11. R. LATIFOLIUS. 95 



Flowering shoot long, surrounded at its base by short 

 scales ashy with silky pubescence, angular, gi'een, nearly 

 glabrous. Prickles few, short, weak, from long bases, 

 slender, declining, yellow tinged with purple. Leaves ter- 

 nate. Leaflets pilose on both sides but chiefly beneath, 

 nearly equal, ovate, acute, deeply and doubly serrate, lower 

 ones often strongly lobed on the outer edge below; petioles 

 with very few slender declining or deflexed prickles; midrib 

 unarnied or with small prickles; stipules linear-lanceolate. 

 Panicle short, leafy below, pilose ; the upper part and 

 pedicels felted, pilose, and with a few short sunken setae or 

 subsessile glands; prickles short, declining, slender, yellow; 

 branches short, ascending, few-flowered, corymbose; bracts 

 trifid with narrow lanceolate segments. Sepals ovate-acu- 

 minate, felted on both sides, whitish within, rather green 

 and pilose externally, reflexed loosely from the fruit. Petals 

 shortly ovate, clawed. Primordial fruit apparently hardly 

 more than hemispherical. The flowers and fruit require 

 more careful examination. 



The leaflets have very large acute teeth, almost amount- 

 ing to lobes on both of my Scottish plants (but on that from 

 ISIonmouthshire, although they are coarsely and doubly- 

 dentate, the large double teeth are not so conspicuous); the 

 teeth or lobes are themselves irregularly and acutely toothed, 

 and are divided from each other by very acute angles. The 

 leaves are truly dentate, although the teeth are all slightly- 

 directed forwards; none of the teeth are patent nor divari- 

 cate. The Monmouthshire specimen, for I unfortunately 

 gathered only one, has rather stronger prickles, its terminal 

 leaflets roundly cordate-obovate and cuspidate-acuminate, its 

 basal leaflets very shortly stalked ; but in other respects it 

 accords with the Scottish plants. 



In my Synopsis I placed this plant doubtfully under P. 

 Salteri. to which I am now convinced that it has no relation-
