29. 0. chathamica 7. Kirk in Trans. N.Z. Inst. xxi (1891) 444,— 
A rather stout branching shrub 3-6ft. high; branches, leaves beneath, and 
peduncles densely clothed with soft white tomentum. Leaves 1-3 in. long, 
1-11in. broad, very variable in shape, lanceolate or elliptic-lanceolate to 
oblong-ovate or oblong-obovate, acute, narrowed into a short broad petiole, 
very thick and coriaceous, closely serrate with short blunt callous teeth ; 
midrib and chief veins usually visible beneath. Peduncles few at the tips 
of the branches, usually exceeding the leaves ; bracts few, linear or 
lanceolate. Heads solitary, large, 14-1?in. diam.; involucral scales more 
or less concealed with white cobwebby tomentum. Ray-florets lgulate, 
white or purplish; disc-florets violet-purple. Achenes linear, curved, 
slightly pubescent.—Students’ Fl. (1899) 264; Cheesem. Man. N.Z. Fl.

Closely allied to both O. operina and O. angustifolia, but differing in the broader 
leaves, much more slender peduncles, and fewer bracts. It is separated from 
QO. semidentata by its more robust habit, broader and more coriaceous leaves, and 
larger flower-heads, the ray-florets of which ate usually white.

3. O. operina,Hook. f. Fl. Nov. Zel. i (1853) 114.—A stout sparingly 
branched shrub 6-12 ft. high; branches, leaves beneath, peduncles, and 
inflorescence densely clothed with soft white tomentum. Leaves often 
crowded at the tips of the branches, spreading, 2-4in. long, 3-3 in. 
broad, narrow obovate-lanceolate, acuminate, eradually narrowed into a

margins with numerous close blunt teeth with callous tips. Peduncles 
crowded at the ends of the branches, 1-3in. long, stout, densely clothed 
with numerous closely imbricating lanceolate or linear obtuse bracts. 
Heads large, 1-Idin. diam.; involucral scales in 2-3 series, tomentose. 
Ray-florets white ; disc-florets yellow. Achenes din. long, linear, con-

shorter than the leaves, clothed with laxly imbricating foliaceous bracts, 
white beneath. Heads large, 14-2in. diam.; involucral scales in 2 
series, the outer densely tomentose. Ray-florets white : disc-florets purple. j
