BOTANICAL SOCIETY OF LONDON. 



Friday, October 6th, 1848. — J. Reynolds, Esq., Treasurer, in the 

 chair. 



Mr. G. S. Gibson exhibited specimens of Melilotus arvensis 

 ( Wallr.), collected in the neighbourhood of Saffron Walden, Essex, 

 which appear to be an identical species with M. Petitpierreana 

 (Willd.), except that the latter was founded on a white-flowered va-

 label the yellow-flowered states by the name of Petitpierreana. Mr. 

 Gibson explained the distinctions between the new species and M. 

 officinalis, with which the yellow flowers might cause it to be con- 

 fused, but in technical characters it is otherwise more allied to M. 

 alba {Des.), and from which the white-flowered variety of M. Petit- 

 pierreana will with difficulty be distinguished if it should be found 

 in England. 



Mr. Thomas Moore communicated a paper, being "Notes on two 

 varieties of Pteris aquilina." — G. E. D.

 and I therefore beg leave to express a hope that we may have as lit- 

 tle ill humour on the subject as possible, however great may be the 

 difference of opinion that may exist thereon. Having expressed this 

 hope, allow me next to mention that Euphorbia salicifolia is natural- 

 ized with us here, although it is not so in botanical books ; I say
