Compiled by H.F. Glen

Description:

  • Trees or shrubs, dioecious, evergreen
  • Leaves spirally arranged, subopposite or whorled, rarely opposite, linear to narrowly ovate or scale-like, long-persistent
  • Male cones usually consisting of many fertile scales, each bearing 2 pollen sacs, axillary, rarely terminal, sessile to shortly stalked, catkin-like, solitary or in groups of 2-5; pollen grains usually with 2 air-bladders or wings
  • Female cones axillary, on thin naked stalks or on short leafy or scaly branches, usually reduced to 1 or 2 fertile, terminal scales and a few sterile, lower scales fused with each other and with cone axis; fused cone axis and scales beneath seeds either remain woody or become swollen and often fleshy at maturity (receptacle)
  • Ovule solitary, adnate to face of fertile scale, inverted and enclosed in a false aril (epimatium) arising from face of scale and adnate to single integument
  • Seeds ellipsoid to globose; testa and false aril form a coriaceous or externally fleshy and internally ± woody shell; embryo axile; cotyledons 2
  • x = 13
