Dr D. Moore Las sent to me a specimen of R. laciniatas 

 (Willd.), which he received from Hollypark in the county of 

 Dublin ; but he has never seen the plant growing wild, and 

 knows nothing of its histoiy. Apparently it is of garden 

 origin, in common with all those which bear the name of 

 R. laciniatus: for Seringe [DC. Prod. ii. 558) says "Patria 

 ignota;" Willdenow describes it from the Berlin Garden 

 (Hort. Berol. fol. et tab. 89) ; and it is figured by Watson 

 (Dendr. Brit. t. G9) from a nursery garden near London. 

 It was figured as a garden plant by Plukenett in 1691 

 {Fliytogr. t. 108. f. 4). It is not unfrequently found in the 

 gardens of the curious. It is not a state of R. thyrsoideus, 

 as supposed by Willdenow and Weihe and Nees, for it is 

 one of the Sylvatici; it has no apparent relationship to the 

 R. coryUfolius (Sm.), as thought by Wallroth. As it is not 

 known to be a native of Britain, I am not called upon to 

 determine its true place in the Genus nor to describe it here. 

 I have also received specimens from near Truro in Cornwall 

 and Grasmere in Westmoreland. The former is less cer- 

 tainly the R. laciniatus than the latter, which is exactly the 

 garden plant.
