‘the base. Ovaries 5, several of them usually becoming abortive. Styles 5. 
Capsules glabrous, pod-shaped, usually solitary from abortion. Seed soli- 
tary, usually (always?) with a complete or incomplete arillus : albumen none. 
To this belongs Omphalobium, S Cnestoidea of De Candolle, Cnestis Á—— 
Roxb., C. emarginata, florida, and memosoides of Jack, Connarus Roxburghii, Hook. 
and Arn. (in Bot. Beech. Voy. p. 179), and Conn. microphyllus, Hook. and Arn. 
(l c.) It was at one time — that C. Rorburghti, H. & A., had been found 
in the Peninsula; but although extremely similar to the Chinese plant, Dr Wight's - 
~ peta have now been ascertained to be Conn. monocarpus.—Robergia hirsuta of 
oxburgh appears to be a true Cnestis.

a narrow blunt acumination, thin-coriaceous, shining, veins prominent: pa- 
nicles narrow, axillary and terminal, few-flowered: sepals ovate, glabrous: 
ovaries glabrous : capsule solitary.—Wight ! cat. n. 539.— Connarus santaloi-

Our specimens are from Rottler's herbarium, from Columbo in Ceylon, and 
were named by Vahl to the missionaries Conn. santaloides, so that we are en- 
abled to determine Vahl's mistake when he says “ stylus unicus." We have 
not seen the fruit, but according to Vahl it is solitary. 
ORDER XLVI.—ZYGOPHYLLEZJE. R Brown. 
Flowers bisexual, regular. Calyx 4-5-divided. Petals unguiculate, 
alternate with the sepals : estivation usually convolute. Stamens twice 
as many as the petals, hypogynous : filaments distinct, dilated at the 
base, and usually arising each from the back of a scale: anthers 2- 
celled, opening longitudinally. Ovarium simple, more or less 4—5-fur- 
rowed, 4—5-celled: ovules in pairs or more, pendulous, or rarely erect: 
style simple, often 4—5-furrowed : stigma simple, or 4—5-lobed. Fruit 
capsular, or rarely fleshy, with 4—5-angles or wings, 4—5-valved and lo- 
culicidal, or indehiscent: endocarp and sarcocarp combined. Seeds 
usually fewer than the ovules. Albumen between fleshy and horny, 
rarely 0. Embryo green: radicle superior : cotyledons foliaceous.— 
Leaves opposite, stipuled, not dotted, rarely simple.

I. TRIBULUS. Linn.; Lam. ill. t. 346 3; Gaertn. fr. t. 69. 
Calyx deeply 5-partite, usually permanent. Petals 5, longer than the ca- 
lyx. Stamens 10, filaments naked, the five opposite to the sepals with à 
gland externally at the base. Ovary hairy, usually girt at the base by a 10- 
toothed urceolus or 5 scales opposite to the sepals, 5-celled: ovules 3-4 m 
each cell, superposed, pendulous. Style short or scarcely any. Stigma 
large, broader than the style, 5-ribbed. Fruit 5-coccous ; cocci remaining 
long connected together, at length separating, indehiscent, externally tuber- 
culate or prickly, internally divided obliquely by transverse septa into 
superposed 1-seeded cells. Seeds without albumen: embryo straight.— 
Diffuse, trailing, herbaceous plants. Leaves opposite, 2-stipuled, abruptly ; 4
