Reminding me of either jellyfish or wearers of grass skirts, the drooping clusters of needles borne by long branches of smooth-bark Mexican pine or Oaxacan pine do seem to float or dance in a light breeze.
Sometimes labeled in cultivation as Pinus oaxacana (like this specimen was), the Gymnosperm Database site goes into some of the details as to why Pinus pseudostrobus var. apulcensis is presently the preferred nomenclature. The epithet pseudostrobus is a reference to a superficial resemblance to Pinus strobus, while apulcensis refers to the Apulco area of Mexico’s Hidalgo State, where this taxon was first collected for Western science in 1839.
A tree reaching a height of up to 45m (~150 ft.), Pinus pseudostrobus var. apulcensis is native to southern Mexico, Guatemala, and El Salvador. It inhabits montane to high montane environments, within a range of 800-3250m (~2600-10500 ft.) above sea level. In its native range, it is a timber species, with the relatively knot-free wood important for light construction, carpentry, wall paneling, veneers, boxes, and matches (ref: A Handbook of the World’s Conifers by Aljos Farjon). The species has also been planted as a timber tree in Africa and India.
