106 NOTICES OF BOOKS. 
the Natural Order, the Linnean Class and Order, the generic, 
specific, and common name of the plant, together with the syno- 
nyms of the botanists whose names are mentioned in the title. 
To these is added the general habitat; and blank spaces are left 
for the precise locality, the time of gathering, and the name of the 
collector. “As each plant has one or more labels assigned to it, 
whenever the writers above-mentioned differ in their nomenclature, 
all will be able to select that of their favourite text book, while the 
synonyms attached will show the arrangement adopted by the 
other three authorities, and thus, to the less advanced student, 
. tend, in some degree, to increase the facilities of botanical inter- 
course.” : 
We gladly recommend this collection of labels to every person 
who forms a British Herbarium; for the neatness of printed 
labels over written ones is manifest to all, and they yet bear, or 
ought to bear, enough of the writing and the name of the collector 
to carry the stamp of his authority. 
Synopsis HrPATICARUM ; auctoribus GOTTSCHE, LINDENBERG et 
Ners AB EsENBECK. Hamburg. 1847. 
This valuable work, the earlier portion of which we noticed in 
the fourth volume of the present Journal, is now happily brought 
. to a conclusion in one thick volume of upwards of eight hundred 
: pages, with a copious Index, and a Supplement of no less than 
13 one hundred and eighty-one pages “species complectens et 
synonyma præstantiora, quæ dum liber hic imprimebatur ab aliis 
descripta innotuerunt;" that is, during a period of three years 
only. Such is the rapid progress in the present day of this 
department of Botany. A Conspectus Generum shows that the - 
learned authors have divided the Hepatice into five tribes ; viz., 
l. Jungermanniacee ; 9. Monoclee ; 3. Marchantice 3 4. Antho- 
cerotee ; 5. Riccie; and into seventy-two Genera. It is a work 
that must be in the hands of every student of Cryptogamic Botany, 
_ whatever may be his views respecting the proper limits of genera 
and species.
