are attached singly to the branches with a base resembling a suction cup, and by their cones, which, like those of true cedars, stand upright on the branches like candles and disintegrate at maturity. Identification of the different species is based on the size and arrangement of the leaves, the size and shape of the cones, and whether the bract scales of the cones are long and exserted, or short and hidden inside the cone.

Phytochemistry

''Abies'' produce a variety of terpenoids. The analyses of the Zavarin groupfrom Smedman et al 1969 to Zavarin et al 1977showed variation in terpenoid composition of the bark by genetics, geography, age and size of the tree.
