200 FLORA OF TASMANIA. [Composite. 
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 inches long. Branches 
of panicle leafy, white with tomentum, slender, ascending. CapiMa sessile or pedicelled, turbinate, \ inch long, 
of many equal, hermaphrodite, tubular, five-toothed flowers. Involucral scales linear-oblong, blunt or acute, sca- 
rious, hyaline, transparent, in two or three series. Receptacle narrow, with long, filiform palese. Pappus of slender, 
equal, scabrid, soft hairs. Styles with occasionally three equal arms, each truncate. Achenium small, oblong. 
(Name from uttoAos, tender, and X W^> an integument; in allusion to the membranous involucre.) 
Gen. XIX. CASSINIA, Br. 
Capitulum pauci-(9-12)-florum; floribus omnibus hermaphroditism tubulosis, v. paucissimis ambitu 
fcemineis, angustis. Receptaeulum angustum, paleaceum; paleis distinctly linearibus, floribus immixtis, 
apicibus interdum radiantibus albidis. Involucri squama multiseriatae, scariosre, exteriores imbricate, 
breves, interiores ssepissime elongate, apicibus albidis. Stigmata obtusa, hispidula. Anthem inclusa3, basi 
bisetffi. Achenium obovatum, erostre. Pappus 1-2-serialis ; setis plurimis filiformibus, apice incrassatis 
ant pemcillatis.— Fruticuli v. arbuscufi; foliis sparsis, sapius linearibus, marginibus revolutis ; corymbis 
terminalibus, interdum paniculatis. 
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 Continent. 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 of many white or pink capitula. Heads 
small, nine- to twelve-flowered. Flowers all tubular, hermaphrodite, or with a few slender female ones at the cir- 
cumference. Receptacle very small, with narrow, linear, white-tipped scales, like the inner ones of the involucre, 
scattered amongst the flowers. Scales of the involucre numerous, scarious, 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 of slender, soft hairs, which are pilose or thickened at the tips. (Named in honour of M. Henri 
Cassini, an eminent French botanist.)

Distrib. South-eastern Australia, from New South Wales to Melbourne. 
A handsome shrub, 3-5 feet high, covered in summer with a profusion of corymbs of white capitula.-^m* 
and branches and under side of leaves covered with hoary pubescence or tomentum. Leaves 1-2 inches long, 
spreading, bnear ; margins revolute generally to the midrib, upper surface hispid or minutely aculeate. Inner scales 
of the involucre erect, not radiating. 
Gen. XX. OZOTHAMNUS, Br. 
Omnia Cassinia, sed receptaeulum epaleaceum, et involucri squamis interioribus plensque radiantibus. 
This genus so closely resembles Cassinia that several species have inadvertently been put into one instead of 
ie o her. So far as the Tasmanian species are concerned, they may always be known from Cassinia aculeata by 
the absence of pale* on the involucre ; nevertheless 0. rosmarinifoUus so closely resembles that plant that they may
