Description

P. henryi is a monoecious evergreen tree, reaching up to 30m tall and 100cm DBH, typically with a single straight trunk. The bark on mature P. henryi is scaly, fissured, and broken into large irregular plates, which are grey-brown in color, and flaky. The twigs are thick, with new shoots appearing reddish-brown in color. The needles are 7 - 12cm long, and in fascicles of 2, and persist for 2 - 3 years before falling off. Pollen cones appear in clusters at the base of new shoots, and are only 2cm long. Seed cones are thin and woody, and bear a short stout spine.[2]

Some sources also place it in the Vietnamese provinces of Ha Giang and Bac Kan. P. henryi occurs in subtropical mountains, typically at elevations 1,100 - 2,000m, primarily on dry, sunny slopes.[2]
