Ilypericnm anr/licwii, Bert. This is one of the " doubtful species '" of 

 the London Catalogue, and it may with reason be doubted whether it has 

 ever occurred in England, save in gardens. It is the H. elatum of English 

 Botany, and the H. grandifoliwn of Choisy : and has frequently been con- 

 fused with H. Androscemum, and H. hircinum. Mr. J. T. Syme in Phyt. ir. 

 120. O.S. thus directs attention to it : "A Hypericum appearing to be this 

 species, was observed by Dr. Balfour in large quantity, apparently wild, on 

 the banks of the Glaumire Biver, near Cork ; the plant had also been seen 

 by Mr. Sibbald at Agbada." Professor Babington, however, is inclined to 

 consider the species here found as H. Uircinum. Mr. Isaac Carrol, in 

 Phyt., V. 77. N.S., remarks, " I have long observed this plant on walls by 

 the road under Lota Wood, Glaumire, Cork ; but do not think it can be a 

 native ; and this locality may be in close proximity to the one above-men- 

 tioned. In 1855, Professor Babington again brought forward the claims 

 of H. anglicum to be considered as a British plant, in a paper, read before 

 the Linnean Society, of which the following summary appeared in Phyt., i. 

 117. N.S. " Mr. B. is disposed to think that the true H. anglicum of 

 Bertolini still exists in Britain : a specimen agreeing with it in character 

 was found by Mr. T. Polwhele about Falmouth harbour, Cornwall ; and 

 specimens of the same kind are in Dr. Balfour's herbarium, gathered by 

 him on the banks of the Crinan Canal ; Galway, Ireland, [in 1833^ ; and 

 Culross, Perthshire, in [1838]. H. anglicum is represented in EngUsh 

 Botany, t. 1225, under the name of H. Androsirmum." Mr. GiiTord, at page 

 518 of the same volume, quotes a letter from Miss Warren, having refer- 

 ence to its occurrence at Falmouth, in which she observes : " The idea of 

 H. anglicum being a Cornish plant is now, I think, entirely set at rest. It 

 has been proved to be H. hircinum in every locality in this. neighbourhood 

 where found by all explorers, and the same as yours, which still keeps its 

 ground at Swanpool." With reference to this quotation. Professor Babing- 

 ton remarks, " I cannot agree that ' the idea of H. anglicum being a Cor- 

 nish plant is entirely set at rest.' Unfortunately, I do not possess the 

 means of communicating with Mr. T. R. Polwhele, and so cannot learn
