ON THE RUBI AND ROS^ OF THE CHANNEL ISLANDS. 89 



than is found in that species, occurs in considerable quantity on the 

 north coast of Jersey, between the churches of St. Mary and St. 

 Lawrence, as well as in Waterworks Valley and in St. Aubin's Bay. 

 But this remains unnamed at present. 



No members of the groups Koelderiani and Bellardiani were 

 observed in the islands. 



CiESII. 



R. dumetorum Wh. & N., ferox Weihe. Generally distributed, 

 but variable, as in Britain. Brittany : La Garaye, with white 

 petals, as usually in England. Normandy: Near Coutances, with 

 pink petals, as in Germany ; Lison. 



Var. diversifolius (Lindl.). Sark : Banks near the Dixcart 

 Hotel, a weak form. 



Var. tuherculatus Bab. Jersey : Between Les Marais Railway 

 Station and Fauvic, in some quantity. 



B. Gorylif alius Sm. (sp. coll.). Guernsey : Cobo ; near Vale 

 Church. Sark. Jersey : Gorey ; Anne Port ; Grosnez. 



a. suhlustris (Lees). Jersey : Bouley Bay ; the type. 



b. cyclophyllus Lindeb. Guernsey : Fairly frequent. Jersey : 

 Bouley Bay. 



B. Balfourianus Blox. Sark : Very characteristic, though weaker 

 than the average plant. Jersey : Head of the Val des Vaux ; an 

 exceedingly luxuriant form. 



B. caesiiis h. Guernsey: Rather frequent. Jersey: Les Marais; 

 Corbiere. Not observed in great quantity. Normandy : Very 

 general and variable. 



B. laciniatus Willd. Guernsey : Petit Bot Bay ; not quite the 

 usual form. 



The only hybrid Rubi seen in the Channel Islands, as to the 

 origin of which there seemed little room for doubt, are the fol- 

 lowing : — B. rhamnifoUiis x leiwostachys. Jersey : Rozel. — jR. riisti- 

 canus X tuherculatus. Jersey : Les Marais. 



A very brief notice of other Rubi observed in Britany or 

 Normandy, though not in the Channel Islands, may be of interest 

 here. 



B. suberectus Anders. Brittany: In the valley of the R. Ranee, 

 near Dinan. A nearly unarmed but well-marked form of this 

 species. 



B. erythrinus Genev. Brittany: La Garaye and elsewhere in 

 the Dinan neighbourhood ; common. Clearly the same plant as 

 the one we are naming B. erythrinus in England, though showing 

 a tendency to a broader and so more nearly subrotund terminal 

 leaflet. At La Garaye occurs in some quantity what seems to be 

 B. erythrinus X micans, B. micans being abundant there also. The 

 apparent absence of Bi. erythrinus from the Channel Islands is 

 remarkable. 



B. oigoclados Muell. & Lefv. Apparently a form of this. Brit- 

 tany : Near Dinan. Normandy : Near Coutances.
