original manuscript, which calls for a correction. " Juglans Hindsii X 

 nigra, Royal Walnut" does not occur in Massachusetts; it is like the 

 Paradox Walnut a cross of Burbank's and originated in California. The 

 Massachusetts trees mentioned belong to J, cinerea X regia = J. qua- 

 drangulata B^ehd. {J. intermedia quandrangnlata Carr.). To the hybrids

media Carr. which was first observed in Europe and to which probably 

 the "James River Hybrid" belongs.

This variety differs from the type in the 3-foliate, not 3-5-parted, 

 leaves and in the densely villose calyx neither bristly nor glandular. 



Though I have no doubt that K Henryi and R. bambusarum arc con- 

 specific, I prefer to keep the latter form distinct at least as a variety, as 

 there arc hardly any transitions between the two. In Plantae Wilsonianae 

 (i. 49 (1911]) where Focke refers iJ. bambusarum as a synonym to R. 

 Henryi^ he states that ternate and simply trifid leaves occur on the ; 

 branch, but as the specimens (Wilson No. 48) show the trifid or simple 



lanceolate leaves occur only just below the inflorescence; and it is the 

 case in almost all compound-leaved Rubus, that the leaves below the 

 inflorescence are apt to be simple. Otherwise the specimens before me 

 show either the simple trifid leaves of R. Ilenryi as in Wilson's No. 76 and 

 in his No. 996 of the Veitch Expedition and or the ternate leaves of the 

 var. bambusarum as in Wilson's No. 48 and in his No. 786 of the Veitch 

 Expedition. The same is true of the cultivated plants of both forms,

now generally known as X. racemosum Miquel was first described by 



L 



Loureiro as Croton congestum (Fl. Cochinch. 582 [1790]) which made 

 necessary the new specific combination X. congestum Merrill, and this in 

 turn involves the new varietal combination proposed above.
