terminal, seen with old fruit only. Calyx about as large as the leaves ; tube

2. GENIOSTOMA, Foist. 
Characters of Logania , but the valves of the capsule not 2-fid nor 2-partite, 
the aestivation of the corolla-lobes contorted, and the calyx less deeply divided. 
A considerable genus of Madagascar and Bourbon, the Asiatic and Polynesian islands, 
not found in continental Africa, nor in Australia. 
1. G. ligustrifolmm, A. Cunn. ; — FI. N. Z. i. 177. A perfectly gla- 
brous shrub or small tree; branches slender. Leaves lf-3 in. long, ovate- 
oblong, acuminate, membranous. Flowers in short, axillary and lateral 
corymbs, i in. diam., white; peduncles and pedicels bracteolate. Corolla- 
tube very short, lobes reflexed. Ovary globose, with a veiy short style and 
large 2-lobed stigma. Capsules on slender divaricating pedicels, globose, 
mucronate, ^ in. diam., valves separating from the placentiferous axis.— Hook.

Northern Island : not uncommon in woods, etc., Banks and Solander, etc. 
Order XLIX. GENTIANE^. 
Herbs, usually glabrous and bitter. Leaves opposite, exstipulate, quite 
entire. Flowers solitary or cymose, often handsome.— Calyx 4- or 5-lobed. 
Corolla 4- or 5-cleft or lobed, contorted in bud, persistent. Stamens 5, in- 
serted on the corolla. Ovary 1-celled, with 2 parietal placentas often pro- 
jecting into the cavity, and dividing it into 2-4 cells ; styles 1 or 2, stigma 
2-lobed or 2-capitate; ovules numerous. Capsule (rarely a berry) usually 
membranous, elongate, septicidally 2-valved. Seeds small ; albumen fleshy. 
A large tropical and temperate Order, especially abounding in mountainous regions. 
Flowers large, white or yellowish or purplish. Style 1. Stigma 2-lobed . 1. Gentiana. 
Flowers small, yellow. Ovary with 2 styles 2. Sebvea. 
1. GENTIANA, Linn. 
Erect or ascending, simple or branched herbs, with conspicuous flowers. — 
Calyx 4- or 5-cleft. Corolla 4- or 5-cleft, campanulate or rotate. Anthers not 
twisted, turning back, and so becoming extrorse. Ovary linear; style 1, 
stigma bifid. Capsule septicidal, elongated, membranous. 
A large mountain genus, found in all parts of the world. The species are most variable, 
and the New Zealand ones especially so, insomuch that in framing characters for the species 
I have had to take prevalent forms and to disregard intermediate ones, which occur in 
abundance between all. Some Chili species are too close to the New Zealand, but I hesitate 
to unite them, without better materials. 
Root annual (sometimes perennial in 3). 
Stems very slender, 1- or few-tiowered. Stem leaves few. Calyx- 
lobes subulate
