P. varidbilis Lamb. Pin., ed. 2., 1. t. 14.3 and our jig. 1828. of the natural 
size, from Lambert’s plate.—Mr. Lambert describes this pine as having the 
leaves in twos and threes, 2 in. long, channeled, the margins and nerves rough, 
and the apexes sub-keelshaped; the sheaths short, straight, and but little 
wrinkled. The cones solitary, recurved, pendulous, narrow-ovate, muricate ; 
spines subincurved, with the scales dilated in the middle. He has only seen 
two trees of this species in England; one at Pain’s Hill, and the other at 
Kew. (Lamb.) The one at Kew no longer exists; and the only trees at 
Pain’s Hill, that we could see, with cones resem- 
bling those in Mr. Lambert’s plate, had three leaves, 
and appeared to us to belong to P. Te‘da.' The 
bads in Mr. Lambert’s figure appear to be resinous, 
and are nearly smooth (see fig. 1829.), but those of 
P. variabilis at Dropmore, which we feel confident is 
the P. mitis of Michaux (which Mr. Lambert makes 8 
a synonyme of his plant), are scaly, with the scales 
reflexed, as in fig. 1810. in p. 974. The young 
shoots in Mr. Lambert’s plate are green, but in the 
Dropmore plant they are of the same violet glau- 
cous hue as those of P. inops; a character so 
remarkable that it cannot be mistaken, and which, 
Michaux says, belongs to no other pine of the United 
States but P. inops and P. mitis. (NM. Amer, Syl., 
iii, p. 130.) It is found also in P. Sabinidna and P. 
Coulteri ; but with these species Michaux was not 
acquainted, and besides they are not natives of the United States. P. vari- 
1829. P. varidbilis.
