836 SCROPHULARIACEAE. [Ourisia. 
I am now convinced that this species should be limited to the plant originally 
discovered by Colenso near the base of Ruapehu and on the Ruahine Mountains. The 
South Island specimens attributed to it differ in many respects, and are best referred to 
small states of D. macrophylla or to O. Crosbyt. 
5. O. sessilifolia Hook. f. Handb. N.Z. Fl. (1864) 218.—Rhizome stout 
or slender, creeping and rooting, branched, glandular-hairy above. Leaves 
all radical, spreading and appressed to the surface of the ground, 1-2 in. 
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. Pedunele stout, 2-6 in. high, 
2-8-flowered, most densely villous, as are the bracts, pedicels, and calyces. 
Bracts obovate or oblong, crenate; pedicels short, stout. Flowers large, 
3in. 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—

Soutn TsLanp: Marlborough—Kaikoura Mountains, Buchanan! Nelson—Mount 
Buckland, W. Townson! Canterbury, Westland, and Otago—Net uncommon on the 
higher mountains of the dividing-range, and particularly abundant in the Mount Cook 
district, and extending to the Takitimu Mountains. Srmwart Isnanp ; Upper slopes

A handsome plant. Its habit is peculiar, the lower portion of the stem being 
creeping and rooting, the leaves being practically bifarious and closely appressed to 
the surface of the ground. The stout peduncle is often 6 in. high, and bears numerous 
large white flowers, which shade into dark-violet towards the base. When in full 
flower it is thus a charming and attractive plant. ' 
6. 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, #-l}in. long, ovate or ovate- 
spathulate, obtuse, suddenly narrowed into rather long sheathing petioles, 
erenate, bright-green above, often purplish below, coriaceous, glabrous 
or the margins of the petioles ciliate. Peduncles stout, erect, purplish, 
3-6in. high, 3-6-flowered, glabrous or nearly so. Bracts rather large, 
narrow obovate-spathulate, crenate, margins sometimes ciliate towards the 
base; pedicels slender, 1-I4in. 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 cap- 
sules not seen.—Cheesem. Man. N.Z. Fl. (1906) 550. —

Allied to O. caespitosa, but well distinguished by the larger size, much larger 
ovate-spathulate long-petioled leaves, and larger flowers. 
7. O. eaespitosa Hook. f. Fl. Nov. Zel. i (1853) 198.—Forming broad 
matted patches. Stems often much branched, 2-6 in. long or more, creeping 
and rooting, stout or rather slender, leafy, glabrous or sparingly pilose or 
tomentose ; branches short, ascending. Leaves close-set, spreading and 
recurved, usually distichous, $-4in. long, obovate - spathulate, obtuse, 
narrowed into a short broad sheathing petiole or almost sessile, coriaceous
