XXXIX. COMPOSITE. 
147 
Middle Island : Nelson mountains, banks of streams, Clarence and Wairau valleys, alt. 
3-5000 ft., Bidwill, Sinclair , Travers, Great Tasman glacier and elsewhere, on shingle 
beds in the Southern Alps, Haast, and Otago mountains, Hector and Buchanan. 
4. O. coralloid.es, Hook. f. FI. N. Z. ii. 332. A very remarkable, 
woody, short, stout, branched shrub. Branches (with the leaves on) cylindric, 
as thick as the finger, the leaves resembling tubercles on their surface. Leaves 
in very numerous series, closely and densely imbricating, oblong, obtuse, 
■g-j in. long, upper part very thick, convex and shining, lower part mem- 
branous; surface next to the stem densely clothed with white cotton. Head 
small, solitary, hidden amongst the uppermost leaves at the tip of the branch ; 
involucral scales linear, recurved, with membranous tips. 
Middle Island: Kaikora mountains, ATBonald; Upper Awatare valley, Sinclair. 
5. O. Selago, Hook. f. FI. N. Z. i. 332. A good deal similar to 0. 
corattoides, also very stout and woody, but intermediate between it and 
0. micro phi/llus. Branchlets with leaves on -g- in. diam. Leaves imbricating 
in 5 or 6 series, oblong-ovate, obtuse, or subacute, trigonous, the exposed part 
of back keeled, shining, surface next the stem densely cottony. Heads ter- 
minal, solitary, sessile, exposed ; involucral scales linear-oblong, obtuse, lower 
half coriaceous, upper scarious. 
Middle Island : Kaikora mountains, ATBonald, Sinclair. 
13. RAOULIA, Hook. f. 
Very small, generally tufted (often most densely), alpine and subalpine, 
slender, or rigid and stout herbs. Leaves minute, usually silky woolly or 
cottony, often most densely imbricated. Heads small, terminal, sessile. — 
Involucre oblong ; scales scarious, in 2 or 3 series, the inner often white and 
radiating. Receptacle very narrow, papillose or fimbrillate. Florets of cir- 
cumference in 1 or 2 series, female; corolla filiform, 3- or 4-toothed; arm of style 
exserted. Florets of disk numerous, hermaphrodite ; corolla funnel-shaped 
above ; anthers with slender tails ; arms of style shorter. Pappus of 1 row 
of slender or stout scabrid hairs, sometimes thickened at the tips. Achene 
small, oblong. 
A genus founded on liabit more than on any good characters that can separate it from 
Gnaphalium, section Helichrysum ; its herbaceous habit distinguishes it from Ozothamnus. 
It contains two natural and most distinct sections, of which one, containing R. subulata , exi- 
mia, grandijlora,mammillaris , and bryoides has a convex, often hispid receptacle; achenes with 
very long, silky hairs, a thickened areole at their base ; and stout, rigid, opaque pappus 
hairs, thickened at the tip ; these probably constitute a good genus, to which the name 
Raoulia may be retained : the others may perhaps fall into Gnaphalium or Helichrysum , 
but until all the Gnaphalioid Compositce are worked up, it is impossible to settle the limits 
of the^genera. I at one time suspected that the white radiating involucres indicated sexual 
differences, bnt I have failed to prove this. The style has often 3 arras in this genus. 
Helichrysum Youngii, has much the habit of a Raoulia , but more that of the genus I have 
placed it in.
