430 BOTANICAL GEOGRAPHY. 



the Lichens arid some additions (V. d. Hoeven, Tyd- 

 schrift, vol. xii, pp. 1-22), e. g. in the coast districts of the 

 Netherlands : Cerastium tetrandrum, Trifolium subterra- 

 neum, and Centaur ea nigra, are found common, also Salix 

 holosericea, Car ex trinervis (C. rigida Fl. Leyderis), and 

 Zygodon viridissimus. The contributions to the Crypto- 

 garnic Flora of the Netherlands, by Dozy and Molkenboer, 

 have been continued (ibid. pp. 257-88) : on the Fungi, 

 containing among them some new species which are 

 illustrated by figures. General works on the Flora of 

 Germany : Reichenbach's Icones, vol. vii, Dec. 5-1 0, with 

 the Naiadeae, Alismacese, Hydrocharidaceae, Nymphaeaceae, 

 and a supplement to the Grasses ; Sturm's Flora, sect. 1, 

 parts 89, 90, principally containing species of Viola and 

 Labiatae ; V. Schlechtendal and Schenk's illustrated work, 

 vol. vi; Lincke's Publication, parts 50-9; Koch's synopsis, 

 ed. 2, fasc. 3 (Lips. 1845), containing the Ferns, with 

 appendices and the Index : an abridgment of this work 

 appeared as a pirated edition under the false name of 

 Herold ; Nees v. Esenbeck's Genera Plantarum Florae 

 Germanicae, continued by Putterlick and Endlicher, fasc. 

 24 (Bonn, 1845, 8vo). Special systematic works on the 

 Flora of Germany : Sauter's new Contributions to the 

 Flora of Germany (Ratisbon Flora, 1845, pp. 129-32) : 

 unimportant notices, with the diagnosis of a new Riccia ; 

 Perktold, the Hypna of Tyrol (Neue Zeitschr. des Ferdi- 

 nandeums, Bd. 11) ; Rabenhorst's Cryptogamic Flora of 

 Germany (see the preceding Ann. Rep.) vol. ii. pt. 1, 

 containing the Lichens ; Roemer, the Algae of Germany 

 (Hanover, 1845, 4 to; with 11 plates), confined to the fresh- 

 water Algae, principally the forms found by the author 

 on the upper Hartz, and imperfectly illustrated by bad 

 lithographic drawings ; arranged according to Kiitzing's 

 system, but paying no attention to the history of develop- 

 ment ; Kiitzing's Phycologia Germanica (Nordhausen, 

 1845, Svo). It includes the entire flora, and only appeared 

 a few weeks after the preceding work, Roemer's materials 

 having been made use of ; yet it is carried out perfectly
