the Continent. A few species, viz. four, Neottia gemmipara, Sisyrin- 
chium anceps, Eriocaulon septangulare, and Naias flexilis, seem to point 
to a former connection with North America; of seventy species be- 
longing to the Atlantie type, Ireland contains 41; those of the Ger- 
manic type are few, 18 only out of 127 ; Ireland contains rather more 
than one-third of those belonging to the Highland type, these are 
chiefly confined to the north and west; those of the Scottish and 
intermediate types are more numerous, viz. 66 out of 117. Of 1425 
species* given by Mr. Watson as the total number of the British 
flora, Ireland contains about 950 ; adding to these, plants which occur 
in Ireland but not in Britain, and various Hieracia and Rudi, the 
authors compute the whole Flora at about 1000 species, and therefore 
even at the lowest estimate, considerably under the number found in 
Britain. The species found in Ireland but not in Britain are 22 in 
number, or, rather, say 19,—doubtful species of Sazifraga being ex- 
cluded ; these, with one exception, are confined to the south and west. 
Of the deficiencies in the Irish Flora only a few are specified; we 
think that a full list ought to have been given, as being a point of con- 
siderable interest. 
In order to afford a general idea of the range of each species, the 
authors have adopted the divisions proposed by Professor C. C. 
Babington, in a paper read before the Dublin University Zoological 
and Botanical Association in 1859 ; the particulars of the twelve dis- 
tricts and their characteristic plants are described in the introduction, 
and fully illustrated by means of an excellent map, The remainder of 
the introduction embraces a list of the species and a tabular view of 
their range in Ireland. 
In the body of the work we have minute information respecting each 
plant. A single example will suffice :—

Some € —— this an over-estimate, there being different opinions 
as to what p to rank as species.
