succulent and blunt segments ; the flowers smaller than those of its 

 ally ; the involucre truncate at the base ; and the receptacle broadly 

 ovate. Several years since we were shown a plant which seems to 

 possess these characters near Selsea by Mr. Borrer, and informed by 

 him that it is the true plant of Smith. Whatever may become of the 

 maritime plant of other parts of the British coast, we incline to the 

 opinion that this Selsea form is really a distinct species from C. ino- 

 dorum. 



Carduus acanthoides and C. crispus are recorded as inhabiting his 

 district, and, as seems to be the most correct view of the subject, 

 they are retained as distinct species. This is also the opinion of Fries 

 and" of Godron. In Babington's 'Manual' the two names are given 

 to forms of one species which appears to correspond with the C. 

 acanthoides of those distinguished botanists, and as far as we are in- 

 formed, the true C. crispus has not been found hi Britain. 



Polygonum lapathifolum and P. Persicai'ia are divided into P. 

 pallidum (With.), P. nodosum, Pers., P. laxum, Reich., and P. Per- 

 sicaria, Linn., the latter including two subspecies, the P. agreste, 

 Fries, and P. biforme, Wahl. Their characters are taken avowedly 

 from Fries's 'Mantissa,' ii. 23-28. "We have not been able to 

 satisfy ourselves concerning these plants, all of which are probably 

 natives of Britain, although it has long been our desire to do so. 



The Rubi are carefully described, in accordance rather with the 

 views of Godron (Fl. France), than those of Swedish and British 

 authors. The small number of the Glandulosi is remarkable, and 

 will probably be much increased by their further study, as is suggested 

 by the author. 



In the equally difficult genus Hieracium, the views of Fries, as 

 developed in his great work upon this subject (Symbolae ad Historiam 

 Hieraciorum), are followed. 



Usually there are no generic or specific characters given, but in 

 the few cases in which the definitions by Koch seemed to require 

 emendation, or where additional species had to be described, they are 

 added. The total number of species recorded is 1341 : in the 3rd 

 edition of the 'London Catalogue of British Plants,' we find 148/ 

 (without reckoning the "excluded species") : in the ' Edinburgh Ca- 

 talogue,' ed. 3, there are 1/15. We have not time to count the spe- 

 cies described in Babington's 'Manual,' ed. 3, but believe that it falls 

 short of the latter number, although much more considerable than the 

 former, which is reduced by the exclusion of very many species of the 

 "critical" genera, such as Rubus and Hieracium, and the reduction 

 to the rank of varieties of numerous other plants, considered as species 

 by Babington and the Edinburgh botanists. If we bear in mind that 

 the ' British Flora ' includes a considerable number of western and 

 arctic species, and that the Batavian list is confessedly imperfect in 

 several of the less known genera, it will be seen that the flora is fully 

 as great as was to be expected, when the nature of the country is re- 

 membered.
