Natural range |
Pinus serotina, the pond pine, marsh pine or pocosin pine, is a tree found along the Atlantic coastal plain of the eastern United States, from southern New Jersey south to Florida and west to southern Alabama. This pine often has a crooked growth pattern and an irregular top and grows up to 21 metres (69 ft) high,[1] rarely to 29 metres (95 ft).[2]
The needles are in bundles of three or four, and 15–20 cm (6–8 in) long. The almost round cones are 5–8 cm (2–3 1⁄4 in) long with small prickles on the scales. Its cones are usually serotinous, requiring fire to open.[1] The pond pine is found in wet habitats near ponds, bays, swamps, and pocosins.[3]
The species name serotina is derived from the persistently unopened cones that may remain closed for several years before they release their seeds; the opening is often in response to forest fires.
At the north end of its range, it intergrades and hybridises with pitch pine (P. rigida); it is distinguished from that species by the longer needles and on average slightly larger cones. Some botanists treat pond pine as a subspecies of pitch pine.
- Pond pine cones are smaller and rounder than loblolly pine cones.
- Unlike loblolly pines, pond pines have the ability to grow needles directly from the trunk.[4]
