broadly-ovate, flat on the inner side, keeled on the outer, or 

 triangular with three flat sides, dark-brown and polished, 

 one or two of the bristles winged or dilated at the base. 

 Stigmas often 2 only. The spikelets more elongated than in 

 S. glaucus. 



18. Scirpus glaucus. — Anglesea, July 16, 1826. — Seed con- 

 siderably smaller than in S. lacustris, and more tapering 

 above, elliptical, though slightly thickened above, visibly 

 compressed, flat on the inner side, convex, but not keeled 

 externally, slightly beaked, light-brown, not shining. I have 

 not seen more than 5 rough bristles at the base of the seed : — 

 doubtful if a distinct species. 



19. Scirpus setaceus. — Anglesea, July 8, 1828. — Stems 

 tufted, repeatedly branched or subdivided ; leaves channelled 

 and keeled, hollow, sheathing at the base. Seed nearly 

 round, scarcely triangular, not furrowed, reddish-brown, 

 granulated, covered with a closely adhering skin. 



20. Scirpus marititnus. — Anglesea, 1826. — 4 rough bristles 

 at the base of the flower, 3 of them at the exterior base of 

 the much broader filaments. 



21. Eleocharis palustris. — Anglesea, July, 1828. — Root 

 creeping, black and shining, as well as the external sheaths of 

 the stem. Bristles, in the flower, only 4, longer than the 

 ripe seed, flattened, dilated at the base, and bi'oader than 

 the filaments. Receptacle elongated below the insertion of 

 the filaments, so that the flower appears to be not quite 

 sessile, as it is in E. multicaidis. Germen shorter and broader 

 than in the allied species, and the style also shorter. 



The section of the stem is different from that of E. multi- 

 caulis, without any central pith, but with lax'ge membranous 

 tubes, surrounded by smaller ones. 



22. Eleocharis midticaulis. — Anglesea, July, 1828. — Root 

 not creeping. Sheaths of the stem brown, not shining : the 

 stems are always inclined, and frequently bent, sometimes 

 almost prostrate. B?'istles 6, shorter and narrower than in 

 the other species, the base not dilated ; they are shorter than 

 the ripe seed : the receptacle elongated above the insertion of
