will it fare with " sixty three " species of Rubus long before the end 

 of this century. 



Of Agrimonia odorata, of Aiton, we are compelled to confess entire 

 non-acquaintance, unless an indifferent Cornish specimen shall prove 

 an English representative thereof. The specific character given in 

 the ' Hortus Kevvensis ' amounts to no character at all as a distinction 

 from our ordinary A. Eupatoria. The A. odorata is said to be a larger 

 plant, with deeper-coloured flowers, leaves hairy and glandular be- 

 neath, not cano-tomentose, calyx less furrowed, and with the lower 

 spines reflexed. The latter character exists in the pressed specimens 

 of A. Eupatoria.

Note on the Disappearance of Plants in certain Localities. 

 By Thomas Meehan, Esq. 



Many botanists cannot have failed to observe that certain plants 

 often exhibit a remarkable degree of inconstancy in some localities 

 with regard to quantity. Sometimes a locality which is known to 

 produce a large quantity of any given species, will barely produce a 

 handful; sometimes it will even totally disappear in that, and reappear 

 in no situation near the other. Usually, however, if they disappear 

 in one locality, they may be found in some situation near to the for- 

 mer one, which occurrence may perhaps be termed a migration . The 

 following example may probably illustrate this better : it is a case of 

 the Sisymbrium Sophia, which, in a work I have now before me by 

 Dr. Pulteney, ' Catalogues of the Birds, Shells, and some of the more 

 rare Plants of Dorsetshire,' published in 1813, is stated to "be met 

 with near the Ferry, on the Ham side of the water, at Poole," but now, 

 and I am indebted for the knowledge of this fact to Dr. Bell Salter, it 

 may scarcely be met with there, but is in great plenty in a situation 

 a little distance from this. 



Circumstances may often be met with in the Isle of Wight, which 

 bring these observations repeatedly before the memory, and which in- 

 cite the ardent admirer and devoted lover of Nature to an investiga- 

 tion of the causes that may lead to such curious results. 



There are many plants that certainly existed in the Flora of the 

 Isle of Wight that are now missing; and there are many that have 

 been reported to exist by various accurate observers, that have hitherto 

 been vainly sought for. Among the former may be mentioned An-
