Belgian and Italian forms. Mr. Mudd has followed this method, and 
subjoins to his paper very full and satisfactory examples of all his 
species, and upwards of eighty of his forms, so that altogether his work 
possesses that commendable thoroughness which, when a monograph 
lacks, it stands without excuse. 
The only fault which we have to find is on the score of nomenclature. 
It seems to us that the lichenists are causing themselves considerable 
needless confusion by not following the received rules with regard to 
the adoption of names and citation of authorities for them. Scheerer 
is the principal offender in this respect. To cast aside the widely- 
accepted Linnzean name of uncialis, and re-christen the plant stellata, 
as Scherer has done, and Keerber, Rabenhorst, and Mr. Mudd have 
followed him in doing, is quite contrary to rule. Mr. Mudd's “ Cla- 
donia endiviafolia, Ach.," is just Hudson's Lichen foliaceus (1778). 
The name endiviafolius goes back as far as Vaillant and Micheli, but 
in post-Linnzan times Dickson was the first to apply it, whilst 
alpestris and sylvatica, for which Mr. Mudd cites Hoffman and 
Acharius, both go back to Linnzeus. 
About the spermogones of Cladonia vermicularis, a doubtful plant 
altogether, the lichenists are widely at issue. What Dr. Nylander 
considers as the spermogones of the C/adonia, Mr. Mudd refers to a 
new parasitic Endocarpon, which he describes here under the name of 
E. Crombii; and what Dr. Lindsay considers as such he credits to a 
Lecidea. As the readers of the Journal will already be prepared to 
understand from what Mr. Carroll has told them, since the publication 
of the Manual in 1861, a large number of Lichens new to Britain have 
been detected, and Mr. Mudd intimates that a revised edition of that 
work is in preparation. 
Notes sur quelques Plantes rares ou critiques de la Belgique. Cinquième 
fascicule. By Professor Crépin. Brussels : Gustave Mayolez. 1865. 
8vo, 274 pp. with 6 plates. 
The establishment of the Royal Society of Botany in Belgium has 
given a great impulse to the study of its indigenous vegetation, and 
Professor Crépin has in this, the fifth part of his notes, to register the 
discovery of fourteen novelties, in addition to eight species now clearly 
established as Belgian plants, which before were classed amongst the 
* doubtfuls.” These twenty-four species are the following, viz. :
