elature, so that Bartramia pomiformis, Hedw., and Philonotis 
fontana, Brid., retain their familiar names. 
The descriptions are lucidly drawn up, and the plates give just 
the features necessary for the determination of the species. The 
forthcoming part will conclude the Acrocarpi. 
New Zealand Mosses . B. Brown, Trans. N. Zeal. Inst., 1892. 
In two very interesting articles, illustrated by thirteen plates, 
we have first an account of the New Zealand species of the genus 
Andraea, which we are somewhat surprised to learn are twenty- 
one in number, of which sixteen are described as new. The 
second article deals with a new genus, Hennedia, including three 
species. 
Hennedia. — Annual or perennial plants. Capsule erect or 
inclined, ovate or ovate-oblong, symmetrical, narrowed towards the 
mouth. Operculum short, stout, conic, straight. Calyptra 
mitriform, large, covering the whole capsule, confluent at the 
base, commonly ruptured at the middle by the lateral growth of 
the capsule ; when maturing very persistent. Peristome none. 
Most nearly related to Encalypta, yet differing from that genus 
in having a short, stout, straight beak, instead of a long, slender, 
straight beak, while the calyptra, instead of being inflated as in that 
genus, closely encloses the capsule, and is confluent at the base. 
Muscologia Gallica. — This excellent work is now approaching 
completion ; the present part deals with the genera Plagio- 
thecium, Amblystegium, and Hypnum in part. A very praiseworthy 
feature is the frequent occurrence of what may be termed cross- 
references ; in other words, in the case of allied species the points 
of agreement and of difference are clearly stated. Such notes are 
of great value to a beginner, and often give a clue to the species 
when the more technical diagnosis fails to do so. The eight 
plates are excellent. The work when completed will form a 
useful companion volume to Braithwaite’s Moss-flora, giving 
British students an idea of Southern forms. 
LICHENES. 
Lichens of the Isle of Man. W. H. Wilkinson. 
We gladly welcome any attempt to popularize the study of 
Cryptogamic Botany, and more especially Lichenology, for 
although there are a few students in Britain, yet it must be 
admitted that the number falls short of what might be expected, 
taking into consideration the richness of our Lichenological Flora, 
the great beauty of the objects themselves, also their important 
bearing on biological problems. The present descriptive and 
illustrated list of the lichens of the Isle of Man, including some
