![* Cones cylindroid, pendent, slightly curved, 15—25 cm. long, much longer than broad; seed-wing 3—4 times as long as marbled seed. t Cone 15—18cm. long; seed 5—7mm. long; seed-wing 25 mm. long, oblong-oblique, with nearly parallel edges. Pinus Strobus, L. Weymouth Pine (Fig. 74). [Pinus monticola has a somewhat larger cone, stiffer and less serrulate leaves, and smaller seeds and wings than P. Strobus.] tt Cone 18—24 cm. long; seed 7—8 mm. long; seed-wing 30—40 mm. long, wider just below middle. Pinus excelsa, Wall. Himalayan Pine. ** Cone ovoid-obtuse, erect, 8 —10 cm. long, and seeds 8—12 mm. long with a very short broad wing projecting only 2—4 mm. Pinus Gernbra, L. Arolla Pine (Fig. 75). ({3) Apophysis and umbo wanting; scales thin and rounded; leaves not in twos, threes or fives. * Cones cylindroid, erect; the rounded scales falling when mature; seed triangular, with oleo-resinous coats, wing inseparable. Abies pectinata, DC. Silver Fir (Fig. 76). Cone 18—32 cm. long x 5—6 cm. wide. The barren scale pro- jects beyond the ovuliferous scale and ends in a sharply reflexed mucro. Seeds 10—12 mm. long, triangular, with a weak, easily crushed shell abounding in balsam. Wing somewhat obliquely rectangular 20—22 x 5—7 mm., and is with difficulty removable. Leaves linear, isolated, pectinate in arrangement.](https://iiif.wellcomecollection.org/image/b20996068_0084.jp2/full/800%2C/0/default.jpg)
