Pinus serotina (Pond Pine, Marsh Pine, 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 attains the height of 15-20 m, occasionally up to 30 m.
The needles are in bundles of three or four, and of length 15-20 cm. The almost round cones are 5-9 cm long with small prickles on the scales. Its cones are serotinous and require fire to open. The Pond Pine is found in wet habitats near ponds, bays, swamps, and pocosins.[1]
The species name 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.
