and on clifis, H. H. Travers! Enys! Cox! Keketerehe. Noyember-

distinct in the broader leaves and more slender peduncles with fewer bracts. 
4. O. operina, Hook. f. Fl. Nov. Zel. i. 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—4 in. 
long, 4-#in. broad, narrow obovate-lanceolate, acuminate, gradually 
narrowed into a short winged petiole, rigid, very thick and coria- 
ceous, glabrous above; margins with numerous close blunt teeth 
with callous tips. Peduncles crowded at the ends of the branches, 
1-3 in. long, stout, densely clothed with numerous closely imbricat- 
ing lanceolate or linear obtuse bracts. Heads large, 1-14 in. diam. ; 
involucral scales in 2-3 series, tomentose. Ray-florets white; disc- 
florets yellow. Achenes +in. long, lear, conspicuously ribbed, 
silky.— Handb. N.Z. Fl. 124; Kirk, Students’ Fil. 264. Arnica

to the base, sessile, extremely rigid and coriaceous, glabrous and 
glossy above, irregularly finely crenate-dentate, teeth with hard

beneath. Heads large, 14-2in. diam.; involucral scales in two 
series, the outer densely tomentose. Ray-florets white; disc- 
florets purple. Achenes linear, grooved, silky.—Handb. N.Z. Fl.
