About Pinus glabra Walter
Pinus glabra Walter, also called spruce pine, is a straight-growing, medium-sized pine species. Mature individuals reach heights between 20 and 40 metres (66 to 131 ft). Its leaves are needle-like, growing in bundles of two. Each needle measures 5 to 8 centimetres (2.0 to 3.1 in) long, is 1 millimetre (0.039 in) thick, and has a glossy dark green appearance. This species produces small, slender cones that are 4 to 6 centimetres (1.6 to 2.4 in) long. The cone scales have weak prickles that are shed soon after the cones mature. In terms of ecology, Pinus glabra differs noticeably from most other pines. It does not grow in largely pure pine forests; instead, it is typically found as scattered individual trees in moist woodland habitats within mixed hardwood forests. To compete successfully in these shaded habitats, it has evolved higher shade tolerance than most other pine species.
