1828. P. variabilis. 



P. variabilis Lamb. Pin., ed. 2., 1. t. 14.; and our fig. 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 iMr. Lambert's plate, had three leaves, 

 and appeared to us to belong to P. Tas'da. The 

 buds 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. raids of Michaux (which Mr. Lambert makes 

 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. (N. Amer. Syl., 

 iii. p. 130.) It is found also in P. Sabmiuna 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. varifcbilis.
