Abstract
The genus spruce (Picea A. Dietr.) belongs to the family Pinaceae, which includes other key taxa of conifers such as pine, fir, and larch. The Pinaceae family is divided into the following three subfamilies: Pinoideae, which includes the genus Pinus only; Laricoideae, with the genera Larix, Cedrus, and Pseudolarix; and Abietoideae, including the genera Abies, Picea, Pseudotsuga, Tsuga, and others. The absence of dwarf shoots is characteristic of the subfamily Abietoideae in which the needles are arranged only on long shoots. In contrast, in the subfamily Pinoideae, needles occur only on dwarf shoots except for the juvenile primary needles of the seedlings. The subfamily Laricoideae exhibits needles on both long and dwarf shoots.
