Results of a Bryological Visit to Portugal. 
In May,1911, Mr. W.E. Nicholson and Ipaid a long desired visit 
to Portugal. Our principal object was to study the flora, particu- 
| à larly the Bryophytes, of Algarve, the extreme south-western 
part of the country. The Hepaticæ collected by Mr. Nicholson 
| are being dealt with separately by himself; the present article 
refers to the Mosses alone. 
Several considerations attracted us to that particular part of 
Europe. Bryologically it is a little known district. Count von 
Solms-Laubach visited Algarve in 1866, and published the 
account of his observations in his Thesis « Tentamen Bryo- 
Geographiæ Algarviæ Regni Lusitani Provinciæ ». Subsequent 
to his visit it is doubtful whether any bryologist has visited the 
province; while even in northern Portugal the names of those 
who have collected mosses may almost be counted on the fingers 
of one hand. 
The bryological flora of this south-western corner of Europe 
might be expected to be of some interest. The remarkably con- 
nected « Atlantic» floras of Britain (especially of the South-west 
and west of England and Ireland) and of the Atlantic Islands find 
many links along the western shores of Europe from Brittany to 
the Pyrenees and Portugal, and further confirmation of this 
might be looked for in the southern province, where the climate 
more nearly approaches that of the Atlantic Is. than in any other 
_ part of Europe. This presupposition was amply borne out by 
= Solms-Laubach’s investigations. Such mosses as Fissidens ser- 
_ rulatus, Ditrichum subulalum, Brachysteleum pulvinare (since 
= found to be identical with the Pilychomilrium nigricans of the
