The loblolly pine ( Pinus taeda ), also American turpentine pine called (Note the use), is a plant from the genus of pine ( Pinus ) within the subfamily of Pinoideae from the family of Pinaceae (Pinaceae). It is the official state tree for the US state of Arkansas .
description
The frankincense pine is an evergreen tree that grows to heights of 30 to 35 meters with a trunk diameter of 50 to 100 centimeters, and rarely more. Individual specimens in particularly suitable locations can even reach a stature height of 45 meters; these specimens are the largest pines from the group of the US southern states pines. The bark is reddish brown in mature trees and breaks into scaly plates. The approximately 12 to 22 cm long needles are grouped into three short shoots. This is an average length for the US Southern Pine group, shorter than that of the swamp pine ( Pinus palustris ) or Pinus elliottii on the one hand, but longer than that of Pinus echinata and Pinus glabra on the other.
They are single sexed ( monoecious ). The cylindrical, male cones are 20 to 40 mm long and yellow to yellow-brown. The initially greenish cones are light to dark brown when ripe. Their length is about 7 to 13 cm. Their diameter is 2 to 3 cm when closed, increases to 4 to 6 cm after opening. Each cone scale has a sharp spike that is about 3 to 6 mm in size. The 5 to 6 mm large, red-brown seed has wings up to 20 mm long.
The number of chromosomes is 2n = 24.
distribution
The frankincense pine is native to the southeastern United States . Their occurrences extend along the Atlantic coast north to Delaware , south to northern Florida . Northwest inland, the occurrence extends to Tennessee ; in a westerly direction the distribution area extends roughly to the Mississippi River; there are also isolated occurrences in central Texas ; the famous "Lost Pines" in the area around Bastrop (Texas) and deposits along the Colorado River (Texas) in Texas are among them.
Systematics
Pinus taeda was first described by Carl von Linné in his work "Species plantarum", page 1000 in 1753 . Synonyms are Pinus lutea Walter and Pinus mughoides E.HLKrause .
"Eisenhower Tree"
Probably the most famous specimen of an incense pine stood on the Augusta National Golf Course in Georgia; Since the former US President Dwight D. Eisenhower often hit his golf balls in this tree, this specimen was also called the Eisenhower Tree . In February 2014 it had to be felled due to the severe damage caused by an ongoing cold spell.
