Taxonomic Notes

Syn: Pinus oocarpa var. microphylla Shaw 1909 (Farjon & Styles 1997).

J. A. Pérez de la Rosa has recently (2009) described a new species, Pinus georginae, that closely resembles P. praetermissa. It is endemic to the southern Rio Ameca basin in Jalisco, Mexico. Thus far I have no further information.


Trees 12-15(-20) m tall and 30 cm dbh. Branchlets flexible, slender, reddish brown, 2-4.5 mm thick. Leaves in fascicles of 5, 8-16 cm long, 0.5-0.7 mm wide, light green, ascending on the branchlets, minutely serrulate; stomata on all faces; fascicle sheaths persistent, 11-14 mm long, light reddish brown greying with age. Immature cones "almost exactly simulating those of Pinus oocarpa;" broadly ovoid and short-acute, symmetrical, light brown, smooth or sometimes with protuberant apophyses, 5.5-7 cm long on peduncles 3-3.5 cm long and 3-4 mm thick; cones opening widely, so about as long as wide. Cone scales not crowded toward the base (as in P. oocarpa) but more uniformly spreading-ascending or recurved: up to ca 25 of the small basal scales persistent on the peduncle when the cone falls. leaving a scar up to 3 cm across at the base of the cone: seed-wing thickened (1-1.5 mm thick) above the base.
