long as its petiolule ; gradually acuminated into long looint and 

 still more gradually narrowed from above the middle to the entire 

 subcuneate base ; with acute or acuminate teeth usually all directed 

 forwards, those of the upper -| or f of the leaflet as a rule con- 

 siderably compound, the lower nearly simple. Stipules narrow 

 linear or linear-lanceolate, densely gland-ciliate. Panicle lax, 

 pyramidal and subracemose above, or more compound straggling 

 and truncate, ivith greater part ultimately ultra-axillary , the top- 

 most bracts elongate narrow and deeply cleft with one or more 

 ovate simple leaves below them ; the lower branches racemose- 

 corymbose, like secondary panicles in strongly developed examples, 

 patent-erect or nearly patent. Bachis and pedicels felted and 

 densely hairy, luitJi very croioded and very unequal but mostly 

 sunken dark stalked glands, an occasional gland-tipped acicle and 

 many rather weak declining or slightly curved prickles but no 

 slender bristles. Sepals attemiate, externally clothed like the rachis, 

 greenish with narrow white margin, loosely reflexed at first, sub- 

 erect or clasping as the fruit forms. Petals pale pink, narrow, 

 distant, remarkably attenuate at both ends. Stamens ultimately 

 pink, soon erect and closing in on the red styles. Carpels more 

 or less hairy. 



On sand and gravel in North-east Hants, South-west Surrey, 

 West Sussex, and West Kent ; frequent and locally abundant. 

 On chalk, Chinnor Hill, Oxford ; a luxuriant form, but I think 

 certainly not distinct from the more eastern type. 



When it is placed beside its nearest allies known to us, the 

 most obviously distinctive characters in this bramble are seen in 

 its singular leaves, as described above, and especially as compared 

 with those of B. rosaceus, in which the leaflets are conspicuously 

 broad and roundish, with very irregular toothing. The armature 

 of B. glareosus, on the other hand, is very like that of B. rosaceus ; 

 in the panicle especially it is nearly or quite identical. But the 

 stem-prickles of B. glareosus are stronger, and nearly confined to 

 the more prominent angles, while the minute pricklets, passing 

 into pointless tubercles, are far more densely packed on the striate 

 faces. It also has a laxer and more ultra- axillary panicle than 

 rosaceus, and much narrower petals. 



The only other plants in our list which might at first sight be 

 mistaken for B. glareosus are my Purchasianus and infecimdus 

 and B. pallidus Wh. & N. But B. pallidus may without much diffi- 

 culty be separated from it by its distinctly more radulan armature, 

 its numerous large 5-nate leaves, and conspicuously ovate leaflets 

 less narrowed below their middle to a rounded cordate base, with 

 coarser irregular serration, and its white petals ; while Purchasi- 

 anus and infecundus differ conspicuously enough in many of their 

 characters. 



Thus iiifecundus may be readily recognized by its still deeper 

 and more generally diffused red coloration, its nearly patent long 

 acicular prickles, thick soft yellowish-green and chiefly 5-nate 

 leaves, and large nearly oval terminal leaflet with principal teeth 

 patent or subpatent ; together with the more unequal gland-tipped
