Under the title * Katur und Gremuth,' M. Karl von Ilippel has published 
(Berlin, A. Dunker) some popular sketches on North German vegetation, 
principally in its sesthetical and physiognomical aspect. The little work is 
elegantly printed, and written with considerable power. 
Dr. von Krempelhuber, of Munich, has just published the first volume of 
his c History and Literature of Lichenology, from the earliest times to the 
year 1865 ' (' G-eschichte und Litteratur der Lichenologie, von den altesten 
Zeiten bis zum Schlusse des Jahres 1865). This promises to be of im- 
portance, describing the progress of Lichenology, giving the title of every 
publication having a bearing on the subject, in chronological order, and com- 
plete references to all known Lichens. The volume (price 10s.) may be ordered 
through Messrs. Williams and Norgate. 
Dr. E. Kostan, San Germano Pignerol, intends to dispose of his duplicates 
of European plants at 20 francs per hundred (where not less than one hun- 
dred species are selected). Botanists who desire to see the catalogue of about 
6000 species of vascular plants may communicate with J. Boswell Syme, Esq., 
70, Adelaide Road, Haverstock Hill, London, N.W. Dr. Rostan has in pre- 
paration a catalogue of about 2000 cellular plants. 
In the ninth volume of the ■ Transactions of the Brandenburg Botanical 
Society/ Dr. Hegelmair has published an important paper on CallitricJie, sys- 
tematically considered. The paper must be regarded as a supplement to his 
previous one, and enumerates eighteen species ; Callitriche umbonata, Sonderi, 
Nuttalli, maryinata, and antarctica, being illustrated by figures. The species 
enumerated as having been found in Great Britain,— Watson, Babington, and 
Syme being the principal collectors,— are C. verna, L., C. stagnalis, Scop., C. 
hamulata, Kiitz., C. pedunculata, De Cand., and C. auctumnalis, L. Dr. 
Hegelmair controverts the views advanced by Mr. B. Clarke in this Journal, 
with regard to the systematic position of Callitriche near Caryophyllece, and is 
inclined to uphold the arrangement which brings it near Hippuris, Myrio- 
phyllum, and allied genera. A contribution to our knowledge of Callitriche 
may shortly be expected from the pen of Dr. Engelmann, and will be printed 
in the 'Transactions of the St. Louis (Missouri) Academy.'

tums, has just been published at Leipzig. The whole of it is in Latin. M.
