This differs from the described species of Thryptomene in having only five stamens.—A small, twiggy bush,
with slender branchlets, covered with little opposite leaves, and bearing minute, axiUaiy, white flowers. Branchlets
obscurely four-angled, covered u-ith pale bark. Leaves rather crowded, suberect or patent, 4—4 inch long, thick
and coriaceous, verj- shortly petioled, linear-obovate, blunt, covered with large dots. Peduncles vciy short, bearing
one to three sessde flowers. Calyx 1 line long, obconic, ten-ribbed, ivith two minute deciduous bracts at the base ;
lobes five, orbicular. Petals smaller thau the calj-x-lobes, of the same form, white, persistent. Stamens five, with
short, subidate, iuciuwed filaments, and didjTUOUs anthers with a thickened connective; cells bursting transversely.
Style short. Ovary elongate, with one small cell towards the top, containing two very minute coUateral ovules,
attached to a small placenta near the base of the cell.

A very laige Australian genus, having a very few representatives in other countries, as M. Cajuputi (which
jie ld s the Cajeput oil), in the ila la y an Archipelago. About 130 Australian species are known.—Flowers generaUy
sessile, and often immersed in the substance o f the branch, and visible within it, on a transverse section, at a veiy
early age. Calyx-tCtx hemispherical; limb five-lobed. Petals five. Stamens united into five bundles opposite the
petals, free above. F ru it connate with the branch, and hence persistent for many years, three-eeUed, with many
smaU, angular seeds bursting above. (Name from /xeAas, blacJc, and Xevxos, white ; in aUusioii to the contrast of
the black tnmk and white foUage o f one o f the first described species.)

A common and verj» variable p lan t; Mr. Gimn considers that there are possibly two species confounded under
it, an alpine and lowland one, but I find no difference whatever between these, and he indicates none. Dr. MueUer
sends some very interesting specimens from Yictoria, showing, on the same specimen, broad-ovate, acuminate leaves,
and narrow, Hnear-lanceolate on e s; sometimes the whole of the branches, young shoots, leaves and aU, are liUous.
—A verj- handsome shrub, 2 -4 feet high. Branchlets viUous. Leaves numerous, uniform in size, rigid, curved,
patent, pungent, 4 - 4 inch long, generaUy three-nerved, very variable in breadth. Flowers pale purple or white,
forming terminal heads as large as a marble, which are very vUlous at the base.

Mr. Gunn describes this as one o f the commonest inhabitants o f the marshes, often forming an impenetrable
scrub, most expensive to clear. Trees o f it attain 70 feet, and 4 - 5 feet in girth; one which that naturalist has
measured was unbranched for 27 feet, and was 54 feet in girth at 3 feet above the ground. In poor sandy soü it
forms a dwarf bush. Of the bark, he adds, the natives used to make the Catamarans, or canoes, so admirably
figm-ed iu LabiUardière’s voyage, which were stitched with the bark of Sida pulchella and Plagianthus sidoides.__
Branches covered witb wbite bark, streaked with black lines, perfectly glabrous, as are tbe leaves. Leaves rigid,
very naiTOW-linear, almost acicular, but bluut at the apex, alternate, somewhat recm-ved, 4 - 4 inch long. Floivers
sulphur-yellow, smelling sweet but heavily, in terminal cyHndrical or oblong heads (sometimes with the branch
produced beyond them), an inch or more long.
