leaflets, the exactly cuneate form of the segments, which are either en- 
tire or bifid. The base of the leaves, and the top or collum of the

Botanical News from Italy. 
Florence, 16th August. 
You will no doubt have seen by the newspapers the progress and 
ravages of the disease of the Vine in Italy; I will not therefore revert 
to the subject, nor give any detailed account of what has been lately 
published concerning it, but rather proceed to notice a few publica- 
tions more particularly botanical. 
I shall first mention a work by Professor Massalongo, of Verona, 
entitled, “Ricerche sull? Autonomia dei Licheni crostosi, e materiali 
pella loro naturale ordinazione.” It contains an abridged history of 
all those crustaceous and pustulous Lichens which the author has been 
able to study on living specimens, with a view to determine the limits 
of their development and their specific characters; they are divided 
into seventy-one genera, twenty-one of which are new. This work 
forms an octavo volume of 224 pages, illustrated by 400 microscopic 
figures representing the thecze and spores of the species described ; its 
_ price is 20 francs. A kind of supplement to it will soon appear, under 
the title * Memorie Lichenografiche,’ containing descriptions and figures 
of the other orders of Lichens.
