not be overlooked, the perfect specimens being exceedingly elegant, 

 and having none of that dark, rigid, gaunt growth which is apparent 

 in every well-grown plant of the common C. nigra with rays that I 

 have seen. I should add that this dissimilarity is by no means so 

 striking in the dried specimens. 



I may also add that I have discovered Polypodium calcareum 

 growing sparingly in a stony thicket on Windlass Hill, in the same 

 neighbourhood : its occurrence on Cleave Hill, three or four miles 

 distant, has been previously recorded by Mr. James Buckman, in his 

 Flora of the neighbourhood, and by Mr. Edwin Lees : the specimens 

 I found were large and densely " glandular-mealy." P. Dryopteris 

 is not found in that locality.

Notice of Leighton's Shropshire Ruhi. 



We are enabled to insert below a hst of the Forms of Brambles 

 comprised in the Fasciculus of Dried Specimens of Shropshire Rubi, 

 just issued by the Rev. W. A. Leighton, author of ' Flora of Shrop- 

 shire.' Tlie basis of the work has been the specimens authenticated 

 by Esenbeck, Bon-er and Lindley, from which the descriptions in the 

 * Flora of Shropshire ' were framed. To these many others have been 

 added, which subsequent research has brought to light — and the whole 

 are now named according to the nomenclature adopted by Mr. Babington 

 and Dr. BeU-Salter in Babington's Synopsis. The work may be re- 

 garded as a revision of the genus Rubus in the ' Shropshire Flora ' — 

 and shows the present views of the author. The specimens selected 

 are generally speaking typical forms — and are carefully and well dried. 

 To botanists generally, the work cannot but prove interesting, and to 

 the student of this difficult and perplexing genus, particularly useful 

 and valuable. The impression {technically speaking) is necessarily 

 limited — and we understand that above one half of the copies are 

 already sold an(l distributed.
