rather abundant. This is the fourth Irish county in which this 

 species has now been found.

 subsp. rachdoides), Fraef/er ! 



Subsp. vestitiformis Rogers. *38. Anacloan, in one lane, several

 Lough Gilly, Dmce ! Quite typical and in great quantity at 

 Scarva and by the Dublin Road, Newry. "38. Aghaderg ; Ana- 

 cloan. Locally abundant. 



R. Drejeri G. Jensen. "39. Glynn ; hillside by limestone 

 quarries. Typical, but seen only in small quantity. 



Subsp. hibernicus Rogers. '■■37. Scarva, very abundant ; near 

 Newry, in no great quantity. 38. Common at Aghaderg and 

 Anacloan, over a large area; near Banbridge ; Saintfield, Waddell \ 

 In wood-borders and hedges, with the next. 



R. dunensis, sp. (or subsp.) nov. Stem, bluntly angled, con- 

 siderahhj hairy, with scattered unequal armature varying very greatly 

 in amount, but often quite Koehlerian in character. Prickles mostly 

 slender from stout base and rather short. Larger acicles and bristles 

 often gland-tipped. Stalked glands many, very unequal. Leaves 

 very broad, al^s^ys yellowish, conspicuously concave, opaque and thinly 

 strigose above, at first softly hairy beneath, icitJi somewhat sinuate 

 sharply pointed compound teeth. Terminal leaflet roundish-oval, ivith 

 long acuminate point and cordate base ; intermediate exceptionally long 

 and usually overlapping the subsessile basal ones. Panicle with short 

 close pyramidal top and two or three distant lower racemose branches, 

 remarkably brown in upper half. Rachis slightly flexuose, with 

 patent brownish hair hiding the crowded short-stalked glands ; 

 gland-tipped acicles exceeding hair rather few ; prickles weak, 

 declining or patent. Flowers cup-shaped. Sepals very glandular, 

 brownish, soon rising and often remaining erect. Petals narrow, 

 faintly pinkish or white. Stamens erect, exceeding styles. Carpels 

 glabrous. Flowers early and fruits abundantly. Fruit excellent. 

 One of the few earlier flowering and most abundant brambles in 

 West Down and the adjoining parts of Armagh. Received also 

 from Saintfield, East Down. Strongly recalls B. Drejeri and its 

 two subspecies, but keeps quite distinct. 



This is included under subsp. hibernicus in Handbk. Brit. Bubi, 

 p. 63 (as a strong form) ; but, when constantly growing with it 

 under like conditions, it flowers a fortnight earlier, and can always 

 be distinguished from it at some distance by its yellow tint, concave 

 leaves, and peculiar brownish panicle close-branched above and 

 very lax below. The sinuation of the leaf-toothing is usually less
