Pinus taeda
species of plant
Pinus taeda, commonly known as loblolly pine, is a species of conifer in the family Pinaceae, a pine native to the Southeastern United States, from East Texas to Florida, up to southern New Jersey. The wood industry classifies the species as a southern yellow pine. U.S. Forest Service surveys found that loblolly pine is the second-most common species of tree in the United States, after red maple. For its timber, the pine species is regarded as the most commercially important tree in the Southeastern U.S. The common name loblolly is given because the pine species is found mostly in lowlands and swampy areas.
Loblolly pine is the first among over 100 species of Pinus to have its complete genome sequenced. In March 2014, it was the organism with the largest sequenced genome size. Its genome, with 22 billion base pairs, is seven times larger than that of humans. As of 2018, assembly of the axolotl genome (32Gb) displaced loblolly pine as the largest assembled genome. The loblolly pine was selected as the official state tree of Arkansas in 1939.
Description
Loblolly pine can reach a height of 30–35 meters (98–115 feet) with a diameter of 0.4–1.5 m (1.3–4.9 ft).
“Pinus taeda” enters the record as species of plant. Crown Archives preserves that source wording while asking what Pinus, taeda and species can confirm, complicate or overturn.
Why this record matters
“Pinus taeda” is worth following because a concise public description often conceals a longer documentary argument. Here, Pinus, taeda and species provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Sep 18, 2026. The linked authority identifier is Q368248. The Library of Congress control number is sh85077898. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2014, 2018 and 1939.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
