Herbs, chiefly natives of western North and South America, also of Northern India and Australia —Erect or 
procumbent. Leaves opposite. Peduncles axillary or terminal, one-flowered, without bracts (except in M.? radicans); -

valves falling away from a central seed-bearing column. (Name, mimulus, a little mask, which the flowers resemble.) 
1. Mimulus repens, Br.; repens, foliis sessilibus v. amplexicaulibus ovatis oblongisve obtusis, pedun-

Has. Throughout the Islands, common. East coast, Colenso. Nelson, Bidwill. Akaroa, Raoul, Lyall. 
A perfectly smooth, succulent, creeping, small herb. Stems 2-4 inches long, spreading over muddy and 
marshy places, or suberect. Leaves small, 2—4 lines long, rather fleshy, orbicular, quite entire, sessile. Flowers 
axillary; peduncles longer than the leaves or very short. —Calyz bell- or funnel-shaped, becoming hemispherical, 
truncate, the mouth obscurely lobed. Corolla large, blue or pink —Not an uncommon Tasmanian species. 
2. Mimulus? radicans, Hook. fil.; caule repente radicante ramulos foliiferos erectos emittente, foliis 
paucis petiolatis oblongis obtusis integerrimis pilosis glabratisve, pedunculis terminalibus 1-2-floris, calyce 
campanulato laxe patentim piloso, corolla ampla, staminibus 2 inferioribus corolle tubum zequantibus, 
superioribus brevioribus. 
Has. Northern Island. Tararua Mountains and Wairarapa Valley, Colenso. 
A very curious species, of which I have not seen the fruit. Stems stout, creeping and rooting, a few inches 
long, with short erect branches } inch high, bearing a few petiolate leaves and one or two large flowers. Leaves 
petiolate, 4-3 inch long, oblong, blunt, entire, smooth or hairy, blotched green and brown. Peduncles erect, with 
a subulate bract, glabrous or hairy. Flowers 4-3 inch long. Calyx bell-shaped, five-lobed, covered with white 
spreading jointed hairs. Stamens four. Style with two oblong blunt lobes.—The genus of this plant is doubtful. 
Gen. III. MAZUS, Lour. 
Calya late campanulatus, 5-fidus. Corolla labium superius erectum, ovatum, breviter bifidum, inferius 
multo majus, patens, trifidum; fauce bigibbosa. Stamina fertilia 4; antherarum loculi contigui, 
divaricati. Stylus apice bilamellatus; laciniis ovatis, eequalibus. Capsula globosa v. compressa, obtusa, 
loculicide bivalvis, valvulis integris. Placente crasse, subcarnosw. Benth. in DC. Prodr. 
A small genus, found in the mountains of India, the Malay peninsula and islands, and one species in Tasmania, 
which also inhabits New Zealand. The M. Pumilio is an extremely variable plant in size of leaf and flower and 
length of peduncle, and is smooth or hairy. Stems very short, rising from a long underground creeping rhizoma. 
Leaves radical, 1-4 inches long, linear, obovate-oblong or spathulate, blunt, entire or sinuate and toothed. Scapes 
shorter or longer than the leaves, sometimes 5 inches long, one- to five-flowered, racemose or paniculately branched ; 
pedicels slender, 4-13 inch long, erect, patent or recurved, each with a subulate bract beneath the flower. Calyx 
campanulate, five-toothed, much shorter than the corolla. Corolla 2-2 inch long, pale blue; upper lip curved back, 
a little bifid; lower very large, three-lobed; mouth with two swellings. Stamens four; anther-lobes spreading. 
Style with two flat plates at the top. Capsule globose, compressed, blunt, loculicidal.—A. common plant in Tas- 
mania; always variable. (Name from pacos, a breast; from the swellings on the throat of the corolla.)
