134 FLORA OF NEW ZEALAND. [ Composite. 
be recognized by the broad petiolate leaves and globular corymbs, which sometimes become diseased and form 
round balls of silky wool, with brown scales interspersed (probably due to the puncture of an insect). The plant 
was first described as a Swammerdammia (by M. Raoul), a genus I do not retain. 
$ b. Capitula solitary. Leaves very minute, appressed to the stem. 
2. Ozothamnus microphyllus, Hook. fil.; fruticulus decumbens, ramosus, incanus, ramis divaricatis 
prostratis, ramulis ascendentibus, foliis minimis arcte imbricatis ramis appressis ovatis obtusis crassis coria- 
ceis dorso glaberrimis convexis infra apicem cicatricatis intus superne lanuginosis, capitulis majusculis 
solitariis ramulis abbreviatis terminalibus sessilibus, involueri squamis coriaceis margine scariosis, flos- 
culis plurimis, receptaculo plano, acheniis pilosis. Tas. XXXV. 4. 
Has. Middle Island. Nelson; stony places, Warrau Pass, 4000 feet elev., Bidwill. 
A small, hoary, half-herbaceous 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 
and 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—4 line long. Heads terminal, solitary at the tips of the branches, 4 inch long, broadly 
oblong. Involucral scales scarious, linear, blunt. Florets very numerous, yellow. Achenia pubescent. —A curious 
plant, allied to the 0. lepidophyllus of Tasmania, but much smaller, and with solitary heads of flowers.—

3. Ozothamnus depressus, Hook. fil.; fruticulus decumbens, ramosus, sericeus, ramis prostratis, ramu- 
lis brevibus ascendentibus subvirgatis ultimis dense foliosis, foliis arcte imbricatis caule appressis lineari- 
ligulatis obtusis crassis coriaceis superne villosis dorso sericeis convexis, capitulis ramulis brevibus ter- 
minalibus solitariis, involucri anguste oblongi squamis linearibus scariosis obtusis, acheniis costatis 
glaberrimis. Tas. XXXV. B. 
Has. Middle Island. Nelson; banks of streams at Warrau Pass, 2250 feet elev., Bidwill. 
Very similar in habit and general appearance to 0. microphyllus, but more straggling. 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. FYorets also 
longer; pappus very white, silky, and of slender hairs. Achenia quite smooth, ribbed or angled.—PLATE XXXV. B.

Norn. 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 acerose leaves, spreading on all sides, and its scarred branches, 
exactly like those of a Pine.
