Botanical Society of London. 



Oct. 2, 1846.— Edward Doubleday, Esq., Vice President, F.L.S., 

 in the Chair. The Secretary announced that British Plants had been 

 received from Dr. Dickie, Mr. R. J. Mann, Mr. Samuel Hailstone, 

 Mr. G. H. K. Thwaites, Mr. H. O. Stephens, Mr. J. Roby, and Mr. G. 

 Lawson. The Royal Botanic Society presented two dried examples 

 of the Orobanche sent to that Society as probably the Orobauche luco- 

 rum {Brautt), but which cannot be certainly identified with the de- 

 scription of that species in the Synopsis of Koch. Indeed it appeared 

 to some of the members, that the two specimens were those of diffe- 

 rent species ; one being very similar to Orobanche major, and the 

 other equally similar to Orobanche elatior. It seems highly probable, 

 therefore, that some confusion of species has occurred, which may 

 have increased the difficulty of determining the plants satisfactorily, 

 and may have been instrumental in giving rise to the different views 

 expressed by those botanists who had previously examined the plants 

 in their living state.

Occurrence of Erica ciliaris in the County Galway, West of 

 Ireland. By the Editok. 



We learn that Mr. Bergin has had the good fortune to add this beau- 

 tiful species to the already extensive list of Irish heaths. Its locality 

 is in the county Galway, and not far from Clifton, indeed, almost ex- 

 actly the same as that previously recorded for Erica Mackaiana ; a 

 circumstance which seems to throw an additional doubt over the dis- 

 tinctness of that species, by suggesting the possibility of its being 

 a hybrid between E. ciliaris and E. Tetralix. 



As to the accuracy of name in Mr. Bergin's heath we have no doubt, 

 since our esteemed correspondent, Mr. Moore, a botanist not likely to 

 be deceived, has received specimens, and unhesitatingly pronounces 

 them to be Erica ciliaris. 



We have long been expecting a communication on this subject, but 

 do not like longer to delay announcing so important a discovery.
