Although I have many and good specimens of the New Zealand Ohves, they are not sufficient iu a genus so
remarkable for the protean forms of its leaves to pronounce decidedly upon. I have therefore, in separating this
from 0. Cunninghamii, relied more upon the nervation than on any character of form or dimensions, and have
united under the varieties a and 8 of this, plants differing only in the size and breadth of the leaf.— 0 . lanceolata
is a smaUer tree than 0 . Cunninghamii, 30-30 feet high, with smaUer, narrower, less coriaceous, sharper leaves,
varying from less than 3 inches long in var. ^ to 34 in var. a, and proportionaUy in breadth, from Unear to ovate-
lanceolate. The veins in dried specimens are prominent on both surfaces, aud 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.

A large bushy-headed tree, 4 0 -5 0 feet high. Branchlets pubescent. Zeoyes very narrow, Hnear, coriaceous,
2 -3 inches long on old trees, 6 and upwards on young ones, acummate or blunt, seldom more than 4 inch broad,
very coriaceous, sliining, veinless, or with a few parallel reticulated veins. Injhrescence as in the former species,
but smaUer in the same proportion in aU parts as the fohage is smaUer. Berries 4 inch long, Hnear-oblong. I have
given on Plate XLVI., at fig. B, a pair of leaves of one of Mi*. Cunningham’s specimens of Metrosideros salicifolia,
which I thought at one time belonged to another Olea, but which I now suspect are Mida salicifolia, Cunn.__

The only New Zealand species is a smaU, alpine, woody, rigid, branching, prostrate shrub, with numerous
smaU white flowers, turning black when dry, and much resembling an alpine Coprosma. Slems 3 -6 inches long,
much branched ; branches short, rigid, pubescent. Leaves 4 inch long, crowded, opposite, the bases of each pair
united by two smaU blunt stipules, very coriaceous, eUiptical, ovate or spathulate, blunt, nerveless, quite glabrous,
entire and shining. Plowers 1 Une long, two to three together, on axiUary, stout, pubescent pedicels, which are
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, vUlous at the mouth.
Stamens five ; filaments slender ; anthers deeply two-lobed from the base upwards. Ovary very smaU, low, depressed
; style erect, with a short club-shaped stigma.— This genus is frequent in Australia, but not found in Tasmania,
where are numerous species of the allied genus Mitrasame, of which it is somewhat remarkable that none
are found in New Zealand. (Named in honour of James Logan, a botanical author.)

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, Hke Q. cuneata, and I am indebted to Mr.
Bentham for determining it to be a Logania, as far as can be judged without the fruit. I t may prove to be a species
of Geniostoma.

This genus agrees in all respects b u t 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, fi*om which the valves when ripe fall away.—The genus is a small and insular one, a
few species inhabiting tbe Pacific Islands and the Mauritius. (Name from y^vuov, a heard, and crro/ia, a mouth ;
from the villous corolla.)

A perfectly smooth, branching, leafy, evergreen bush or smaU tree. Branches slender. Leaves elHptical-ovate,
shortly petiolate, acuminate, 2-3 inches long. Plowers 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
