branches tomentose. Capitula small, about ten-flowered, with long, white, spreading inner involucral scales ; the 
outer pubescent, with broad, membranous margins.

Hab. Not uncommon in various parts of the Colony, as at New Norfolk, Grindelwald, Hobarton, 
etc., A. Cunningham, etc.— (El. Nov.) {v. v.) 
Distrib. South-eastern Australia : Victoria and New South Wales. 
De Candolle describes this as very nearly allied to 0. rosmarinifolius, from which it may be readily distinguished 
by the flat, less rigid leaves, not rough on the upper surface, and very different capitula ; it is much more nearly allied 
to 0. thyrsoideus, but distinguished by the tomentose brancldets, much longer, broader leaves, much larger, more 
branched, rounded, terminal corymbs, and smaller capitula. Some of the Australian specimens have much broader 
leaves than any Tasmanian.— A beautiful shrub, 6-9 feet high. Leaves l|-3 inches long, sometimes | inch broad, 
covered with appressed white tomentum beneath. Capitula very small, with few (six to eight) flowers, narrow 
involucre, and comparatively long white rays.

Very curious, and generally minute, alpine, simple or branching herbs, of which there are several New Zealand 
species ; the genus is best distinguished from Ozothamnus and Gnaphalium by the extremely narrow receptacle. The 
species are often tufted and moss-like, with very small, smooth or woolly, loosely or densely imbricated leaves, and 
solitary terminal capitula sunk amongst the leaves at the ends of the branches.— Heads many-flowered ; outer flowers 
in one row, female, slender, tubular, three- to four-toothed ; inner hermaphrodite, tubular, campanulate, five-toothed. 
Involucre of several rows of erect scales, coriaceous or scarious, often spreading outwards when dry ; inner scales as 
long as the florets, like the outer, or in some species Tadiating, with long or short white liguhe. Receptacle ex- 
tremely narrow, convex, alveolate or fimbrillate or hairy, hidden (even after the flowers have fallen away) by the 
involucral scales, which always connive at the base. Stamens of the disc-flowers five ; anthers with two (sometimes 
fimbriated) tails ; arms of the styles generally protruded, truncated, hispid at the points. Achenia smooth, glan- 
dular, or pubescent.— As a genus, this is not easily defined, except by its size and habit ; it differs from Ozothamnus 
in the regular series of female flowers ; from Helichrysum by its habit, and very narrow receptacle ; from Gnaphalium 
by the same characters. (Named in honour of the late M. M. B. Raoul, surgeon in the French navy, author of the 
excellent ' Choix de Plantes de la Nouvelle-Zelande.')
