Coniferae included in the report being supplied by 
Dr. Greville and Professor Balfour. This report appears 
to be rarely met with, and has been little consulted, for the 
new species with which it deals have been by some 
attributed to Murray, by others partly to Balfour and 
partly to Jeffrey. -The coloured plate representing P. 
Jeffreyi bears the signature of Dr. Greville. ‘Opinions are 
divided as to whether this tree deserves specific rank ; there 
is no difficulty in distinguishing the form now described, 
the account of which is based exclusively on material from 
a tree in cultivation in the Arboretum at Kew, from culti- 
vated examples of P. ponderosa, but it is stated that inter- 
mediate wild forms have been met with. 
Opinions appear to be similarly divided as to the relative 
ornamental value of P. Jeffreyi and P. ponderosa, Sir 
Joseph Hooker, in the passage referred to above, describes 
it, as seen by him in a wild state, as inferior to P. ponderosa 
and as by no means a handsome tree; his figure bears out. 
_ this judgment. Yet, as met with in cultivation, the longer 
leaves and the larger cones serve to render P. Jeffreyt 
perhaps the more striking of the two. Though neither of 
these near allies can be considered among the handsomest 
of Pines, in habit they are both notable in the parks and 
gardens of this country for their tall, stately, column-like 
trunks—as a rule, perhaps, too thinly set with branches to 
- make them perfect specimen trees ; for their deeply fissured, 
rugged bark; for their long rigid leaves arranged in a 
brush-like cluster on the terminal portion of each year’s 
growth ; and, more especially as regards P. Jeffreyi, for the 
fine, handsomely coloured cones. Young trees are. best 
reared from imported seed. 
Descriprion.—Tree, the one here figured about 40 ft.
