½–¾ in. long, white with a yellow centre. Calyx campanulate, 5-cleft, not angled, pilose with jointed hairs. Corolla-tube much exceeding the calyx; upper lip erect; lower lip much larger, spreading. Capsule ⅓ in. long, ovoid, enclosed in the persistent calyx.—Mimulus radicans, Hook. f. Fl. Nov. Zel. i. 188; Handb. N.Z. Fl. 202.

Imperfect specimens of this were described by Sir J. D. Hooker as a Mimulus. It has, however, the habit, inflorescence, and calyx of Mazus, and I have consequently transferred it to that genus.
5. GRATIOLA, Linn.
Herbs, glabrous or glandular-pubescent. Leaves opposite, entire or toothed. Flowers axillary and solitary, 2-bracteolate. Calyx deeply 5-partite; segments nearly equal. Corolla-tube cylindric; lips spreading, upper entire or 2-fid, lower 3-fid. Perfect stamens 2, included; anther-cells distinct, parallel; staminodia or barren stamens 2, filiform, sometimes wanting. Style filiform; stigma dilated and deflexed, entire or 2-lamellate. Capsule ovoid, loculicidally or septicidally dehiscent, 4-valved, valves separating from a columnar placentiferous axis. Seeds numerous, small, reticulate.
A genus consisting of about 25 species, scattered over the temperate and subtropical portions of both hemispheres. One of the New Zealand species has a wide range in Australia and extra-tropical South America; the other extends to Victoria and Tasmania alone.
