Gentianee. | FLORA OF NEW ZEALAND. 177 
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, de- 
pressed; style erect, with a short club-shaped s/igma.— This genus is frequent in Australia, but not found in Tas- 
mania, 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.)

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.

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 inflexed, meet in the axis, and are united by the placent, forming 
a central seed-bearing column, from which the valves when ripe fall away.—The genus is a small and insular one, a 
few species inhabiting the Pacific Islands and the Mauritius. (Name from yevewov, a beard, and oropa, 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; bracteole small, subulate. Calyz lobes

valves.
