THE NORWAY SPRUCE.
[Abies[T] excelsa. Nat. Ord.—Coniferæ; Linn.—Monœc. Mon.]
[T] Generic characters. Flowers monœcious. Barren catkins crowded, racemose. Scales of the cone thinned away to the edge, and usually membranous or coriaceous. Leaves never fascicled.
Though a native of the mountains of Europe and Asia in similar parallels of latitude, the Spruce Fir is not considered indigenous to Britain. It must, however, have been introduced at an early period, as it is mentioned by our oldest writers on arboriculture. It is most common in Lapland, Norway, Sweden, Denmark, and throughout the north of Germany. It grows in the south of Norway at an elevation of 3000 feet above the level of the sea, and in the north on mountains in 70° N. lat. at 750 feet. In the valleys of the Swiss Alps, the Spruce is frequently found above one hundred and fifty feet in height, with trunks from four to five feet in diameter. This tree requires a soft moist soil. Among dry rocks and stones, where the Scotch fir would flourish, the Spruce Fir will scarcely grow.
The Norway Spruce Fir is the loftiest of European trees, attaining, in favourable situations, the enormous height of one hundred and eighty feet; with a very straight upright trunk, from two to six feet in diameter, and widely extending branches, which spread out regularly on every side, so as to form a cone-like or pyramidal shape, terminating in a straight arrow-like leading shoot. In young trees, the branches are disposed in regular whorls from the base to the summit; but in old trees the lower branches drop off. The trunk is covered with a thin bark, of a reddish colour and scaly surface, with occasional warts or small excrescences distributed over its surface. The leaves are solitary, of a dark grassy green, generally under one inch in length, straight, stiff, and sharp-pointed, disposed around the shoots, and more crowded together laterally than on the upper and under sides of the branchlets. The barren flowers, about one inch long, are cylindrical, on long catkins, curved, of a yellowish colour, with red tips, and discharging, when expanded, a profusion of yellow pollen. The fertile flowers are produced at the ends of the branches, first appearing as small pointed purplish-red catkins; they afterwards gradually assume the cone-like form, and become pendant, changing first into a green and latterly into a reddish brown, acquiring a length of from five to seven inches, and a breadth of above two inches. The scales are rhomboidal, slightly incurved, and rugged or toothed at the tip, with two seeds in each scale. The seeds, which are very small, and furnished with large membranous wings, are not shed till the spring of the second year.
