the back, and with three, four, or five rows on each of the inner sides [figs. 3 and 4]. Sheaths half an inch 
long, falling off very soon, so that they are only seen on half-developed 
leaves, and surrounded by long straight membraneous imbricated brown 
scales [fig. 5 natural size, and fig. 6 the same magnified]. It flowers 
from the end of April to the middle of June, according to exposure, and 
the cones take eighteen months to mature. Male catkins purple, ter¬ 
minal, and sessile, surrounded by brown imbricated scales, short, obtuse, 
conic [fig. 7, a cluster of catkins; and fig. 8, a single catkin, magnified] ; 
the anthers bilocular, the crest oval, and with a lacerated margin [fig. 9 Fi s- 3- Fig. 4 - 
front view and fig. 10 side view]. Female catkins, growing three or four together, oblong 
cylindrical, with a very short peduncle, which afterwards becomes longer. 
[Fig. 11 shews the young female catkin of its natural size, and fig. 12 the 
same magnified.] Cones, before impregnation, erect, and violet rose colour; 
after impregnation, pendent, and with a dull greenish hue spreading over them 
like a bloom, afterwards pale brown ; about 6 inches long, cylindrical, smooth, 
and slightly curved and pointed at the apex, ripening in September and 
October of the second year. Scales loosely imbricated, elongate, somewhat wedge-shaped, 
with the apophysis slightly thickened in the 
middle, thinned at the edges, obliquely rounded \ 
at the margin, very finely longitudinally striated, 
and with a slightly pointed, short, broad, darker 
Flg ' 2 umbo at the apex, constricted at the base [fig. 
13 back, and fig. 14 front of scale from middle of cone, grown 
in the Himmalayas; and fig. 15 back and fig. 
16 front of similar scale from English-grown 
specimen]. The remains of a bract, usually 
irregularly broken and defaced, adhere to the 
back [fig. 17 natural size, and fig. 18 magni- 
The seeds [fig. 19 foreign growth, and fig. 20 English 
growth] are not very large (about the size of a 
small pea), ovate, flattened on both sides, black, 
with some grey spots ; wing from three-fourths 
to an inch in length, oblong obtuse, with the 
back straight. The cotyledons average about 
The cones shed their seeds towards the latter end of November, but remain for many 
months afterwards hanging to the branches. 
This species is very closely allied in habit and 
the figure of its cones to Pinus Strobus and P. 
monticola. Lambert first pointed out the difference 
in the crest of the anthers, which is a good specific 
character. The form of the crest of the anther in 
P. Strobus is represented in figs. 21 and 22, copied 
from Lambert, which may be contrasted with fig. 
10 above and fig. 23, a less characleristic drawing 
copied from Lambert. The greater size of the leaves and the larger cones, and the general habit of 
the tree, furnish characters which, although not perhaps so easily described, are more easily recognisable. 
Major Madden notes that on the northern side of the Roopin Pass many specimens may be noticed 
with bright green leaves, which at other places are mingled with foliage of the glaucous green proper 
to the tree on the lower mountains. Dr
