Pinus excélsa, Mr. 
Lambert observes, ap- 
eae so near in 
habit, and in the shape 
of its cones, to P. Stro- 
bus, that, were it not 
1917. P. (S.) excélsa. 
for the simple, round, 
membranaceous crest of 
the anthers, it would be 
almost impossible to dis- 
tinguish them specifi- 
cally. The leaves are 
‘onger than in P. Strobus, and the cones are thicker. Dr. Royle makes a 
similar remark as to the resemblance of this tree to P. Strobus, and adds 
“that it is remarkable for its drooping branches, whence it is frequently called 
the ‘ weeping fir, by travellers in the Himalayas.” The rate of growth of this 
tree, in the climate of London, appears to be nearly the same as that of P. 
Strobus, and it seems equally hardy.

Spec. Char., §c. Leaves in fives, on 
small spur-like protuberances, which, 
when very close together, make the 
twig look stunted and very crooked. 
Leaves from 3 in. to 4 in. long, and 
about + of a line broad; flat on the 
back, but with a sharp projecting 
keel-like midrib, and two furrows. 
The leaves are whitish when young, 
with sharp thickened small teeth, 
not very close together, in the mar- 
gin towards the points. Cones
