based short prickles, and some acicles and stalked glands in the 

 lower part ; the large prickles subequal, nearly confined to angles, 

 strongly declining or even dejiexed, and some falcate, with long points 

 from much-dilated and compressed base. L. 5-nate-pedate or 

 digitate, concave. Lts. unevenly mucronate- serrate (the upper teeth 

 coarse and occasionally almost lobate, but sbarp-pointed), bright 

 green and with scattered hairs above, much paler beneath, and 

 even thinly felted when young ; term, variable, but usually broadest 

 a little above the middle, strongly acuminate, cordate or subcordate ; 



interna, large, often gibbous below ; bas. very shortly stalked ; 



petioles, petiolules and midribs strongly armed with recurved prickles'. 

 Pan. with erect-patent pseudo-umbellate branches below; the ultra- 

 axillary part rather broad, sometimes with dense interlacing 

 branches exceeding the floral 1. ; the rachis moderately hairy and 

 glandular, very strongly armed like the st. ; the ped. with numerous 

 acicles and slender prickles. Sep. usually prickly at base, grey- 

 green, with narrow white margin, patent after pet. fall. Pet. rather 



small, obovate or elliptic, pinkish. Stain, and styles about equal, 

 sometimes reddening below. Hedges and bushy places (York' 

 Derb., Surr., and?Dev.). v 



When seen at a little distance, recalling R. plicatus and R. ery- 

 thnnus in habit and colouring. I have a specimen of Bloxam's, 

 labelled « R. infestus W. & N. Near Coventry," which appears to me 

 to be this plant.

 Di. _Uocke numbers as good bramble "species." R. egregius seems 

 (both from his descriptions and specimens) to be near R. mucronatus ; 

 but it has weak declining prickles, a pan. longer and narrower

beneath when young, and Its. rather cuspidate-acuminate than 

 mucronate, and narrowing considerably to their base. The prickles 

 ot h. SchUckumi are apparently much stronger, its 1. 3-nate or 

 5-nate-pedate and white-felted beneath, and Its. long-pointed and 

 somewhat biserrate, its pan. leafless above, and pet. long and pink. 

 YVirtgen s specimens at Cambridge have also a remarkably purplish 

 st. and pan.-rachis. Both species have their sep. reflexed in fl. and 

 tr. R. chlorothyrsos is more glandular and aciculate than either of 

 these It also has very strong prickles. In other respects it is 

 near h. sUvattem W. & N. L. green on both sides. Pan. long, 

 narrow, lax, often (and especially in shade) leafy to the top with 

 many simple 1. Sep. patent in young fr. Stam. scarcely equalling
