86 ON THE RUBI AND ROSZE OF THE CHANNEL ISLANDS. 



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. 



SUBEEECTI. 



Rubus ajfi/nis 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 Journ. Bot. 1894, 42. The only sub 

 erect bramble seen by us in the islands. 



Rhamnifolii. 



Pi. iiicurvatus Bab. Jersey : St. Aubin's Bay. Not the typical 

 ]3lant, but a form with leaflets thinner, more roundish, and with 

 paler felt beneath, which is found in some quantity in at least three 

 S. England counties. 



R. rhamnifolius Wh. & N. (sp. coll.). Guernsey: Fermain 

 and Petit Bot Bays ; very near the ordinary British form {R. cardio- 

 ])lujllus Lefv. & 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. cardio- 

 phglkis, ^^hicli (unlike the rare typical R. rhamnifolins) seems dispersed 

 throughout Western Europe, and is one of our commonest and most 

 constant forms. 



it. imlcherrimus Neum. Guernsey : Rather common, especially 

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

 Trinity Hill ; Waterworks Valley. 



Fi. 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 occurs in Sark, and at Petit Bot 

 Bay, Guernsey (unknown thus far in Britain), with terminal leaflet 

 subrotund and strongly cordate. 



Pi. rhombifolms Weihe. Guernsey: Fermain Bay. 



R. argentatus P. J. Muell. Guernsey : One of the most abundant 

 brambles in the island ; generally distributed, but variable. Jersey : 

 Fauvic ; Waterworks Valley ; Pont Marquet. Abundant in places, 

 but apparently not so general as in Guernsey. Brittany : La 

 Garaye, near Dinan. Normandy : Hill above La Bouille. 



Var. rohustus (P. J. Muell.). Here, rather than under the type, 

 appear to belong forms that occur at Cobo, near St. Martin's 

 Church, Fermain Bay, and St. Sampson's, in Guernsey, and near 

 Coutances, in Normandy ; but the range of variation is considerable
