these species in France. He adds two notes treating of the resistance 

 of these plants to extermination by drought, and of the dependence of 

 some of the species upon the presence of man, some practically occurring 

 only in cultivated fields, others lying dormant until hedges are trimmed 

 back, and then gradually becoming stifled again, others abounding along 

 new railway cuttings. 



Swiss Muscinese.* — P. Culmann publishes a list of 25 hepatics and 

 71 mosses gathered by him in Switzerland, adding special notes on the 

 probable identity of Webera commutata with W. gracilis, and Brachy- 

 thecium densum with Amblystegium compactum, and on the difference 

 between Hypnum dilatatum and H. alpinum, as shown in their peri- 

 chastial leaves. He also states that the Norwegian moss, No. 826 of 

 Husnot's Musci Galliae, published under the name Webera lutescens, is 

 not that species, but Mniobryum vexans. 



Muscineae of the Dolomites. f — F. Kern gives a list of 139 mosses 

 and 17 hepatics gathered by him in the Dolomites in 1896, 1899, and 

 1908. He remarks upon the preference shown by the older bryologists 

 for the Hohen Tauern range, and the neglect manifested as a rule for 

 the Dolomites. He mentions certain bryologists who did visit the 

 Dolomites, and some of the more remarkable species which they dis- 

 covered. Although some of the Dolomites are composed of magnesian 

 limestone and others of limestone, the author can detect no difference in 

 the nature of their respective moss-floras. The constant weathering of 

 the surface makes these mountains unfavourable for the growth of 

 mosses ; and where they do occur luxuriantly on rocks in the forests, 

 they are but common calcareous species of the plain. All silicicolous 

 species, as well as Sphagnum, Andrecea, and cleistocarpous mosses, are 

 unknown there. But as regards the cleistocarps, their occurrence in the 

 early spring, before the German bryologists reach the Dolomites, may 

 account for their apoarent absence. Hypnum palustre is the only 

 representative - of the Limnobium group. The hepatics are very scarce. 

 Many species of mosses which otherwise occur only in the plains are 

 found at high elevations on the limestone of the Dolomites. 



German Mosses. — 0. Jaap and R. Timm X have submitted the 

 neighbourhood of Hamburg to a fresh search for Muscinese, and record 

 450 species. They have re-discovered all the hepatics formerly found by 

 Gottsche, except Blyttia Lyellii, and have added others. The old moss 

 records of Hiibener and Sonder are not to be trusted, as many of them 

 have never been confirmed. L. Loeske § publishes a further series of 

 notes on the bryology of the Harz mountains. He corrects a few 

 former determinations. He submits the species of Philonotis to a 

 critical revision. Lophozia confertifolia Schiffn. is new for Germany ; 

 and five mosses and one hepatic are new for the Harz mountains. 



Austro-Hungarian Mosses. — I. Gyorffy || records several new 

 localities for the rare moss Acaulon triquetrum in Hungary, having
