for marking Desiderata in Exchanges of Specimens ; for indi- 

 cating the Species of local districts ; and for a guide to bota- 

 nical collectors, by showing the comparative rarity or frequency 

 of the several species. London : William Paraplin, 46, Frith- 

 street, Soho. 1844. 



The title of this Catalogue, which we have given at full length, 

 will sufficiently explain the objects proposed by the compilers. It 

 may be had either as a large broadside, like the earlier edition of the 

 Edinburgh Society's list, or as an 8vo. pamphlet. The arrangement 

 adopted is that of the natural system ; and the nomenclature, in ge- 

 neral, that of the fifth edition of Hooker's ' British Flora.' The spe- 

 cies are numbered continuously from 1 to 1428; "that being deemed 

 the most convenient method in a Catalogue, designed to be used as 

 an Index to herbaria and duplicate stores." For an index to herba- 

 ria we have always had a predilection for the plan of numbering the 

 genera continuously, and giving a new set of numbers — beginning 

 with 1 — to the species under each genus : but this may be merely a 

 matter of opinion. The list of Salices has been drawn up by the Rev. 

 J. B. Leefe ; and the arrangement of the Rubi was entrusted to Mr. 

 Edwin Lees. The two gentlemen who have undertaken the arrange- 

 ment of the species of these difficult and ill-understood genera, are 

 well known to have devoted their attention to this particular subject 

 for many years past. A list of about a hundred species is given, be- 

 ing such as are considered " either scai'cely naturalised, or not re- 

 cently found in the localities indicated for them : " and the names of 

 "introduced species, now more or less naturalised, are printed mita- 

 lics." The number of species &c. is thus summed up : — 



Indigenous Species, 1305 



Naturalized Species, 132 



Excluded Species, 102 



Varieties, 495

 From the numerous enquiries which have been addressed to us re- 

 specting a list of plants arranged on the natural system, we have but 

 little doubt that the London Catalogue will attain a wide circulation 

 among British botanists, without at all interfering with any of its pre- 

 decessors, which may have been arranged on a different plan.
