best use may be said to have been made of the 
species already possessed. The Rhododendron ar- 
boreum, a tender species — the finest possessed by 
this country previously to those above mentioned, 
has been most extensively hybridised with more 
hardy species. From the offspring so obtained, 
other crossed varieties have been propagated, and 
this through a series of generations ; so that the 
parentage of many of the finest Rhododendrons 
now in our gardens can neither be told by their 
originators, nor recognized by the botanist. 
The fine specimen which we have here figured 
was thus raised by Mr. Jackman, nurseryman, of 
Woking, after whom it is named. Mr. Jackman 
says, “Some time since, I hybridised some hybrid 
varieties of Rhododendron Catawbiense, with fine 
scarlet varieties, and the plant in question was 
raised from that cross.” The scarlet variety alluded 
to had probably arisen from various crossings, de- 
riving its colour from arboreum. Mr. Jackman 
obligingly sent us one of these plants in December, 
1849; which was immediately planted out. Its 
habit is good, and it flowered in perfection. This 
year again every shoot has its flower-bud, corrobor- 
ative of the originator’s opinion that it is the best 
he ever possessed for constancy of flowering, and it 
certainly is a handsome variety. 
We have been favoured by Mr. Moore, nursery- 
man, of Perry Bar, with the inspection of a drawing 
of another hybrid Rhododendron, of very similar 
character to Mr. Jackman’s, but possessing some- 
what less colour. Every admirer of such shrubs 
should possess both of them.
