Pinus excelsa, Mr. 

 Lambert observes, ap- 

 proaches so near in 

 nabit, and in the shape 

 of its cones, to P. Strb- 

 bus, that, were it not

for the simple, round, 

 membranaceous crest of 

 the anthers, it would be 

 almost impossible to dis- 

 tinguish them specifi- 

 cally. The leaves are 

 longer than in P. Strobus, and the cones are thicker. Dr. Royle makes a 

 similar remark as to the resemblance of this tree to P. ^trobus, 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. 

 tftrobus, and it seems equally hardy.

 small spur-like protuberances, which, 

 when very close together, make the

 The leaves are whitish when young, 

 with sharp thickened small teeth, 

 not very close together, in the mar- 

 gin towards the points. Cones
