KEY TO BRITISH BUM. 206 



32. E. macrophyllus W. & N. — St. arcuate-prostrate, usually 

 long and stout, bluntly angular, moderately hairy. Prickles rather 

 few and small, from a large compressed base, falcate or declining. 

 L. usually large, sometimes very large, 5-nate-digitate and pedate. 

 Lts. mostly rather narrow, green and subglabrous above, paler and 

 soft with many short hairs or (when young) grey-felted beneath, 

 with simple distant teeth towards their base, but often compound 

 ones in their upper half and the more prominent frequently recurved ; 



term. It. long-stalked, cordate-ovate or obovate, with long acuminate point. 



Pan. compound, lax, leafy below, sometimes very long, with erect- 

 patent branches and only moderate-sized fl. ; its prickles small, 

 falcate ; its rachis and ped. grey-felted and hairy, and sometimes 

 having a few sessile and very shortly-stalked glands. Sep. triangular- 

 ovate-acuminate, grey-felted, conspicuously reflexed in fl. andfr., often 

 leaf-pointed. Pet. obovate, narrowing considerably to their base, 

 white or pinkish. Fil. white, exceeding green styles. Woods and 



thickets ; widely distributed. 



Variable, but usually well marked by its small prickles, and 



large somewhat greyish Its. and pan. 



b. R. Schlectewlalii (Weihe). — L. thinner, softly hairy (not 

 felted, or only with very close felt) beneath; term. It. obovate-cuneate- 

 cuspidate. Pan much broader and shorter, and fl. larger. Rare, 



I think, in the extreme south. 



c. R. macrophylloides (Genev.). — Like var. b., but with unequal 



on 



considerably glandular. Pet. pink. Wooded hill-side above Tintern, 



Monm. 



d. R. amplificatus (Lees). — Lts. softly hairy only on the veins 

 beneath, as a rule conspicuously narrowed to their base, with large 

 irregular dentate-serrate teeth, and prickly petiolules and midribs; 

 term, obovate-acuminate, subcordate. Pan. somewhat pyramidal, the 

 lower axillary branches often very long, the upper short racemose- 

 corymbose exceeded by the narrow simple floral leaves ; rachis nearly 

 covered with the long bases of the strong prickles. Pet. white or pinkish. 

 Hedges (Midlands and Monm.). 



e. R. glabratus Bab. Lts. shining above, only thinly hairy on veins 

 beneath, and so rather harsh to the touch ; term, subrotund-cordate 

 cuspidate. Pan. with prickles very slender and branches nearly equal, 

 erect or strongly ascending, racemose, with long-peduncled fl. A 

 well-marked plant, as shown me by the Rev. A. Ley in Heref., and 

 as found by Rev. E. F. Linton near Christchurch, Hants. 



f. R. Devoniensis (Focke MS.). — Prickles more unequal (though 

 mostly small), and passing into strong acicles. Lts. obovate, cuspi- 

 date-acuminate. Pan.-branches fascicled, mostly 1-flowered, very 

 unequal, with some shortly -stalked glands, aciculate, strongly ascending. 



Sep. cuspidate-acuminate: Found by Mr. Briggs near Plympton 

 and on border of Dartmoor, S. Devon. I alone am responsible for 

 placing this plant (of which I have a good series in fl. and fr.) 

 under R. macrophyllus.
