The physiognomy of the vegetation with which the Reed is associated—osiers, willows, typha, scirpus, sedges, thistles, &c.—is discussed at length.
Rossmann, Julius.—Ueber die Bezeichnungen für Phanerogamen und Kryptogamen.—Oberhessisch. Gesell. Natur-und Heilkunde, Achter Bericht., pp. 23–4.
Professor Rossmann objects to the terms Phanerogamia and Cryptogamia as applied to flowering and flowerless plants, inasmuch as some of the so-called Cryptogams are, in fact, as to their reproductive processes, more Phanerogamous than any bearing flowers. He proposes to substitute Anthophyta and Sporophyta. The Professor has also a controversy with generic and specific names involving contradiction or nonsense, as in the case of Sagina apetala, Potentilla sterilis, and even Gypsophila, the species of which are not all "chalk-loving."

The lower membranous portion of the corolla-tube divides transversely, leaving a small sheathing ring around the ovary.

The Ler or Rör was a small lake about two English miles from Copenhagen, which formerly served for the supply of water to the city. In the spring of 1852 it was commenced draining—an operation which was almost completed when again visited by the author in the autumn of the same year. He was there again in 1854, and in 1857 and 1858 made repeated herborisations, and carefully collected all the native vegetation which had sprung up, amounting to 175 species, including 19 of Salix.
One of the most remarkable plants observed was the Senecio (Cineraria) paluntris, of which, in 1852, when the lake was half drained, there were only a few scattered individuals. In 1854 the whole bed of the lake was yellow with its blossoms; but in 1857 and 1858 it had so far disappeared, that Mr. Rostrup only succeeded in finding a single specimen. This recalls a similar circumstance observed in Holland in 1853, when the large portion of the lake of Haarlem, which had been drained off the previous summer, was a sheet of yellow with the blossoms of the same Senecio, which, we understand, has since nearly disappeared. Rumex maritimus, and Blitum glaucum, rubrum, which were in the greatest abundance in the drained parts of Lake Ler, in the autumn of the first year, 1852, had also almost disappeared in 1857 and 1858. The paper concludes with some speculations on the probable origin of the present vegetation.
