ON THE KUBI AND KOS^ OF THE CHANNEL ISLANDS. 87 



and somewhat bewildering. A very handsome plant occnrring in 

 good quantity in Waterworks Valley, Jersey, Dr. Focke thinks is his 

 R. niacrostemon, though it differs from the German plant in its more 

 luxuriant and diffuse panicle. It seems to go off from R. rohmtus 

 towards R. danicus Focke, while on the whole best placed perhaps 

 in the Discolor es group. 



DiSCOLOKES. 



R. rnsticanus Merc. Very common in the islands and on the 

 French coast opposite them, and at least as variable as in England. 



SiLVATICI. 



R. macropliyUus Wh. & N. Jersey : Deep lane, Bouley Bay ; a 

 shade form. Brittany : La Garaye, near Dinan. Normandy : 

 Moulineux, wood border. 



Var. macropJujlloides Genev. Guernsey, rather frequent : St. 

 Sampson's ; St. Martin's ; Fermain Bay. Sark : Very fine and 

 remarkably abundant, apparently more so than all the other 

 brambles in the island put together. Dr. Focke considers this 

 "very near R. Schlecht end alii.'' It seems best to regard it as a 

 strong and highly glandular form of that variety. In England 

 thus far found only in Monmouthshire and South Devon with 

 certainty, though a rather similar form has been gathered in West 

 Gloucestershire and Salop. 



R. Qitestierii Lefv. & Muell. Jersey : Val des Vaux, the locality 

 in which this species was discovered by the Eev. Augustin Ley 

 several years ago. Elsewhere in the islands we searched for it in 

 vain, though it is probably not confined to this one Jersey locality, 

 as it seems remarkably abundant on the French coast. Brittany : 

 La Garaye and near Lehon, in plenty. Normandy : Coutances 

 and elsewhere ; Moulineux, abundant. 



R. Rprengelii Weihe. Guernsey : Fermain Bay. Jersey : Anne 

 Port and Bouley Bay. Quite typical in both islands, 



R. micans Gren. & Godr. Jersey : Gorey and Anne Port. 

 Brittany : La Garaye, abundant. Normandy : Certainly one of 

 the commonest brambles, and usually identical with Genevier's 

 own specimens of his adscitus and our typical S.W. England form. 



R. leiicostachys Schleich. As an aggregate species abundant in 

 Guernsey and Jersey, though usually in an untypical form. Seen 

 also on Sark. Brittany : What seems a form of this at La Garaye. 

 Normandy : Moulineux. 



Var. angustifolius Rogers. Guernsey : Fermain Bay. Jersey : 

 Pont Marquet ; Anne Port ; Rozel. Normandy : Moulineux. 

 Nearly allied to R. leucostachys, and considered by Dr. Focke 

 to be also "near R. argyronthiis Boul. & Luc." are plants which 

 occur in some quantity at Norgeots, Guernsey, and at Bouley Bay, 

 Jersey ; but these demand further study. 



R. ADENANTHus Boul. & Gillot. Dr. Focke has thus named a 

 very handsome plant which grows in some quantity in Gorey Bay, 

 Jersey. In general appearance it seems intermediate between 

 R. leucostachys and R. radula Weihe, while also somewhat recalling
