14 TRIANDRIA — DIGYNIA. [Narcltis. 



valved, imbricated on all sides, the lower ones smaller, empty. 

 Bristles several, iricliided, toothed. Style subulate, bifid, dilated 

 at the base. Nut crowned with the persistent, more or less 



articulated, style. — Nat. Orel. Cypeuace^, Juss Named from 



Suyyo;, a beali, and c-osa, a seed. (Very different in habit from 

 Elcocltaris, but too near in generic character.) 



9. SciKPUs. Glumes of one valve, imbricated on all sides, 

 equal, 1 or 2 of the outer ones sometimes sterile. Bristles 

 sometimes wanting. Style inarticulated, deciduous, leaving 

 only a small mucro. — Nat. Ord. CyperacRyT:, Juss. — Name, 

 according to Tlieis, from Cirs, in Celtic, which makes Cors in 

 the plural, whence chorda in Latin, and cord in English ; the 

 stems having been formerly employed for the same purposes as 

 those of Scliamis. 



10. Bi.YSMLs. Spilielets bracteated, arranged on a zigzag 

 rachis into a distichous compressed spike. Glumes oi one valve, 

 imbricated on all sides, the outermost gradually the largest, 

 empty. Bristles several or none. Fruit compressed, oval, 

 gradually tapering into the persistent style. — Nat. Ord. Cy- 

 PERACEiE, Juss. — Named from l3Xva/j!,Qg, source or spring, near 

 which the species usually grow. 



11. Eleocharis, Glumes of one valve, imbricated on all 

 sides, uniform, scarcely any empty. Bristles (4 — 12) toothed, 

 rarely none. Style 2 — 3-fid, its dilated base jointed upon the 

 germen. Nut mostly lenticular, crowned with the broad base 

 of the indurated style. — Marsh -plants. Stems simple, leafless, 

 she^tthed at the base. Spike solitary, terminal, erect, not leafy. 

 Br. — Nat. Ord. Cyperace^, Juss. — Name, £?.o;, f >.jo?, a marsh, 



and %c.;jw, to ddight, from its place of growth This genus, if 



it ought to be kept distinct from Scirpus, is better distinguished 

 by its solitary spike than by any character taken from the 

 jointed or dilated base of the style. It is again divided by 

 some Botanists ; and the genera Isolejns, Br. and Eleogiton, 

 Link, constituted. 



12. Eri6phoru3I. Glumes o^ one \n\ve, imbricated on all sides,
