Pinus massoniana var. hainenensis is an extremely rare variety of Pinus massoniana in the family Pinaceae that is endemic to a very small western portion of the island of Hainan, China, presumably on hillsides. [2] The variety was described by Wan Chun Cheng and Li-kuo Fu in 1975. [3]

Mature height and width is unknown, although the trunk is a red-brown color. Branches spread out horizontally. Needles reach a length of 12-20 cm (4.72-7.87 in.), and are slender. Cones are ovoid-cylindric, being 4-7 x 2.5-5 cm (1.57-2.75 in. x 0.88-1.96 in.) long. [4]

It grows within a temperate climate; potentially growing beside Pinus fenzeliana . [5]

Pinus massoniana var. hainenensis was listed and assesed as "Critically Endangered" by the IUCN Red List, for logging and localized deforestation are affecting its limited populations. [6]

It is used as wood or timber by locals for personal uses such as furniture making. [2]

Pinus peuce is a species of pine native to the mountains of North Macedonia, Bulgaria, Albania, Montenegro, Kosovo, the extreme southwest of Serbia, and the extreme north of Greece, growing typically at (600-) 1,000-2,200 (-2,300) m altitude. It often reaches the alpine tree line in this area. The mature size is up to 35–40 m height, and 1.5 m trunk diameter. However, the height of the tree diminishes strongly near the upper tree line and may even obtain shrub sizes.
