A small but widely diffused genus of littoral trees, growing hke Mangroves {RhizopJwra) in tidal estuaries of
most warm countries, and as such famUiar to all travellers.—Aoofs woody, spreading, standing out of the mud
and over-arching in entangled masses, sending up multitudes of Asparagus-like shoots from their underground parts.
Branches, young ones spreading, pubescent. Leaves opposite, evergreen, petiolate, ovate or oblong, quite entire,
blunt, pubescent below, coriaceous, 2 -3 inches long. Bhwers iu threes, silky, i inch long, collected in trichotomous’
panicles, crowded, each with three ovate silky bracts. Oalyx of five rounded lobes. CoroUa coriaceous, shortly campanulate,
four-lobed. Stamens four. Ovary two-ceHed, with two pendulous ovules in each cell. Style short, bifid.__
After fecundation oue ovule commences to germinate as the seed ripens, and the others become obliterated. OotyU-
£&«» conduphcate. two-lobed; radicle iomentost; plumule two-leaved. (Named in honour of ftm'ce»»«, the cele-

Owing to some mistake, this plant has been reputed as yielding a gum in New Zealand, whence the trivial
name resinifera was given it. I t is also a native of Australia, as far south as Bass’s Straits, and of the Tropics of
both worlds.

The genus Mentha, to which the Peppermint, Spearmint, etc. belong, is widely diffused, especially in the
temperate countries of the Northern Hemisphere, but is very sparingly represented in the Southera. A few species
inhabit Australia, Tasmania, and one New Zealand, M. Cunninghamii: it is a fragrant, small, sleuder, diffuse,
branching herb, with pubescent four-angled branches, opposite leaves, and axillary solitary flowers. Leaves dotted
below, petiolate or sessile, rounded or ovate, blunt, quite entire, ^ i^^h long, including the petiole. Pedicels as
long as the petiole, or longer. Flowers erect, 2g- lines long. Calyx campanulate, five-toothed, striated, hairy,
villous ou the teeth. Corolla bell-shaped, with a short tube and five unequal rounded lobes. Stamens included.

Herbs or small shrubs, natives of almost all parts of the world except South Africa; but very few species ai’e
found in Australia and Tasmania, including however the present S. humilis, a very variable plant both in Australia
and New Zealand, in the form of leaf and size of flower. A straggling, procumbent, or erect slender herb, 4 inches
to 1|- feet long. Stems faintly downy. Leaves petiolate, in scattered pairs, F— inch long, oblong or rounded, blunt,
sometimes cordate, entire, distinctly toothed or lobed. Flowei's white, \ inch long, on solitary, axifiary, one-flowered
pedicels, as long or longer thau the petiole. Calyx much enlarged and closing over the fruit, of two entire lips,
without bracts, glabrous; upper arched, with a scale or gibbosity above. Corolla two to three times longer than the
calyx, downy, tubular, two-lipped; upper lip three-toothed, galeate; lower three-lobed, the middle one notched.
