1. H. vulgaris L. , Sp. Pl. 4 (1753) View Cited Treatment .
Aquatic perennial with creeping rhizome from which arise erect leafy shoots (4-)30- 60(-150) cm. Leaves (0-5-)5-8(-10) cm, obovate to linear-lanceolate, (2—)6—12(—18) in a whorl. Nut 2-3 mm, ovoid, smooth. 2« = 32. Almost throughout Europe, but rare in the south-west and extreme south. All except Az BI?Co Gr Sa Si Tu.
A very plastic species. The submerged parts usually have long, linear-lanceolate, flaccid, light green leaves, while the emergent parts have short, linear, rigid, dark green leaves.
H. tetraphylla L. fil. , Suppl. 81 (1781), is often recognized as a distinct species with leaves very short, obovate and 4 in a whorl. These characters are to some extent under environmental control, and can be induced by conditions of high salinity or low temperature. The status of such variants is therefore doubtful.
