292 RUBI AND ROS^ OF THE CHANNEL ISLANDS. 



We saw in all about thirty distinct forms, as named in 

 the following notes, besides five or six obscure ones which may 

 prove too strictly local to require naming. These last, with 

 one exception in Guernsey and one in Sark, occurred in 

 Jersey, where, as might be expected, the close alliance with 

 British forms is less marked than it is in the more western 

 islands. In all the islands, however, the vast majority of the 

 brambles seen are practically identical with our British forms. 



From Jersey we crossed to Brittany, and, after a few 

 days at Dinan, made our way through Normandy to Dieppe 

 and Boulogne. Our opportunities for studying the Rubi and 

 Rosas of north-west France did not prove good ; but we have 

 been encouraged to believe that a very brief reference to the 

 French species seen by us, in connection with the Channel 

 Islands records, will not be thought out of place in this paper. 

 No localities are given for France or for the islands but those 

 in which we saw the plants in question growing ; except in 

 the case of two Sark rose localities of Mr. Derrick's 

 furnishing, of which we saw dried specimens. As on so 

 many previous occasions, we are greatly indebted to 

 Dr. Focke for his ready and valuable help in our efforts to 

 name some of the obscurer Rubi. 



RUBI. 



SUBERECTI. 



RubUS afflnis, Wh. § N., var. Briggsianus, Rogers. Guernsey : in several 

 places, especially at St. Sampson's, Petit Bot Bay and Cobo. Jersey : in 

 one spot near the Waterworks Valley. Exactly the British form described 

 in Journal of Botany, 1894, 42. The only sub-erect bramble seen by us in 

 the islands. 



RHAMNIFOLII. 



R. inCUTVatUS, Bab. Jersey : St. Aubin's Bay. Not the typical plant, but 

 a form with leaflets thinner, more roundish, and with paler felt beneath, 

 which is found in some quantity in at least three south England counties. 



R. rhamnifolius, Wh. § N. (sp. coll.). Guernsey: Fermain and Petit Bot 

 Bays ; very near the ordinary British form (R. cardiophyllus, Lefv. and 

 Muell.), if not identical with it. Jersey : Rozel and Pont Marquet ; small 

 leaved forms. Normandy : Bonsecours Hill, near Rouen, in plenty ; just 

 the plant we are calling R. cardiophyllus, which (unlike the rare typical 

 R. rhamnifolius) seems dispersed throughout Western Europe, and is one 

 of our commonest and most constant forms. 



R. puleherrimus, JVeum. Guernsey : Rather common, especially about 

 St. Peter-Port, Petit Bot Bay, and near Vale Castle. Jersey: Trinity 

 Hill ; Waterworks Valley. 



R. dumnoniensis, Bab. Guernsey : Petit Bot Bay, in good quantity ; and 

 in one or two other localities. Sark ; Near Dixcart Hotel, in plenty. 

 Jersey : One of the most frequent brambles. Especially abundant at 

 Gorey Bay, Val des Vaux, Waterworks Valley, and Pont Marquet. 

 Usually identical with our luxuriant British form ; but a second form
