Although I have many and good specimens of the New Zealand Ohves, they are not sufficient in a genus so
remarkable for the protean forms of its leaves to pronounce decidedly upon. I have therefore, in separating this
from 0. Cunningliamii, rehed more upon the nervation than on any character of form or dimensions, and have
united under the varieties a and ,3 of this, plants differing only in the size and breadth of the leaf.—0. lanceolata
is a smaller tree than O. Cunningliamii, 20-30 feet high, with smaller, narrower, less coriaceous, sharper leaves,
varying from less than 2 inches long in var. 0 to 3 | in var. a, and proportionally in breadth, from linear to ovate-
lanceolate. The veins in dried specimens are prominent on both surfaces, and are reticulated towards the margin,
with very broad open spaces, whereas in 0. Cunninghamii they are fewer, spread more from the costa, do not branch,
and present sunk lines on the upper surface. The flowers and fruit are much the same in both, but the racemes
more slender, fewer-flowered, less hairy, in 0. lanceolata. Berry crimson.

tricts, Cunningham, Colenso.
A large bushy-headed tree, 40-50 feet high. Branchlets pubescent. Agaves very narrow, linear, coriaceous,
2-3 inches long ou old trees, 6 and upwards on young ones, acuminate or blunt, seldom more than i inch broad,
very coriaceous, sliimng, veinless, or with a few parallel reticulated veins. Inflorescence as in the former species,
but smaller in the same proportion in all parts as the foliage is smaller. Berries 4 inch long, linear-oblong. I have
given on Plate XLVI., at fig. B, a pair of leaves of one of Mr. Cunningham’s specimens of Metrosideros salicifolia,
which I thought at one time belonged to another Olea, bnt wliich I now suspect are Mida salicifolia, Cunn.__

N a t . O r d . LIV. LOGANIACEÆ.
Gen. I. LOGANIA, Br.
Calyx 5-partitus. Corolla subcampanulata, fauce villosa v. pilosa, lobis æstivatione imbricatis. Stamina
5, tubo corollæ inserta. Stylus I, persistens. Ovarmm 2-loculare. Capsula 2-partibilis. Semina numerosa,
peltata ; placenta suturæ ventrali adnata.
The only New Zealand species is a small, alpine, woody, rigid, branching, prostrate shrub, with numerous
small white flowers, turning black when dry, and much resembling an alpine Coprosma. Stems 3-6 inches long,
much branched ; branches short, rigid, pubescent. leaves 4 inch long, crowded, opposite, the bases of each pair
united by two small blunt stipules, very coriaceous, elliptical, ovate or spathulate, blunt, nerveless, quite glabrous,
entire and shinmg. Mowers 1 line long, two to three together, on axillary, stout, pubescent pedicels, wliich arc
shorter than the leaves, and furnished with opposite, subulate connate bracts. Calyx of five oblong, blunt, ciliated
sepals. Corolla with a short tube and five veined, rounded, spreading, imbricated lobes, villous at the mouth.
Stamens five ; filaments slender ; anthers deeply two-lobed from the base upwards. Ovary very small, low, depressed
; style erect, with a short club-shaped stigma.—This genus is frequent in AustraUa, but not found in Tasmania,
where are numerous species of the allied genus Mitrasacme, of which it is somewhat remarkable that none
are found in New Zealand. (Named in honour of James Logan, a botanical author.)
1. Logania depressa, Hook. fil. ; fruticulus rigidus, decumbens, lignosus, ramosissimus, ramis crassis,
ramulis pubescentibus, foliis parvis elliptico-ovatis spathulatisve coriaceis nitidis, pedunculis axillaribus
2-3-fioris bracteatis.
H a b . Northern Island. Euahine Mountains, Colenso.
I have seen no fruit of this plant, nor can I determine the nature of the ovarium. I had long overlooked it in
Mr. Colenso’s collection, assuming it to be a prostrate woody Coprosma, like C. cuneata, and I am indebted to Mr.
Bentham for determining it to be a Logania, as far as can be judged without the fruit. It may prove to be a species
of Geniostoma.
Gen. II . GENIOSTOMA, Forst.
Calyx 5-fidus. Corolla tubulosa v. subcampanulata, fauce barbata, lobis 5. Stamina 5, fauce corollæ
inserta ; filamentis brevibus. Ovarium 2-loculare. Capmla 2-locularis ; valvis 2, iutegris, marginibus
iiitroflexis placentiferis cohærentibus columnam liberam semi-inferam post dehiscentiam valvarum efficienti-
bus. Semina plurima.
This genus agrees in all respects but the structure of the capsule with Logania. The valves of the capsule are
entire (not bifid), and their opposite margins are iuflexed, meet in the axis, and are united by the placentæ, forming
a central seed-bearing column, from which the valves when ripe faU away.—The genus is a small and insular one, a
few species inhabiting the Pacific Islands and the Mauritius. (Name from yev^iov, a beard, and trrofia, a mouth ;
from the villous corolla.)

A perfectly smooth, branching, leafy, evergreen bush or small tree. Branches slender. Leaves elliptical-ovate,
shortly petiolate, acuminate, 2-3 inches long. Flowers white, small, on axillary, simple, or branched peduncles,
which are slender, bracteate, about as long as the petioles when in flower ; bracteolæ small, subulate. Calyx lobes
acute. Corolla villous at the mouth ; lobes reflexed. Stigma two-lobed. Capsule of two ovate, sharp, boat-shaped
valves.
