1. O. peploides, A. Gray in Proceed. Amer. Acad. vol. iv. ; herbacea, pumila, diffuse ramosa ; 
ramis puberulis foliosis; foliis parvis 2-6-natis vel pseudo-verticillatis spathulatis seu ovato-spathu- 
latis basi longe attenuatis glabris; floribus 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! Greffe !). 
= 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 læte viridibus oblongo- v. elongato-lanceolatis utrinque acuminatis ; stipulis utrinque 
2 setaceist cyma oo-flora puberula; floribus plerisque secundis subsessilibus ; corolla (alba) gracili 
pollicari, ore tenuissime barbato; staminibus inclusis; filamentis antherz :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. vol. iv.; suffruticosa ; ramis junioribus sepe fer- 
rugineo-puberulis; foliis oppositis longe petiolatis oblongis v. subovatis acuminatis; stipulis utrin- 
que 2 setaceis; cymis pauci-plurifloris laxis; floribus pedicellatis; corolla semipollieari; cat. fere 
procedentis, 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. l
