LXXVII. CON’ FERE: PINUS. 997 
rated. Cone (see jig. 1868.) from 
5in. to S5iin. long, and 24 in. to ¢ 
23 in. broad; scale, according to \ 
‘Mr. Lambert’s plate (see fig. 1867.), iN 
from 14 in. to 2in. in length. Seed, 
without the wing, 2in. long; with 
the wing, 13in. Cotyledons, ac- 
cording to Lawson, about 12. A 
large tree. Himalayas. Introduced 
in 1807, and requiring protection 
in England. 
P. longifolia is a native of Nepal, 
on the mountains ; and also of the 
lower and warmer parts of India, 
where the tree is cultivated on ac- 
count of its beautiful foliage and 
graceful habit of growth, but where it 
never attains the same magnitude as 1867. P. longifolia. 
on the Himalayan Mountains. It was 
introduced into Britain in 1801, and for u long time was treated as a green- 
house plant ; it is now 
found to stand the open 
air, but not without 
protection during win- 
ter. The largest tree 
in England is believed 
to be that at Drop- 
more. It was, in 1837, 
nearly 12 ft. high ; but 
it is covered every win- 
ter with a portable roof 
of fern, enclosed in 
mats, and supported by 
a wooden frame; the 
sides being closed in 
with the same mate- 
rials, but with two 
doors opposite each | 
other, to open on fine | 
days, to promote ven- 
tilation. Mr. Lawson 
suggests that the ten- 
derness which is appa- 
rent in some individuals 
of this species may 
possibly arise from the 
seed from which they 
were raised having been 
produced by trees grow- 
ing in the warm valleys 
of Nepal; and that, ; 
“ by procuring seed 
from trees at the high- 
est elevation at which 
they are found to exist, 
plants might be raised 
sufficiently hardy to 
stand the climate of 
Britain.”
