mediate region was hitherto uninvestigated as to its bryological flora, but wa;s 

 naturally found to be closely similar to that of corresponding areas in the better 

 known Baltic Provinces. A complete list of the species of bryophytes found is 

 given with careful details as to habitat, etc. A new Bryum androgynum is 

 described (by Warnstorf) and figured, and the author also includes a new variety 

 pleskowiensis of Seligeria recurvata with figure, remarking that it is very near 

 5. campylopoda Kindb. and suggesting that critical revision might reduce the 

 number of species of Seligeria. The region investigated lay well behind the 

 Russian lines through 19 17, but has since been the scene of considerable fight- 

 ing. That a scientific work of the sort could be published in Riga under the 

 disturbed conditions of 1919 is remarkable, that it is printed in German is hardly 

 less so.

This contains two distinct papers, one on Macedonia and the other on the 

 Transylvanian Alps. The author was actively engaged in operations at the 

 front in the Balkan theatre of war, taking part in the campaign against Rumania 

 and serving a year apparently with a German unit cooperating with the Bul- 

 garian forces in Macedonia. In the latter service he was stationed in the criti- 

 cal sector of the Cherna bend, where he was able to study intensively a limited 

 area, whose moss-vegetation was hitherto unknown. The flora proved to be 

 predominantly Mediterranean, though lacking some of the latter's character- 

 istic elements. A list of mosses (102) and hepatics (12) is given with localities 

 and some critical notes. Orthotrichum insidiosum is proposed as new, also 

 Mielichhoferia paradoxa found in three stations, a quite new type which is even 

 generically hard to place. It appears to be one of those relicts of tropical or 

 more remote relationship, of which a number have been discovered among the 

 mosses of southern Europe within recent years. It is compared with Bryum 

 splachnoides (Harv.) C. M. originally described from India, but now known 

 from several localities in southern Europe, from which species it is said to be 

 entirely distinct. 



The Transylvanian collections were made during the active operations of 

 the invasion of Rumania in the border mountains of the region of Roter Turm 

 Pass, etc. The list is not meant to be complete, though a very extensive one 

 under the circumstances. The Carpathian moss-flora was known to some 

 extent before, and no startling finds were made, but a good idea of the essential 

 facts is given.
