in the standard descriptions. The end-cell of the lamella varies in 

 form in the same leaf according to its height above the base of the leaf ; 

 the lamellae also vary according to the age of the leaf and the degree of 

 soil moisture, and in fact depend upon the environment. The author 

 adds notes on other Polytrichace^e. 



German Mosses. — H. Brockhauseu * treats of the geographical and 

 ecological distril)ution of Tetraplodon mnioides in Germany. His ob- 

 servations of the plant were made in Northern Westphalia, where it grows 

 in damp places among hejither, in sunny pine-woods, on dry sandy 

 roads ; it prefers to grow on old bones and teeth of hares, rabbits, and 

 mice, and rarely on dogs' excrement : and it avoids chalk. It is peren- 

 nial and fruits very freely between April and September. It is a low- 

 land and not a highland species. V. Schiffnerf gives a list of the more 

 interesting species in a collection of Muscineai made by Y. Patzelt in 

 the neighbourhood of Reichenhall in Bavaria. Three hundred species 

 were collected at altitudes of 1500-2000 ft. ; among them are several 

 subalpine plants which have descended unusually low. 



Moss-flora of the Harz.J — H. Zschacke publishes a second contribu- 

 tion to the moss-flora of the Duchy of Anhalt, treating specially of the 

 north-east Harz mountains, a district well known through Loeske's 

 Harz Flora. The author gives word-pictures of a dozen stations 

 between the altitudes of 1000 and 1900 ft., in which he describes then- 

 moss-clothing and thus affords some interesting comparisons. Equally 

 interesting are the four tables enumerating the mosses which find in 

 this region their north, south, east and west limits respectively. 



Swiss Mosses. § — R. Keller publishes a third contribution to a 

 knowledge of the moss- flora of Canton Unterwalden. He gives a list of 

 152 species collected in the neighbourhood of Stanzstaad, Kerns, and 

 Melchthal, determined bv J. Weber. 



Old Bohemian Moss -records. || — F. Matouschek has been examining 

 the mosses in the Landes Museum at Prag, and publishes a revision of 

 the older records, made by the native botanists between 1817 and 1860, 

 taking special note of the determinations of Opiz, which he converts into 

 modern terminology. 



Hungarian Mosses. — M. Peterfi f publishes some contributions to 

 the Sphagnum-flora of Hungary, founded on material preserved in 

 various public and private herbaria. He calls special attention to the 

 high moorland of Bory in Arva which is the richest station in Hungary 

 for Sphagnaceae ; and one of the commonest species occurring there is 

 S. molluscum. Two species and nine varieties are new to the flora. A 

 long critical note is appended to S. subtile Warnst., a species intermediate 

 between S. ruhdhim and S. amtifolium. I. Gyorffy** records the sporadic
