210 SUMMARY OF CURRENT RESEARCHES RELATING TO 



Moss-flora of Hamburg.* — E. Timm publishes a contribution to 

 the bryology of the Hamburg district, consisting chiefly of the more 

 important finds made by Wahnschaff and himself since 1900. He 

 gives a brief resume of the work done by previous authors. The total 

 moss-flora is about 450 species. A curious unexplained problem is the 

 occurrence of the saprophytic moss, Tetraplodon mnioides, a mountain- 

 dweller, down in the plains near Geestemiinde, Hamburg, and 

 Magdeburg. The suggestion that the spores have been carried by 

 blow-flies from the Brockeu in the Harz Mountains does not meet the 

 difficulties of the case. The occurrence of many so-called mountain 

 species on boulders in river gorges leads to the reflection that such 

 boulders are much commoner in the mountains than in the plains, that 

 such species are boulder-dwellers, and that altitude has nothing to do 

 with the matter. The author enumerates 208 mosses and 32 hepatics, 

 interspersing them here and there with notes and figures. 



Mosses in the Peat on the Baltic Coast.f — 0. A. Weber, in a 

 further note on the mosses in the peat on the Baltic coast between 

 Sarkau and Cranz, states that he has examined the original material 

 referred to Hypnum turgescens by C. Miiller (Halle) in 1867, and finds 

 it to be Seorpiurium scorpioides. He points out its distinguishing 

 characters. He also states that the fragments referred to Hypnum 

 niteas by C. Miiller are H. exannulatum, and shows how the mistake 

 probably arose through insufficient care in removing the leaves from the 

 stems. 



Mosses of the Eastern Alps 4 — W. E. Nicholson gives an account 

 of a bryological excursion made by him with H. N. Dixon in August 

 1904 to South Tyrol and Carinthia, with a brief visit to Lago di Garda 

 and Verona. Nine days were spent at Sulden and six at Heiligenblut. 

 An enumeration of 120 mosses with localities and occasional notes is 

 added. 



Some Hungarian Mosses.- — I. Gyorffy§ gives an account of the 

 moss Coscinodon cribrosus (Hedw.) Spruce and shows that it is a xero- 

 philous species, as is proved by the character of its leaf-structure. He 

 indicates some new stations in Siebenbiirgen (Transylvania). The same 

 author || describes with much detail the mosses (1) Bruchia palustris 

 var. Deg&nii, which represents the addition of a genus to the Hungarian 

 flora ; and (2) Meesea trichodes var. alpina and var. minor. The struc- 

 ture of the plants is beautifully illustrated. The text is in both 

 Hungarian and German. 



Russian Bryology. — A. A. Elenkin 1 publishes a preliminary account 

 of the lichen and moss formations in middle Russia. A. A. Sapehin ** 

 gives an account of the distribution of the moss formations and of the 

 species in the western part of the Taurus mountains in the Crimea.
