PHANEBOGAMIA. 109 



The physiognomy of the vegetation with which the Reed is asso- 

 ciated — osiers, willows, typlta, scirpus, sedges, tlristlcs, &c. — is dis- 

 cussed at length.

 Kryptogamen. — Oberhessisch. Gesell. jNatur-und Heilkunde, Achter

Professor llossmann objects to the terms Phanerogamia and Cryp- 

 togamia as applied to flowering and flowerless plants, inasmuch 

 as some of the so-called Cryptogams are, in fact, as to their repro- 

 ductive processes, more Phanerogamous o than any bearing flowers. 

 He proposes to substitute Anthophyta and Sporophyta. The Pro- 

 fessor has also a controversy with generic and specific names in- 

 volving contradiction or nonsense, as in the case of Sagina apetala, 

 Potentilla sterilis, and even Gypsopliila, the species of which are not 

 all " chalk-loving."

The lower membranous portion of the corolla-tube divides trans- 

 versely, leaving a small sheathing ring around the ovary.

The Ler or Bor 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 opera- 

 tion 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 col- 

 lected 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 ob- 

 served 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 glancum, andrubriuu, 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 pre- 

 sent vegetation.
