ARTHUR BENNETT, F.L.S., 



Croydon. 



With respect to the British species of the genus Orobanche , it 

 may be well to put on record the plants on which they have 

 been found. 



Orobanche rubra Sm. is recorded principally on TJiymiis, by 

 Mr. A. G. More on Festuca rubra, and by Dr. G. Beck on 

 Clijiopodhim vulgare, Origanum vulgare, and Prunella vul- 

 garis. 



Orobanche caryophyllacea Sm. On Galium molhigo ! , 

 Aparine, boreale, erectum, and vcrum ! ; Lotus corniculatus ! , 

 Rnbus fruticosus (Syme), and Beck gives Achillea millefolia, 

 Ligustruin, Lychnis dioica, etc. 



Orobanche elatoir Sutton. On Carduus crispus ! , LCnautia 

 arveiisis ! , Centaurea nigra and Scabiosa ! , and Beck gives 

 Onobryc/iis saliva. 



Orobanche Picridis F.W.Schultz. On Picris\ and Daucus 

 Carola ! 



Orobanche Heder^ Duby. On Hedera Llelix ! 



Orobanche amethystea Thuil. Daucus Carola ! , Ononis 

 arvensis ! , Eryngitim maritimiun (Syme), Planlago Coronopus

 repens ! , pratense ! , Ononis ai^ensis ! , Lotus corniculatus ! , 

 Nepeta Glecho?na ! , Carduus crispus ! , C. nutans (Henslow),

 Leontodon autmnnalis ! , and 14 other species are g-iven by 

 Beck in his Monogfraph. 



Orobanche major Sm. non. L. According to Dr. Beck O. 

 major Smith = O. Rapum Genislce Thuill, and O. major L. 

 is O. elatior Sutton. 



Orobanche Rapum Genista Thuill. Sarothamuus vulgaris ! ,

Orobanche purpurea Jacq. [O. caerulea Vill.). On Achillea 

 millefoliimi ! , and Beck adds Artemesia canipestris and vul- 

 garis, Cirsium acaiile. 



I certainly do not think our list of British species is yet 

 complete. I have two or three in my herbarium that I believe 

 are new sp. to Britain, but dried they are very difficult to 

 determine.
