Pinus excelsa, Mr. 

 Lambert observes, ap- 

 proaches so near in 

 habit, and in the shape 

 of its cones, to P. Stvo- 

 bus, that, were it not 



1918. P. (S.) excelsa. 



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. 5tr6bus, 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, m the climate of London, appears to be nearly the same as that of P. 

 iS'trobus, and it seems equally hardy.

Synonij/nes. Plfiones. It is so called because 

 it was believed that the Ayacahuite, the abo- 

 riginal name of this species, had originated in 

 P. Pifiones (P. Llavecimo).

Spec. Char., S^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 

 more than 1 ft. long, and 3 in. in 

 iiameter at the base, and tapering 

 towards the point , some much
