of Lambert, discovered by Humboldt and Bonpland, on 
Orizaba and other mountains of Mexico. As this variety 
appears distinct I propose to distinguish it as 
Pinus MONTEzuMiE, /3. Cubensis, foliis ternis prcdongis acuminatis 
striatis , margine scabris intus carinatis concoloribus , amentis mas - 
culis fuscatis elongatis , antherarum crista rotundata convexa integrius- 
cula maxima . 
Leaves always in 3’s, 7 to 8 inches long, rigid and serru- 
lated, with a longish rigid acuminate point, the keel shallow 
and also rough ; sheath persistent, rather short, the outer 
stipular scales torn on the margins. Male aments about 
two inches long! the scale-like brown summits of the con- 
nectivum of the anthers imbricated almost like the scales 
of a fertile cone; two-thirds of a line wide, rounded, almost 
reniform, the border equal somewhat paler and membrana- 
ceous, slightly eroded, (as seen through a glass). Anthers 
2-celled.
