BOTANICAL SOCIETY OF LONDON. 



Sept. 4, 1846. — Edward Doubleday, Esq., F.L.S., V.P., in the 

 chair. 



Donations to the library were announced from Dr. Cooke, Dr. 

 Ayres, Dr. Palmer, Mr. G. Cooper, Mr. J. Reynolds, Mr. H. W. 

 Martin, Mr. J. Freeman, Mr. J. Rich and Mr. G. Rich. British 

 plants have been received from Mr. S. P. Woodward, Mr. Charles 

 Prentice, Mr. Watkins, Mr. George Lawson, and Mr. J. Roby. Mr. 

 Williamson, of Kew Gardens, presented specimens of an Orobanche, 

 collected by him near Epsom, Surrey, and suggested to be Oro- 

 banche lucorum (of Brauu), but perhaps rather an identical species 

 with the Orobanche elatior (of Sutton). Its occurrence in clover 

 fields, in which the specimens were collected by Mr. Williamson, is 

 also in favour of this view. The specimens differ from the character 

 given to Orobanche lucorum, in Koch's Synopsis, by having the se- 

 pals shorter than the tube of the corolla ; but in other respects the 

 dried specimens do not exhibit any decided difference from the cha- 

 racters of Orobanche lucorum, though corresponding as well with 

 those of Orobanche elatior.
