A tree, attaining in Mexico 70 ft. in height. Bark brownish red, irregularly 

 divided into scaly plates. Young branchlets stout, glabrous, reddish brown ; their 

 decurrent pulvini prominent, keeled, and persistent, with the epidermis peeling off in 

 the second or third year, leaving a greyish-coloured surface. Buds ovoid, pointed, 

 about an inch long, reddish brown, scarcely resinous ; scales ending in long acuminate 

 points, with their bases interlaced by whitish marginal fimbriae. The brown linear- 

 lanceolate scale-leaves with white fimbriae, persist during the first year. 



Leaves in fives, persistent three years, 4 to 18 in. long, crowded on the branch- 

 lets, spreading, serrulate, with stomatic lines on the three surfaces, ending in a 

 cartilaginous point ; resin-canals median ; basal sheath i| to 2 in. long, persistent. 

 Flower buds, with the staminate catkins concealed, and not apparent as swellings 

 externally. 



Cones, in the first year, subterminal, single or in clusters of 2 to 5, stalked, pale 

 or deep brown, blue, or dull black ; scales armed with usually reflexed prickles. 

 Mature cones 2\ to 10 in. long, subsessile or stalked, spreading or deflexed, nearly 

 cylindrical or ovoid-conic and tapering, often curved, opening when ripe, and falling 

 soon afterwards, when their stalks and a few basal scales often remain on the branch ; 

 scales variable in size ; apophyses flat, pyramidal, tumid, or slightly protuberant and 

 reflexed, dull yellowish, reddish brown, dark brown, or nearly black, prickles 

 usually obsolete. Seed oval, brownish mottled with black, \ in. long ; wing 

 narrow, an inch or more in length. 



This species is very variable, both in the length of the leaves and in the size of 

 the cones ; and is met with, according to Shaw, at all altitudes 3 in Mexico, except 

 in the lowlands of the coast, and below 3000 ft. in the interior, where the climate is 



1 Roezl's Catalogue of 82 new Mexican species, published in 1857, does not contain, according to Shaw, a single new 

 species. They represent six or seven pines, all of which had been previously described. Roezl's list is given by Masters, in 

 Journ. Linn. Soc. (Bot.) xxxv. 648, and will not be further noticed by us. 



2 The type specimens of the cones of these two species are preserved in the Botanical Museum, Cambridge. P. filifolia 

 is labelled Guatemala. 



3 Gadow, in Journ. Linn. Soc. (Bot.) xxxviii. 432 (1909), makes the timber line in southern Mexico 13,500 to 

 14,000 ft., where there are only a few scattered trees of P. Afontezuma.
