Rubus C(Bsius (L.), the last on our list of Selborne Rubi, need not 

 detain us long, being so well known. It is, however, not a little re- 

 markable, that, loving damp shade as this plant usually does, and 

 abounding as is Selborne in shady streams and woods, the dewberry 

 nevertheless appears here always to choose sunny exposures. It was 

 consequently of rather stout habit, but always trailing ; it was, too, 

 notwithstanding such exposure, the true casius, and not at all inclin- 

 ing to pass into dumetorum, which, according to Mr. Lees' opinion, 

 it should have done in such situation. 



This remark brings me to speak of my promise (Phytol. ii. 99) to 

 speak of Mr. Lees' third instance of species or supposed species dedu- 

 cible from R. caesius. This instance is mentioned in the paper before 

 quoted, in the ' Transactions of the Botanical Society of Edinburgh' 

 (part iii. p. 177), and refers to a form which Mr. Lees is disposed to 

 call aenosus. If this form be, as is there mentioned, Mr. Leighton's 

 " 1-hamnifolius, second form" I think its true affinity will be found, 

 not with cceftius, but with affinis, as I have already remarked in this 

 paper (Phytol. ii. 101). Mr. Lees also speaks of deriving some form or 

 forms called " corylifolius " from this species, but this need not detain 

 us. This term is so vague, and has been so variously applied, that it 

 is not unlikely forms of caesius, as well as of other species, may often 

 have been so called ; and I should gather from the tenor of Mr. Lees' 

 remarks, that his experience is the same as mine, when I say that I 

 have not met with a specimen labelled with this name, which might 

 not rightly be referred to some other species. Being thus so totally 

 ignorant what ought to be intended by E,. corylifolius, I must leave 

 this suggestion of Mr. Lees, only expressing generally the opinion 

 that I believe R. caesius to be one of the most natural of our species, 

 though to a considerable extent a variable one. 



Doubtless Selborne contains many other forms of Rubi, besides 

 those noticed in these remarks, but these are all I observed during my 

 " Tliree Days' Botanizing at Selborne,''' — three days I am not likely 

 soon to forget.
