We are at present acquainted with seven Polynesian species of this genus, four, discovered in Captain 
Cook’s voyages, being indigenous to the Society Islands, and three to Viti, The species [ have named 
O. Solandri differs from all the other Ophiorrhizas of this region by its peduncles being much longer than 
the leaves, its rugose leayes, and sctaceous stipules. O. Nelsoni, Seem., is a larve-leaved epecies, with 
ovate, fimbriate, and persistent stipules, and a many-flowered cyine, shorter than the leaves. QO. Tahitensis, 
Seem., has stipules, which at the base are ovate, and suddenly terminate in a long setaceous apex; O. sub- 
umbellata, Vorst.., described and figured by Forster with alternate leaves, has, in Forster's authentic speci- 
mens, opposite ones. O. Jara and O, leptantha—if indeed they be two distinet species—have setaceous 
stipules. On O. peploides I cannot find any stipules, unless some of the leaves of each whorl are regarded 
fis such as those of Galiun, ete. are. The four Tahitian species may be thus defined -—
