threes, linear-oblong, crenate. Flowers 4in. diam., white; pedi- 
cels +-lin. long. Calyx 5-partite; segments linear, glandular- 
pubescent. Corolla-tube short, curved; lobes obovate, retuse. 
Capsule broadly oblong, turgid. 
NortH AnD Sout Istanps: Mountainous districts from Lake Taupo and 
the Ruahine Mountains southwards. 1500-3500 ft. December-January. 
Probably only a reduced state of O. macrophylla. 
4. O. sessilifolia, Hook. f. Handb. N.Z. Fl. 218.—Rhizome 
stout or slender, creeping and rooting, branched, glandular-hairy 
above. Leaves all radical, spreading and appressed to the surface 
of the ground, 1-2in. long, broadly ovate- or obovate-spathulate, 
obtuse, suddenly narrowed into broad short petioles, crenate, 
scarcely coriaceous, pale-green, upper surface and margins densely 
villous with glandular hairs, under-surface not so thickly clothed 
but rarely glabrate. Peduncle stout, 2-6in. high, 2-8-flowered, 
most densely villous, as are the bracts, pedicels, and calyces. 
Bracts obovate or oblong, crenate ; pedicels short, stout. Flowers 
large, $in. diam., white shading into purple at the base. Calyx 
4in. long, 5-partite; segments linear-oblong, obtuse. Corolla-tube 
broad; lobes large, rounded, retuse at the tip. Capsule ovate- 
oblong, not seen quite ripe. 
Sout Isnanp: Marlborough—Kaikoura Mountains, Buchanan! Nelson 
—Mount Buckland, W. Townson! Canterbury, Westland, and Otago—Not un- 
common on the higher mountains of the dividing-range. Srmwart Isnanp: 
Summit of Mount Anglem, Kirk ! 3500-6500 ft. December—February. 
This can hardly be described as erect, the leafy part of the stem being some- 
times elongated and creeping. There seems to be two forms—one large and 
stout, very densely villous and with large flowers; the other smaller, with 
darker green leaves which are not so hairy, and with fewer smaller flowers. 
5. O. Cockayniana, Petrie in Trans. N.Z. Inst. xxix. (1897) 
426.—Forming large matted patches. Stems 3-6in. long or more, 
branched, rather stout, creeping and rooting, glabrous or nearly so. 
Leaves in close-set opposite pairs, spreading and recurved, 3-14 in. 
long, ovate or ovate-spathulate, obtuse, suddenly narrowed into 
rather long sheathing petioles, crenate, bright-green above, often 
purplish below, coriaceous, glabrous or the margins of the petioles 
ciliate. Peduncles stout, erect, purplish, 3-6 in. high, 3-6-flowered, 
glabrous or nearly so.  lBracts rather large, narrow obovate- 
spathulate, crenate, margins sometimes ciliate towards the base; 
pedicels slender, 1-14in. long. Flowers large, #-1 in. diam., white. 
Calyx 4in. long, 5-partite ; segments oblong, obtuse. Corolla-tube 
broad, rather longer than the calyx ; lobes broadly oblong, retuse. 
Ripe capsules not seen.
