Lin. syst. Tetrdndria, Monogynia. Calyx with a sub- 
globose tube, and 4 sub-approximate teeth, which remain on the 
fruit and are separated by very wide recesses. Corolla witha 
short tube, a 4-cleft limb, and a villous or glabrous throat. 
Stamens a little exserted ; anthers ovate or orbicular. Stigma un- 
divided or bifid. Capsule almost globose, crowned by the small 
distant teeth of the calyx, 2-celled, dehiscing at top by a locu- 
lacidal chink. Seed small, innumerable, fixed to sub-globose 
placentas, and as if they were half immersed in them.—Small, 
herbaceous, or suffruticose plants, with the habit of chickweed. 
Leaves opposite, with the stipulas adhering to both sides of the 
petioles. Peduncles axillary and terminal, bearing 1-2 or 
many flowers, usually elongated and slender. Flowers usually 
white. This genus hardly differs from Hedyodtis, except in the 
teeth of calyx being separated by wide recesses on the fruit 
instead of narrow ones, which character we think would scarcely 
constitute a sectional distinction. The species, however, have 
a different habit, and are more readily distinguished by it, than 
by any other character. 
* Pedicels axillary, \-flomered, usually soliiary, rarely by 
twos or threes. 
1 O. sracny’popa (D. C. prod. 4. p. 424.) plant glabrous 
and decumbent ; leaves linear ; stipulas furnished with 2 bristles 
on both sides; pedicels axillary, 1-flowered, shorter than the 
flowers, solitary or twin; corolla tubular; anthers exserted to 
the length of the lobes of the corolla. ©. F. Native of Java,

toothed ; fruit almost solitary, axillary, sessile. Y.-F. Native

3 O. sasurosa (D.C. prod. 4. p. 424.) an herbaceous, tufted, 
diffuse, much-branched plant, which is roughish from short 
scattered hairs in every part; leaves linear, acute ; stipulas 
membranous, furnished with many bristles; pedicels 2-3 toge- 
ther, axillary, 1-flowered, much shorter than the leaves, deflexed 
in the fructiferous state; corolla length of the lobes of the 
calyx. ©. F. Native of Senegal, in sandy places at Walo, 
where it was collected by Perrottet and Leprieur. Flowers 
white. Perhaps only a luxuriant variety of O. riparia.

leaves ; corolla tubular, about the length of the calyx. ©. F. 
Native of Senegal, in humid sandy places, on the banks of the 
river, where it was collected by Perrottet and Leprieur. Very 
nearly allied to O. scdbrida, but is easily distinguished from it 
in the pedicels being much shorter, and the lobes of the calyx 
being longer.
