ZOOLOGY AND BOTANY, MICROSCOPY. ETC. 569 



simplified account of the moss-families comprised between Tortulacese 

 and Leskeacea?. 



Hepatics of Middle Europe.* — K. Muller continues his general 

 treatment of the hepatics in Rabenhorst's " Kryptogamenflora von 

 Deutschland," finishing the account of the reproductive organs, and 

 passing on to the sporophyte, which he discusses under the heads : 

 development of the embryo ; stalk ; capsule ; spores and their develop- 

 ment ; elaters. Vegetative reproduction includes sections in which 

 gemma?, adventive shoots, and tubers are treated. The biology of the 

 hepatics comprises questions of symbiosis and adaptability to dry or wet 

 environment. Finally, hints to the collector are supplied. 



Mosses of Baden.f — T. Herzog brings to an end his bryogeo- 

 graphical sketch of the moss-flora of Baden. He discusses the cha- 

 racters of the moss-floras of the Franconian Jura, the Bodensee 

 region, the Rhine-plain, the Kaiserstuhl, the Odenwald, and concludes 

 with a long table exhibiting the horizontal distribution of the species in 

 Baden, which for the purpose is here divided into eleven districts. 



Mosses of Zurich.} — P. Culmann publishes a supplement to the 

 catalogue of mosses issued a few years ago by himself and J. Weber. It 

 consists of a list of hepatics of the canton of Zurich, including parts of 

 the valleys of the Rhine, the Toss, the Grlatt, the Limmat, the Sihl, and 

 the Reuss. Ninety-seven species are recorded. 



Moss-flora of Tyrol.§ — A. Holler published as the last paper before 

 his death, a list of the mosses from Tyrol and the neighbouring Bavarian 

 Alps, represented in his large herbarium. Records from Eastern Allgau 

 are also included. The list includes important finds made by Sendtner, 

 Molendo, Progel, Berggren, Sauter, Bamberger, Arnold, and others. 

 The height above sea-level is always indicated. Hypnum pygmmum 

 Molendo is the true H. condensation Schimper according to the original 

 plant of Sendtner in Herb. Schimper ; forms of H. revolutum and of 

 H. Vancheri were distributed by Molendo under that name. H. conden- 

 sation Schimp. belongs to H. revolutum Mitten, not to H. Bambergeri 

 Schimp. 



New Austrian Mosses. || — V. Schiffner and J. Baumgartner describe 

 two new mosses from the Wachau, or valley of the Danube, in Lower 

 Austria, to wit, Cinclidotus danubicus and Didymodon austriacus. The 

 latter is most closely related to D. cordatus and D. rigididus. Cincli- 

 dotus danubicus is an aquatic species closely related to 0. riparius, with 

 which it often grows intermixed. The authors compare the characters of 

 the two species in parallel columns. Both the new species are widely 

 distributed in the district, and, according to the authors, are distinct and 

 good species.
