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. 
2. O. macrophylla, Hook. Ic. Piant. t. 545, 546.—Erect from 
a short stout decumbent rhizome, 6—24in. high, more or less 
pubescent or pilose with soft spreading hairs, rarely almost gla- 
brous. Radical leaves variable in size and shape, on long petioles ; 
petioles 1-6in. long, stout or slender, sheathing at the base; blade 
1-5 in., ovate or ovate-oblong to orbicular-oblong, obtuse, oblique 
and cordate or cuneate at the base, crenate, rather thin and mem- 
branous, sparsely pubescent or almost glabrous. Flowering-stem 
erect, rather stout or slender. Cauline leaves 1 or rarely 2 pairs, 
ovate, sessile. Inflorescence of 3-7 superposed whorls of pedicel- 
late flowers, in small varieties sometimes reduced to a few-flowered 
terminal umbel. Bracts 3-8 in a whorl, linear-oblong or linear- 
obovate to linear, crenate. Flowers large, $-2in. diam., white or 
white with purplish streaks; pedicels 4-2in. long, slender, erect. 
Calyx deeply 5-partite ; segments tin. long, lanceolate or linear, 
glandular-hairy. Corolla-tube slightly curved, villous within; lobes 
obovate, retuse. Capsule +in. long, ovoid-oblong, turgid, mem- 
branous.—Hook. f. Fil. Nov. Zel. 1. 197; Handb. N.Z. Fil. 218. 
O. robusta, Col. in Trans. N.Z. Inst. xvii. (1886) 246. 
NorrH anp Souty Isuanps, Stewart Istanp: Not uncommon in damp 
mountainous localities from Moehau (Cape Colville) southwards. Sea level to 
4500 ft. November-—January. 
In its fully developed state this is an exceedingly handsome plant. It is 
perhaps nowhere more abundant than on Mount Egmont, where it was origin- 
ally discovered by Dieffenbach. 
3. O. Colensoi, Hook. f. Handb. N.Z. Fil. 218. — Rhizome 
slender, creeping ; stems erect, 2-9 in. high, pilose with soft spread- 
ing hairs. Leaves all radical, on slender petioles 4-lin. long; 
blade about the same length, oblong or ovate-oblong, obtuse, sub- 
cordate or cuneate at the base, crenate, rather membranous, 
sparsely glandular-hairy on both surfaces or almost glabrous. 
Flowering-stem or scape 1-8-flowered ; bracts in pairs or rarely in
