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 oi Spergularia as 

 a generic name by St.Hilaire (1829) or Presl (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 our 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 oryzo'ides 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 oi F. rubra (Linn.), whereas 

 apparently it really belongs to a plant very closely allied to, if not a 

 variety of, F. 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 tbat 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.
