LIN. SVST. Tetrandria, 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 with a 

 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 suffriiticose 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 Hedyotis, 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, }-fionereil, usually solitary, rarely by 

 twos or threes. 



1 O. BRACHY'PODA (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. Q. F. Native of Java, 

 Philippine Islands, and Nipaul. Hedyotis herbacea, var. a. 

 Blum, bijdr. p. 970. H. radicans, Bartl. in herb. Hsenke. 

 Allied to O. herbacea but distinct, and it is probably the same as 

 0, ramoslssima or O. diffusa.

 toothed ; fruit almost solitary, axillary, sessile. I/ . F. Native 

 country unknown. Hedyotis ramosissima, Spreng. pug. 2.

 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. Q. F. Native of Senegal, in sandy places at \Valo, 

 where it was collected by Perrottet and Leprieur. Flowers 

 white. Perhaps only a luxuriant variety of 0. riparia.

 ish, tetragonal, smoothish ; leaves linear, acute, rather scabrous ; 

 pedicels axillary, 1-flowered, twin, 3 times shorter than the 

 leaves; corolla tubular, about the length of the calyx. O. 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.

 pedicels numerous, 1 -flowered, shorter than the leaves ; lobes 

 of calyx ciliated ; throat of corolla villous. . F. Native of

 branched ; stem tetragonal ; leaves linear, acute ; stipulas cu- 

 pulate, furnished with many bristles ; pedicels axillary, twin, 

 1-flowered, about the length of the leaves : but the uppermost 

 ones are longer than them ; capsule globose ; teeth of calyx

7 O. I.ANCIFO'LIA (D. C. 1. c.) stem simple, weak, somewhat 

 dichotomous, creeping, glabrous ; leaves linear-lanceolate, gla-

 leaves linear or linear-lanceolate ; stipules of many bristles ; 

 pedicels axillary, 1-flowered, solitary or twin, shorter than the

 O. tenuifolia, Burm. fl. ind. 38. t. 14. f. 1. is probably distinct 

 from this but is not sufficiently known. Flowers white.
