whence the generic name ; but this is not a constant generic cha- 
racter. . 
The distribution of the genus is mostly tropical, sub-tropical 
and antarctic (regiones tropicas, calidas et antarcticas præsertim 
maritimas insulares habitans — C. M. Syn.). It includes some 75 
species, of which some 40 may be described as austral and 
’antarctic, 30 as intertropical, while only 5 species have hitherto 
been found north of the Tropic of Cancer ; of these one, D. Mai- 
baræ is from Japan, and the remaining four from Northern India 
(Khasia, Sikkim and the Himalaya). With the exception of these 
four none are recorded from extra-tropical continental Asia, from 
North Africa, Europe, or North America. There are few genera 
therefore which one would less expect to intrude into the conti- 
nental regions of Europe, and the occurrence of an undescribed- 
species of Distichophyllum north of the main range of the Alps is. 
a vagary of geographical distribution which out-rivals even the 
remarkable recent discoveries of Lalymperes Sommieri and Bar 
bella strongylensis in the Mediterranean Islands. 
During a visit in the summer of 1908 to the Alps of Salzburg 
and Upper Austria, we spent a very pleasant week at St-Wolf- 
gang on the St. Wolfgang-or Aber-See, at the foot of the Schaf-. 
berg, a limestone peak with a very rich and beautiful flora. This 
part of Salzburg, lying on the confines of Upper Austria, has it 
would seem received but scant attention on the part of bryolo- 
gists. The records from Salzburg in the older bryological works, 
in Juratzka’s Laubmoosflora von OEsterreich-Ungarn, and in 
. Loeske’s Bryologische Notizen aus den Salzburger und Berchtes- 
gaden Alpen apply almost exclusively to the Pinzgau Alps, and 
the immediate neighbourhood of the city of Salzburg. 
On the opposite shore of the St. Wolfgang See lie one or two 
small villages, and behind these towards the South and South- 
west the mountains rise in steep wooded ridges intersected by 
deep ravines, up to peaks varying from 1500 to 2000 mètres in. 
- height, forming a wild and practically uninhabited mountain mass 
extending for 20 miles or so between the valley of the Salzach on 
the west, and the chain of lakes, connected by the Traun and Ischl 
rivers, on the east. One of the finest of the intersecting valleys, 
and perhaps the most accessible from St. Wolfgang, is that for- 
med by the Zinkenbach, whick, taking its rise on the Hohe Zin- 
ken, a bare craggy peak 1762 met. in height, forms a deep and. 
beautifully wooded ravine, five or six miles in length, before it 
empties itself into the St. Wolfgang See just opposite St, Wolf- 
gang village. À very pleasant day was spent in exploring the 
lower part of this ravine. Our intention had been to reach the
