198 FLORA OF NEW ZEALAND. [ Scrophularinee. 
A very handsome plant, variable in size from an inch to 2 feet, glabrous or pilose, or almost hispid with 
spreading hairs. Stems short, creeping, sending down strong, thick, fibrous roots. Radical leaves on long stout 
petioles, exceedingly variable in size and thickness on large plants; petiole 3 inches long; blade as long, ovate, 
cordate, or oblong, oblique at the cuneate base, blunt, crenate, glabrous or hairy on both sides. Scape or flowering 
stem a foot high, stout, erect, flexuose, with one or two pair of sessile, oblong, crenate cauline leaves. Inflorescence 
of one umbellate raceme of pedicellate flowers, or several (three to seven) whorls of pedicellate flowers ; umbels or 
whorls involucrate, with many linear-oblong leaves, much shorter than the pedicels, which are erect, slender, 13-2 
inches long. Sepals lanceolate, 4 inch long. Corolla white or purplish, with a curved tube, villous within, 3 inch 
long, and five obovate retuse lobes, 2 inch across. Capsules membranous, + inch long.—I have numerous speci- 
mens of this very beautiful plant, which present all varieties, from a little alpine hairy herb an inch long, with a 
single white flower 4 inch across, to a stout, erect, leafy plant, 2 feet high, with long, petioled, broad leaves $ foot 
long, and seven involucrate whorls of ten flowers in each whorl, and corollas 2 inch in diameter, of a fine pale purple 
colour. Dr. Lyall’s Chalky Bay specimens are more slender, membranous, and pilose than those from the Northern 
Island. They are not in flower.

Has. Middle Island. Dusky Bay, Zyall. 
Very nearly allied to 0. macrophylla, much resembling the largest-sized specimens of that plant, but uniformly 
much more robust and glabrous, with more coriaceous broader leaves and large capsules. Sepals 4 inch long, linear- 
oblong, blunt. Capsules very large, as long as the sepals, or nearly so. Corolla smooth inside.—My specimens 
vary from a span to a foot and a half high. 
3. Ourisia cespitosa, Hook. fil.; humilis, depressa, glaberrima, caule crasso repente ramosissimo, 
ramis brevibus prostratis foliosis, foliis subimbricatis patulis crassis coriaceisque obovato-spathulatis breve 
petiolatis recurvis obtusis obtuse 2—4-crenatis enerviis, petiolis vaginantibus glaberrimis ciliatisve, pedunculis 
brevibus crassis erectis 2-4-floris foliatis, floribus pedicellatis erectis, sepalis linearibus obtusis tubo corolle 
brevioribus, corollee intus pubescentis lobis tubo brevioribus. 
Has. Northern and Middle Islands. Summit of the Ruahine mountains, Colenso. Milford Sound, 
Lyall. 
Everywhere quite smooth. Stems 2-4 inches long, stout, creeping, much branched, very leafy. Leaves 
numerous, imbricating, patent, recurved, very thick and coriaceous, 4-2 inch long, with three to four blunt crena- 
tures. Petiole sheathing at the base, glabrous or ciliated. Pedunele stout, erect, 1-2 inches high, with one to 
three pairs of small opposite bracts or leaves, from the axils of which spring solitary pedicels. Sepals linear, blunt, 
1 inch long, shorter than the broad tube of the corolla. odes of corolla shorter than the tube, which is glabrous 
inside. 
Norn. I have a fragment of possibly a fourth species of Ourisia, gathered by Mr. Colenso near Taupo, but 
too imperfect for description, and perhaps only a state of O. macrophylia.

antherarum loculis mucronatis. Stylus apice subdilatatus. Capsula oblonga, compressa.
