A tree of from 25 to 50 leet in height, hem ftraight. Branches few, thinly and irregularly fcattered. 
Buds * furrounded by imbricated fcales, moderate in fize and conical [fig. 1 ]. Leaves in threes, of a light 
green colour, four or five inches long, twifted, fo as to make a turn of an inch and a 
half from bafe to tip ; ftiff, ftrong, triquetral, rounded on the back, keeled on the inner 
fide'; all three margins ftrongly ferrate, bearing eight nearly equally diftant rows of 
ftomata on the rounded back, with a flightly wider interval in the middle; and about 
four on each fide of the inner Tides (fometimes three, fometimes four, and fometimes 
three on the one fide and four on the other), [figs. 2 and 3]. Sheaths fhort and fmall 
[%■ 4]; dark umber brown where expofed ; reddifh brown where not expofed ; pale at 
the tranflucent margins; fhorter on the older leaves. Inflorefcence not obferved. Cones aggre¬ 
gated together in clufters, feffile, growing chiefly on the main ftem, from which they ftand out 
nearly at right angles when young, pendent and firmly aclpreffed to it 
when old; nearly ftraight on the inner fide, curved on the outer, of an 
unequal conical fhape, varying in length from four to fix or even eight 
inches; hard, gloffy, not refinous, fawn-coloured, but lofing this colour 
and becoming darker when old. The cones on the young trees have 
the fcales on the outer fide, particularly towards the bafe, very prominent, projecting horizontally, 
conical, and deeply divided from each other, giving occafion to the fpecific name tubercitlata [fig. 
5]. The cones on the old trees [fig. 6] lofe in a great meafure the ftrongly tuberculate form. 
Scales [fig. 7] wedge-fhaped on the outer fide, dilated, and quadrangular at the apex, with a fhort 
hooked tooth on the umbo, turned towards the tip of the cone; on the inner fide fmaller and flat; 
the hooked tooth on their umbo being either abfent or a mere prickle. The fcales are arranged on a fpiral
