robust, much branched herb, 2 -5 feet high, with a strong, peculiar, sweetish smell. Stem robust, tomentose,
branching above into a very large, erect, ovate, decompound panicle, a foot long. Leaves alternate, sessile, half-
amplexicaul, spathulate-lanceolate or oblong-spathulate, acuminate, tomentose below, 3 - 5 incbes long. Branches
of panicle leafy, white with tomentum, slender, ascending. Capitula sessile or pedieelled, tui-binate, 4 inch long,
of many equal, hermaphi’odite, tubular, five-toothed flowers. Involucral scales hnear-oblong, blunt or acute, sca-
rious, hyaline, transparent, in two or three series. Receptacle narrow, with loug, filiform paleæ. Pappus o f slender,
equal, scabrid, soft hairs. Styles with oceasioually three equal arms, each truncate. Achenium small, oblong.

A rather extensive genus, a few species of which are found in New Zealand and New Caledonia, but the majority
belong to Australia, where about a dozen are known, chiefly natives of the east side of the Contment. It so closely
resembles Ozothamnus that it requires close observation to distinguish the species.— Branching shrubs, with small,
evergreen or rusty-coloured, harsh leaves, and terminal panicles or corymbs o f many wbite or pink capitula. Heads
small, nine- to twelve-flowered. Flowers aU tubular, hermaphrodite, or witb a few slender female ones at the circumference.
Receptacle very small, with narrow, hnear, white-tipped scales, like the inner ones of the involucre,
scattered amongst the flowers. Scales o f the involucre numerous, searious, generally pubescent ; outer imbricated ;
inner with white, radiating tips. Anthers with two bristles at the base. Achenium obovate, blunt. Pappus of
one or two series o f slender, soft hairs, which are pilose or thickened at the tips. (Named in honour of M. Henri
Cassini, an eminent French botanist.)

This genus so closely resembles Cassinia that several species have inadvertently been put into one instead of
the other. So far as the Tasmanian species are concerned, they may always be known from Cassinia aculeata by
the absence of paleæ on the involucre ; nevertheless 0 . rosmarinifolius so closely resembles that plant that they may
very readily be confounded. About thirty species of Ozothamnus are known, o f which three inhabit New Zealand,
and all the rest are Australian ; almost all are confined to the south-east parts and Tasmania. The sections into
wliich I have divided the Tasmanian species are by no means natural, but are the most definite I have been able
to construct. (Name from o^w, to scent, and Baixvo?, a bush; from the smell o f some o f the resinous species.)
