66 The Irish NaUiralist. [Marcli, 



Ireland. The first two ma}^ be, as Mr. Hart says they are, 

 rare in the West, and the third, rare in most parts of Ireland, 

 away from the large lakes or rivers ; but we consider that our 

 word, " frequent," most fully expresses their known standing 

 in Ireland as a whole. The generalisation that the three 

 species, Lysiviachia vulgaris, Euphorbia Paralias, and 

 Parietaria officinalis are rare in Donegal we did not think 

 it prudent to adopt before we had seen Mr. Hart's final 

 views on the subject in his county flora. The Flora, 

 unfortunateh^ did not appear until the 2nd edition of Cybelc 

 had passed through the printer's hands. Our critic is in error 

 in supposing that Lysimachia vulgaris is in District XII. 

 confined to Lough Neagh, as there are two recent records for 

 stations in County Down remote from the Lough. He is also 

 in error in supposing Euphorbia exigiia to be absent from 

 West Ireland : it occurs in District VI., and its rarit}^ in the 

 West we have sufficiently indicated by the statement in Cybele : 

 " not yet recorded for Kerr}^ West Galway, Mayo, or Sligo." 

 Finall}', last item in this long list, comes Empetru7n nigrum. 

 We have fully noted in Cybele the occurrence of this species 

 at low levels in man}^ parts of Ireland ; but we still consider 

 it to be essentially a mountain plant in the West, as well as 

 in the East, and rare at low levels. 



Page 40 of the Remarks presents us with an other list, chiefly 

 made up of plants which, in Mr. Hart's opinion, have been 

 improperly relegated to our Appendix. We need not discuss 

 this list in detail, as it deals almost entirely w^ith debatable 

 matter; but we feel bound to more fully notice one item, 

 Heliayithemum vulgare. We still consider it inadvisable to 

 concede to this plant a place in the Irish flora proper. Fuller 

 information is needed, above all, as to the quantity in which 

 it appears in the Donegal station. We do not know whether 

 Mr. Hart found a thousand plants there or only a single 

 plant ; and we hope he will further examine the craggy 

 district he refers to at the earliest opportunity and publish 

 the results of his investigation. In the paragraph introduc- 

 tory to this last list, we are admonished (p. 39) that it would 

 be a good rule to relegate to our Appendix all unconfirmed 

 records of Wade, Smith, and Keogh. This is precisely what 

 we have done in the case of Smith and Keogh (^the instance of
