The document provides descriptions of several conifer species: - Spruce have single sharp needles that snap when bent and leave a stalk on the stem. Spruce cones are irregularly notched. - Firs have flat flexible needles that don't snap. Needles point up and cones also point up. Firs are softer than spruce. - Douglas Fir is not actually a fir but has fir-like characteristics. Cones hang down and remain intact on the tree.
