1. O. peploides, A. Gray in Proceed. Amer, Acad. vol. iv.; herbacea, pumila, diffuse ramosa ; 
ramis puberulis foliosis; foliis parvis 2-G-natis vel pscudo-verticillatis spathulatis seu ovato-spathu- 
latis basi longe attenuatis glabris; flovibus subsolitariis glabris; filamentis filiformibus cum stylo ex- 
sertis—On the banks of rivers and rivulets, Ovalau, Matuku, Taviuni, and Viti Levu (Seemann! 
n. 228; M‘Gillivray! U.S. Expl Exped.! Harvey! Milne! Greeffe !). 
A very distinct-looking species; the leaves resemble those of Peplis Portula. 
2. O. leptantha, A, Gray in Proceed. Amer. Acad. vol. iv,; suffruticosa, fere glabra; foliis op- 
positis petiolatis lete viridibus oblongo- v. elongato-lanceolatis utrinque acuminatis; stipulis utrinque 
2 setaceis; cyma co-flora pubcrula; floribus plerisque secundis subsessilibus; corolla (alba) gracili 
pollicari, ore tenuissime barbato; staminibus inclusis; filamentis antherze equilongis; stylo glabro. 
—Rather common in Viti Levu, Gau, and Ovalau (Seemann! n. 229; Harvey! U.S. Expl. Exped.). 
3. O. laxa, A. Gray in Proceed. Amer. Acad. yol, iv.; suffruticosa; ramis junioribus szpe fer- 
rugineo-puberulis; foltis oppositis longe petiolatis oblongis v. subovatis acuminatis; stipulis utrin- 
que 2 setaceis; cymis pauci-plurifloris laxis; floribus pedicellatis; corolla semmpollicari; cet. fere 
preecedentis, sed ramosior laxior.—-With the preceding, generally growing on the outskirts of woods 
(Seemann! n, 227; Milne! U.S. Expl. Exped.). 
_ A. Gray thinks these two last species confluent, and future investigation will probably confirm that 
opinion. | :
