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 membranous, 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 pedicellate 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, 5-?1n. diam., white or white with purplish streaks ; pedicels 
3-2 in. long, slender, erect. Calyx deeply 5-partite; segments }in. long, 
lanceolate or linear, glandular-hairy. Corolla-tube slightly curved, villous 
within; lobes obovate, retuse. Capsule $in. long, ovoid-oblong, turgid, 
membranous.—Hook. f. Fl. Nov. Zel. 1 (1853) 197; Handb. N.Z. Fl. (1864)

NortH AND SoutH IsLtAnps: Not uncommon in damp mountainous localities from 
Moehau (Cape Colville), Mount Hikurangi, and Mount Egmont southwards to Banks 
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 originally discovered by 
Dieffenbach. 
3. O. Crosbyi Cockayne in Trans. N.Z. Inst. xlvii (1915) 113.—A slender 
more or less pubescent herb 6-10 in. high or more ; rhizome long, creeping, 
but becoming erect towards the top, internodes $-2in. long. Radical 
leaves more or less clothed with short white hairs, long-petioled ; petioles 
1-2in. long, very slender; blade #-14in. long, oblong or oblong-ovate, 
obtuse or subacute, obtusely serrate, very thin and membranous, venation 
reticulated, but not distinctly so. Flowering stem very slender; bracts: 
In opposite pairs, similar to the leaves but much smaller, sessile or nearly 
so. Flowers 3-5, about in. diam.; pedicels }-}in. long, slender. Calyx 
deeply 5-partite; lobes linear, exceeding the corolla-tube. Corolla white 
with a yellow throat; tube short. Ripe capsule not seen. 
Sout Istanp: Nelson—Hope Valley, H. J. Matthews! Otago—Dusky Sound, 
Rf. M. Laing! Southland—Lake Hauroko, J. Crosby Smith! Longwood Range, 
Cockayne! Stewart Istanp: Paterson’s Inlet, Petrie / forest near Mount Anglem, 
Cockayne. Sea-level to 3000 ft. December—January. 
I am not at all satisfied that this is anything more than a small shade form of 
O. macrophylla, of which I have several varieties closely approaching it. 
4. O. Colensoi Hook. f. Handb. N.Z. Fl. (1864) 218.—Rhizome slender, 
creeping ; stems erect, 2-9 in. high, pilose with soft spreading hairs. Leaves 
all radical, on slender petioles 4-1 in. long; blade about the same length, 
oblong or ovate-oblong, obtuse, subcordate or cuneate at the base, crenate, 
rather membranous, sparsely glandular-hairy on both surfaces or almost 
glabrous ; venation distinct on the under-surface. Flowering stem or scape 
l-8-flowered ; bracts in pairs or rarely in threes, linear-oblong, crenate. 
Flowers $in. diam., white; pedicels }-lin. long. Calyx 5-partite ; seg- 
ments linear, glandular- pubescent. Corolla-tube short, curved > lobes 
obovate, retuse. Capsule broadly oblong, turgid—Cheesem. Man. N.Z, Fl.
