220 32. R. DIVERSIFOLIUS. 



neniorosus ad var. a ferocem accedens, si calyces fructus sint 

 erecti" by Nees, wliich are mentioned in Leigliton's Flora 

 (238), were referred by Borrer to B. dumetorum and recog- 

 nised by him as the R. diversifolius of Lindley's latter opinion. 

 They certainly are the true R. diversifolius as ultimately un- 

 derstood by Lindley, and now recognised as such by me. Also 

 other specimens sent by Leighton to Borrer and Lindley, and 

 returned named by them, seem to belong to R. diversifolius. 

 They are marked Nos. 25 and 2Q, and considered as "un- 

 doubtedly R. nemorosus'^ by Leighton, "i?. Radula'' by 

 Lindley, and " R. ccesius'^ by Borrer. I believe them to be 

 states of R. diversifolius with fewer prickles than usual, and 

 smaller and less compound panicles ; they are probably the 

 shoots of young plants. Another specimen, No. 16, was 

 considered by Nees von Esenbech to be "^. dumetorum /? 

 nemorosusy Leighton believed it to be the same as Nos. 

 25 and 26, but I think that it belongs to the RadulcB. Its 

 stems are young and not in a satisfactory state for exami- 

 nation, but its leaves and panicle seem to prove that it is 

 a state of R. Hystrix. 



The R. Schleicheri (Leight.) appears to be a state of this 

 species. It agrees far more nearly with R. diversifolius 

 than with any other of our plants. The chief differences 

 seem to be that the panicle is usually furnished with longer 

 and more spreading branches, the leaves are nearly or quite 

 devoid of felt, being only densely hairy on the veins be- 

 neath, and the terminal leaflet is rather longer in proportion 

 to its breadth. I have no doubt of its being rightly placed 

 amongst the Koehleriayii ; although it often closely resembles 

 R, tuherculatus, which belongs to the Ccesii. R. tuherculatus 

 has a decided bloom, and very inconspicuous, short and 

 nearly equal acicnli and setse upon the stem, prickles spring- 

 ing from large oval dejjressed tubercles, a terminal leaflet, 

 which is usually much broader and more cordate at the
