92 Bibliographical Notice. 
with their localities and such occasional remarks as seemed requisite ; 
and we do not find much that requires our notice, for, of course, 
extracts are impossible. The author retains (as we think, unad- 
visedly) the name of Spergularia, which was given by Persoon to a 
section of the genus Arenaria, as the generic name of a genus called 
Lepigonum (1818) by Fries previously to the use of Spergularia as 
a generic name by St. Hilaire (1829) or Pres] (1819). This is con- 
trary to the laws of botanical nomenclature, according to which a 
term used as the name of a section has no claim of precedence over 
another term given to the same section when first recognized as a 
genus. Impatiens fulva seems to be extending itself along the rivers 
in northern Surrey, and has certainly established its claim to full 
naturalization in England. Salix viridis is a new name, if not a new 
species, introduced on the authority of the great Swedish salicetist, 
Dr. N. J. Anderson. We are unacquainted with it, unless, as sug- 
gested by Mr. Watson, it is oar S. Russelliana. Pinus sylvestris is 
establishing itself on the heaths of the county. Is it not probable 
that this is only a return of one of the aborigines to its ancient 
habitation? There was a time when the Scotch Fir was widely ex- 
tended, as a native tree, both in England and Ireland. The restora- 
tion of the name of Hyacinthus non-scriptus to the Scilla nutans of 
Smith (the Endymion nutans of some modern botanists) rather sur- 
prises us. Surely it is not really a Hyacinthus. Leesia oryzoides is 
stated to occur abundantly by the river Mole. .We are not certain 
that we know what is intended by Festuca duriuscula. Smith 
seems to have given that name to a state of /’.7ubra (Linn.), whereas 
apparently it really belongs to a plant very closely allied to, if not a 
variety of, I’. ovina. 
The latter part of the book is occupied by Appendices. 
Appendix A. “ Plants probably introduced and not thoroughly 
naturalized ;” fourteen in number. 
B. “Plants found on the Thames side, near Wandsworth and 
Battersea, undoubtedly introduced to the locality.’ This is a long 
and interesting list. They were mostly observed by Mr. A. Irvine. 
It seems unlikely that many of them will be able permanently to 
establish themselves. 
C. ‘ Geological Distribution of Plants in Surrey.’’ All the spe- 
cies belonging to the Flora are recited, and their geological position 
marked in a tabular form. 
D. Here the number of species in Surrey is contrasted numeri- 
cally with that of the whole kingdom, by natural orders. It appears 
that the plants of this county constitute three-fifths of our whole 
flora—Dicotyledons three-elevenths, Monocotyledons two-thirds, and 
Ferns and allies one-half of the total number belonging to those 
classes respectively. 
An alphabetical Index of the orders and genera, and another of 
the English names, conclude the volume. 
We heartily congratulate Mr. Brewer upon the production of so 
creditable a Flora of his county, and are sure that it will be properly 
appreciated by botanists out of, and especially in, Surrey.
