Scirpus Tabernsemontani Gmel. in Aberdeenshire. In 



the summer of 1887 examples of this plant were sent to me by Dr. T. Jamieson, 

 which had been found by himself beside the River Ythan, at no great distance 

 below Ellon. The species has not previously been recorded from any locality 

 between Forfar and Easterness ; the new locality is in North Aberdeenshire.

NEW WOEKS ON BRITISH BOTANY. 



Two important monographs, dealing with difficult and critical groups of 

 British plants, will soon be published ; and intending subscribers are requested 

 to send their names to the respective authors. 



The British Hieracia will be described and illustrated very fully by Mr. 

 F. J. Hanbury, F.L.S. (69 The Common, Upper Clapton), to whose visits to 

 the North of Scotland in recent years we owe many new county records. Mr. 

 Hanbury has made a most careful study of this very difficult genus ; and the 

 monograph will have peculiar value for Scotch Botany, as the Hieracia are so 

 numerous in our Alpine and Northern flora. It is to be published in parts in 

 five years, and will cost about ^. 



The British Uredine^e & Ustilagine.*: will form the subject of a 

 volume (price 7s. 6d.), by Mr. C. B. Plowright, F.L.S. (King's Lynn, Nor- 

 folk), whose name is a guarantee of the value of the work, on which he has 

 been engaged for a considerable time. The life-histories of these fungi are so 

 interesting, and their parasitism on many cultivated plants is frequently so in- 

 jurious, that it is unnecessary to dwell upon the great importance of a full know- 

 ledge of them. We are certain that the monograph now announced will place us 

 abreast of the most recent discoveries in regard to both groups of fungi ; and 

 that It will be indispensable to Mycologists.
