In exposed places an erect shrub 3 or 4 feet high, but in 

 hedges drawn ont and slightly arching. Prickles less crowded 

 than in involuta, but running gradually down into setaceous 

 acieuli in the same way. Main prickles stouter than in the 

 last, decidedly curved, the scar 5-G lines deep. Leaves of the 

 barren shoot 3-4 inches long, the terminal leaflet broad-oblong or 

 ovate-oblong, 9-12 lines long by three-fourths as broad, the upper 

 surface a slightly glaucous green, naked or inconspicuously hairy 

 on the midrib, the lower surface thinly hairy on the veins, not at 

 all glandular ; the serration moderately sharp and open, the teeth 

 simple or casually gashed, the petiole pubescent, with three or 

 four slender hooked aciculi and an occasional gland. Stipules 

 scarcely at all hairy on the back, with deltoid gland-ciliated 

 auricles. Flowers generally 1 to 3, but sometimes up to a dozen, 

 the peduncle 4-6 lines long, quite naked, the globose or broad- 

 ovate calyx-tube the same, the segments 8-9 lines long, quite 

 naked on the back, the main ones copiously leaf-pointed and 

 pinnate. Corolla pale-pink, 15-18 lines across when expanded. 

 Styles densely hairy. Sepals ascending after the petals fall, but 

 not fully persistent. Truit roundish, about half an inch long 

 and thick, crowned with a decided disk, not ripening till Oc- 

 tober. The form with hairy leaves occurs in Derry and Down 

 {Templetonl, Dickie^ Moorel, &c,), and in England, in Cumber- 

 land {Borrer^?) and Cheshire (Webb I), A form (var. glalray 

 Baker, Review, p. 11, Exsic. p. 4) with sharper teeth and leaves 

 quite naked has been gathered in Sutherlandshire (Healam 

 Ferry, near Loch Eriboll) and in Durham (near Witton-le- 

 Wear) by Prof. 01i\'er, in Cumberland by Mr. Borrer, in North 

 Yorkshire by Mr. Mudd and myself, in Cheshire by Mr. Webb 

 and others, and in Surrey by Mr. E. Castle ; and Dr. Moore lias 

 found another glabrous form with larger nearly round leaves and
