anywliere yet. Salix acutifolia (a willow, representing a group 

 not known in this country before its discovery), was announced 

 (by myself) as a British plant, and described in the February 

 *Phytologist.' It might be interesting, too, to tell the Club, that 

 a Galium, which grows amongst the rocks below the "V\'Tiite Force, 

 Teesdale, is most likely a species not acknowledged as British. 

 I have not yet been able to arrive at a definite conclusioii about 

 it ; but when I showed specimens to Jordan, of Lyons (the great 

 authority upon the genus*), he thought it was most likely the 

 plant which he has described under the name of Galium com- 

 mutatum. Your Club might investigate it next time they make 

 an excursion in that direction. 



"In Ferns, the third edition of Newman's History, a work 

 admirable both as a popular and scientific history of our indige- 

 nous species, has made its appearance during the year, proposing 

 various considerable alterations in nomenclature, and containing 

 descriptions of several real or supposed species, which have been 

 discovered since the publication of the second edition. This 

 morning I received a prospectus — a work to represent the 'Bri- 

 tish Ferns by the nature-printing process, as practised at the 

 Imperial printing office at Vienna' — to be edited by Moore and 

 Professor Lindley, and to be completed in twelve or sixteen 

 monthly parts. 



" As regards Mosses, Wilson's long-expected work will doubt- 

 less appear very* shortly. You may form an estimate of the 

 progress which has been made in Bryology during the last few 

 years, by the fact, that our work for Yorkshire (a single county 

 alone), enumerates about the same number of species as the 

 latest descriptive work — Sir W. Hooker's Flora — for the whole 

 of Britain. There is though, as might naturally be expected, 

 no other county that can nearly come up to ours in this respect. 



"In Lichens, has been published Leighton's Monograph of 

 the British Graphidece, which contains exceedingly elaborate 

 descriptions and drawings of the British representatives of the 

 class, and proposes to arrange them under several genera, instead 

 of one or two. In Yorkshire, Mr. Mudd, of Ayton (who was
