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 assessed 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]
