64 5. R. PLICATUS. 



found at Bronsted in Jutland. There is a specimen in 

 Herb. Borr., gathered by him at Tilgate in Sussex, and 

 marked as " near R. plicatus, but apparently rooting," which 

 from that sample alone I should have called JR. plicatus ; 

 but as it probably rooted, or at the least was not suberect, 

 it is almost certainly the state of that plant called Ji. fasti- 

 giatus. Dr Bell Salter has written " nitidus " on the 

 label : but the plant has nothing to do with his R. nitidus. 

 There are two specimens from Mertens in Herb. Borr. 

 which are named R. fastigiatus (Weilie) : if suberect they 

 are typical R. plicatus ; if rooting, the form called R. fasti- 

 giatus by Weihe and Nees. On one of them the silky 

 coating of the sepals is much thicker and more persistent 

 than is usual. 



Sometimes strong thorny plants much resemble R. 

 affinis but may be known from it by the following marks: 

 R. j^licatus has a pilose but not felted top to its panicle ; 

 the lateral leaflets of its flowering shoot are dilated or 

 gibbous below ; the sepals are only slightly hairy externally, 

 chiefly at their base and tip, although the felted edge is 

 present in both plants; the stem leaves are hairy on the 

 veins, but never felted beneath; the termincd leaflet is 

 broadest near to its base, not at about its middle as are 

 those of R. affinis, and it is acuminate (or " prolonged," to 

 use the excellent tenii adoj^ted by Mr Woods) rather than 

 cuspidate. 



I have received French specimens of this species from 

 M. Questier with the names R. fastigiatus and R. suberectus, 

 and Genevier gives the former name to specimens of R. plim 

 catv^, R.fissus, and R. suberectus. 



The R. nitidus of Johnston, which he considered to be 

 " veiy well" represented by the plate of R. nitidus in the 

 Rubi Germanici, appears to me to agree exactly with the 

 R. plicatus of the German authors. He considered his
