1. O. maerocarpa Hook. f. Fl. Nov. Zel. 1 (1853) 198.—Stems stout, 
erect from a short thick creeping rhizome, 9-24in. high, purplish below, 
glabrous or with faint hairy lines decurrent from the bases of the bracts. 
Radical leaves numerous, on stout petioles 2-8in. long; blade 15 in,, 
broadly oblong or orbicular, cordate or subcordate at the base, crenate, 
dark-green above, paler beneath, very thick and coriaceous, quite glabrous 
except the margins towards the base, which are ciliate. Flowering stem 
stout. Cauline leaves 1 or 2 pairs, ovate or oblong, almost connate at the 
base, sessile. Inflorescence of 4-8 superposed whorls of pedicelled flowers. 
Bracts 3-6 in a whorl, oblong or oblong-lanceolate, coriaceous, crenate. 
Flowers large, 3-1 in. diam., white; pedicels 1-3in. long. Calyx deeply 
5-partite ; segments Lin. long, linear-oblong, obtuse, coriaceous, glabrous 
or the margins alone ciliate. Corolla-tube short and broad, villous within ; 
lobes obovate, retuse. Capsule $-din. long, ovoid-oblong—Handb. N.Z.

Var. calyeina Cockayne in Trans. N.Z. Inst. xlviii (1916) 198.—Leaves ovate or 
ovate-oblong, with a more or less cuneate base, never orbicular with a cordate base. 
Petiole hardly as long as the blade. Crenatures of the leaf smaller. Bracts larger, 
and peduncles stouter.—O. calycina Col. in Trans. N.Z. Inst. xxi (1889) 97. 
Soutn Istanp: The typical state not uncommon in the sounds of the south-west 
coast of Otago, Lyall, Hector and Buchanan / and others; Clinton Saddle, Cockayne ! 
F. G. Gibbs! Var. calycina: Abundant on the central chain of the Southern Alps, 
from Arthur’s Pass southwards to the Franz Josef Glacier. Sea-level to 3500 ft. 
November—January. 
The finest species of the genus. It is allied to the following, but is easily separated 
by the much stouter and more coriaceous habit, by being nearly glabrous, and by the 
larger flowers and capsules. ? 
Dr. Cockayne’s discovery that the south-western form of the species differs from 
that found in the central portion of the Southern Alps is most interesting, and shows 
what a small advance has been made in our knowledge of the flora of the Otago sounds 
during the last 60 years. 
2. QO. macrophylla Hook. Ic. Plant. (1848) tt. 545, 546.—Hrect from a 
short stout decumbent rhizome, 6-24 in. high, more or less pubescent or pilose 
with soft spreading hairs, rarely almost glabrous. Radical leaves variable
