22 PINES 
It is so called for the obvious reason that its twigs 
snap upon the slightest provocation. 
This Willow, then, may be said to represent the 
extreme party of the inflexibles, while the Pine in 
subject may be regarded as representing extremists 
of the opposition and the most flexible examples 
of tree structure. 
If, then, in our walks we come up against a mys- 
terious low-growing Pine, with five leaves in a bundle, 
directed upwards (not pendulous), of from 2} to 3 in. 
long, not quite so thickly situated on its yellow-grey 
branchlets as, for instance, the above-mentioned 
Cembra or the Foxtail Pines (P. Aristata and P. 
Balfouriana), then may our suspicions be strongly 
grounded for believing that we have run to his place 
upon earth the Stone Pine from America’s Rocky 
Mountains. 
If we were wishful to make assurance doubly sure, 
we might go so far as to take a leaf home and put it 
under the tell-tale influence of a microscope. If by 
that process we failed to discern a vestige of jagged 
serrulation on its leaves, it would indeed be a case 
of Q.E.D. and our suspicions turned into certainty. 
This bending competition is what we should cordially 
recommend as of most powerful avail in arriving 
at a recognition of this rarely seen tree—to say 
nothing of the diversion it would afford to the ex- 
perimentalists in making a trial of this peculiar 
quality. 
P. ALBICAULIS.—Specimens of this tree are still 
fewer and farther between, if possible, than its 
predecessors of the group. A few of them have been 
tried at Kew and also at Leonardslee, and grow, as 
is the way with this little coterie, slowly but, so far 
they have grown there, surely. 
It is evidently almost a facsimile in appearance to
