Pinus nigra is a large coniferous evergreen tree, growing to 20–55 metres (66–180 feet) high at maturity and spreading to 6 to 12 m (20 to 39 ft) wide.The bark is gray to yellow-brown, and is widely split by flaking fissures into scaly plates, becoming increasingly fissured with age.
[15] [16] Overall, there are over 537 plant species found throughout the south Florida rocklands. [17] Pine rocklands are defined by an open canopy of South Florida slash pine with heights ranging from 20–24 meters, but can be less due to past disturbance. [4] Seedlings are fire adapted and spend 2 to 5 years in the "grass stage" building ...
P. e. var. densa (South Florida slash pine, Dade County pine) is found in the pine rocklands of southern Florida and the Florida Keys, including the Everglades. [10] [11] Leaves are nearly all in bundles of two, with longer needles. The cones are smaller, 5–12 cm (2.0–4.7 in), the wood is denser, and the tree has a thicker taproot. [9]
Pinus serotina, the pond pine, black bark pine, bay pine, marsh pine, or pocosin pine, [2] is a pine tree found along the Southeastern portion of the Atlantic coastal plain of the United States, from southern New Jersey south to Florida and west to southern Alabama. [3] Pond pine distribution may be starting to spread west towards Mississippi ...

The species name is contorta because of the twisted, bent pines (shore pine) [8] found at coastal areas and the tree's twisted needles. [9] [10] [11] Pinus contorta is occasionally known under several English names: black pine, scrub pine, and coast pine. [12] [13] P. contorta subsp. latifolia will hybridise with the closely related jack pine ...
The most significant feature of the pine rockland ecosystem is the South Florida slash pine (Pinus elliotti var densa; also called Dade County pine) that reaches a height of 22 feet (6.7 m). Pine rockland communities require fire for maintenance; they have adapted to promote and resist fire at the same time. [50]
