88 Species arid Varieties of Plants 



In concluding these notices, I cannot help expressing a wish 

 that in future the pages of this Magazine may regularly be- 

 come the medium of communicating, more definitely than is 

 usually done, the exact stations of all our rarer indigenous 

 plants, by those whose personal knowledge of their habitats 

 enables them to do so with absolute certainty. By following 

 such a course these volumes would prove a most valuable 

 " Botanist's Guide" and faithful record of lost or still exist- 

 ing stations to succeeding times, in place of those vague indi- 

 cations which seldom conduct the botanist to the object of his 

 search. — Hastings, Sussex, 1835. 



Art. VII. An Enumeration of Species and Varieties of \Plants 

 which have been deemed British, but "whose Indigenousness to 

 Britain is considered to be questionable. By the Rev. J. S. Henst 

 low, M.A., Regius Professor of Botany in the University of 

 Cambridge. 



In February, 1835, I sent you a communication respecting 

 the indigenous flora of Britain [VIII. 84 — 88.], with a pro- 

 mise to forward some further remarks, or, rather, the list of 

 plants, marked in the way I have there suggested. When I 

 was about to do so, I found that a second edition of my Ca- 

 talogue was wanted ; and, having determined to insert these 

 notices in it, I now send you the Catalogue itself, from which 

 you can easily extract the names of those plants to which any 

 mark has been attached. 



I am obliged to Mr. Bree for taking up the subject [VIII. 

 386 — 388.]. He will observe that I do not intend to say, 

 that /Vis fcetidissima and Polygonum Bistorta are not truly 

 native. I know that the former is plentiful in the south of 

 England ; and I have found both in Kent in abundance, and 

 evidently indigenous. I alluded merely to one spot where 

 they occur under suspicious circumstances, but have been 

 introduced into a local flora without any comment. 



Cambridge, Nov. 23. 1835. 



[The Catalogue sent is noticed in p. 54. In it is presented, 

 besides some synonymes, designation of these five conditions 

 in application to certain of the species and varieties registered. 



1. An estimation as varieties of certain reputed species. 



2. " Possibly introduced by the agency of man." 3. " Na- 

 turalised, certainly not indigenous." 4. "Occasionally found 

 wild, but not ever naturalised ; extinct ; 'or erroneously intro- 

 duced, and which ought to be excluded from our floras." 5. 

 " Included in the flora of Cambridgeshire."
