collection must be amongst the largest; it is an old, rugged 
specimen with the characteristic long leaves in conspicuous tufts 
at the ends of the branches, its trunk 4 ft. 4 in. in circumference. 
Of the sugar pine (P. Lambertiana), whose wonderful cones are 
sometimes 21 in. long, there is a fine tree 80 to 90 ft. high, its 
trunk girthing 9 ft. 4 in.; this tree occasionally bears cones. 
The Jack pine (?. Banksiana), although introduced nearly 120 
years ago is not common in England in any great size; here is 
one over 30 ft. high, bearing many of its curious small cones 
tapered and curved at the end and retaining them on branches 
several years old. Of a series of forms of the white pine (P. 
Strobus), one of the most noteworthy is a tree of the var. nivea 
of slender, pyramidal form, its grey smooth trunk girthing 5 ft. 
e western representative of the white pine in North America 
is P. monticola, of which. there is here a fine tree 80 to 90 ft. 
high with a trunk 6 to 7 ft. round. A specimen of P. ponderosa, 
although scarcely so impressive as the famous tree at Bayford- 
bury, in Hertfordshire, must be one of the finest in this country ; 
I estimated its height to be about 90 ft., and its trunk- measures 
9 it. 5 in. in cireumference. One of the least imposing of pines 
is the Jersey, or scrub, pine (P. virginiana or P. inops), from the 
Eastern United States, and it is rarely planted now; at Bicton a 
tree of spreading habit and horizontal branching is 4 ft. 8 in. 
in girth of trunk, 
_ Of the Mexican pines the most notable in this collection, 
perhaps, is P. patula. It is only in the south-western counties of 
England and in places with a similar climate that this species 
can be seen in really good condition, but there its long, slender, 
pendulous grey needles make it one of the most distinct of all 
pies; at Bicton there is a very good example over 50 ft. high 
dividing near the ground into two great limbs, beneath which 
the trunk measures 11 ft. 9 in. in girth. From Mexico also comes 
ia Ayacahuite, represented at Bicton by probably the finest tree 
rich green foliage, its trunk girthing 10 ft. 2 in. A tree grown 
as P. Don Pedri is also P. Ayacahuite. A third Mexican pine is 
E. Teocote, bearing its long, stiff, spreading leaves in threes, a 
tree at Bicton is over 60 ft. high, its trunk 7 ft. in girth; this 
tree Js extremely rare in cultivation. A commoner one, also 
fexican, is P. Hartwegii, sometimes regarded as a short-leaved 
variety of P. Montezumae. Of two trees at Bicton one approaches 
80 ft. in height and is about 6 ft. round the trunk. This is pro- 
= a good tree in Windsor Forest. Under the name. of P.
