be recognized by tbe broad petiolate leaves aud globular corymbs, wliich sometimes become diseased and form
round balls of silky wool, with brown scales interspersed (probably due to the punctiu-e of an insect). The plant
was first described as a Swammerdammia (by M. Raoul), a genus I do not retain.

A small, hoaiy, half-berbaceous shrub, a foot high, with woody branching stem, as thick as a crow-quill, and
short silvery branches, covered with small, closely appressed, inconspicuous scale-like leaves. Leaves ovate, thick
aud coriaceous, blunt, smooth at the back, and marked with an oval spot below the tip, densely woolly on the upper
surface (next the stem), 4—I line long. Heads terminal, sobtary at tbe tips of tbe branches, 4 inch long, broadly
oblong. Involucral scales scarious, bnear, blunt. Florets very numerous, yellow. Achenia pubescent.—A cmdous
plant, albed to the 0. lepidophyllus of Tasmania, but much smaller, and with sobtary heads of flowers.—

Very similar in habit and general appearance to 0. microphyllus, but more straggbng. Stems very woody,
prostrate, as are the larger branches, the smaller ones erect or ascending, leafy, all covered with a closely appressed
silvery-grey pubescence. Leaves densely imbricated, narrow linear, blunt, silky at the back, woolly on the face,
appressed to the stem, 1 line long. Capitula narrower and rather longer than in the former species. Florets also
longer; pappus very white, silky, and of slender hairs. Achenia quite smooth, ribbed or angled.—Plate XXXY.R.

Note. Ozothamnus pinifolius, Br. (Calea pinifolia, Forst.), is only known through a very indifferent specimen
in Forster’s Herbarium, to which the habitat of New Zealand is marked by that author with a mark of doubt. As
it has been found by no succeeding collector, I am inclined to suspect it to be more probably a New Caledonian
plant. It may be recognized by its very narrow aceróse leaves, spreading on all sides, and its scarred branches,
exactly like those of a Pine.

Very curious, and generally minute, alpine, simple or branching herbs, often tufted and moss-like, with veiy
small, smooth or woolly, loosely or densely imbricated leaves, and sobtary terminal beads, sunk amongst the leaves
at the ends of the branches. Heads many-flowered ; outer florets in one row, female, slender, tubular, three- to four-
toothed ; inner liermaphrodite, tubular, campanulate, five-tootbed. Involucre of several rows of erect scales, coriaceous
or scarious, often spreading outwards when dry ; inner scales as long as tbe florets, and, like tbe others, in some
species radiating with long white ligulæ. Receptacle extremely naiTow, convex, alveolate or fimbrillate or hairy,
hidden (even after the florets have fallen away) by the involucral scales, which always connive aFthe base. Stamens
of tbe disc-florets five ; anthers witb two (sometimes fimbriated) tails ; arms of tbe styles generally proti-uded,
truncated, hispid at the points. Achenia smooth, glandular, or pubescent.—The very inconspicuous plants forming
this genus are difficult of discrimination, without great care and a magnifying glass. As a genus, it is not easily
defined, except by its size and habit : it differs from Ozothamnus iu tbe regular series of female florets ; from Heli-
chrysum by its habit, and very narrow receptacle; from Gnaphalium by the same characters. (Named in honour of
if. M. E. Raoul, surgeon in tbe French navy, author of tbe excellent ‘ Choix de Plantes,’ repeatedly quoted.)

H a b . Throughout the Islands, in dry rocky places, and on the mountains ; origmally detected by Mr.
Bidwill on Tongariro ; I bave not seen specimens from north of the East Cape.
Stems -g- 14 inch high, most densely tufted, branched ; branches closely covered witb small, coriaceous, densely
imbricating leaves. leaves 1-3 lines long, patent, recurved, spathulate, blunt, very concave above, generally thickly
covered with white or yellow wool. Heads terminal, small. Involneral scales often spreading when dry, conniving at
the base ; the outer coriaceous, woolly ; inner smooth, scarious, white or sulplmr-yellow.—This beautiful little plant
varies much in. the size of tbe leaves, which are sometimes so small that the whole plant resembles a moss ; it is of
a pale sulphur-colour.

Hab. Northern and Middle Islands ; on mountains, etc., Colenso, Bidwill.
Similar in most respects to R. australis; but much more slender, and with longer, less densely-tufted stems.
Branches short or long, sometimes trailing for 6-8 inches, slender, sparingly leafy. Leaves spreading, linear-oblong
or nearly lanceolate, sharp or apiculate, rather thick and coriaceous, more or less silky or wooUy on one or both
surfaces, sometimes smootli, except towards the point at the back, 1-2 lines loug. Heads tenninal, a good deal
larger thau the leaves, 4 inch long. Involucral imbricated ; outer woolly, coriaceous; iuuer scarious and
hyaline, with brown tips ; none radiating beyond the others, or white.—I have seen (and figured) au hermaphrodite
flower of this species with three arms to the style.—P la te XXXVI. A. Fig. 1, 2, leaves ; 3, floret of tbe ray ;
