Plantae

Leaves stiff or scarious, needle or scale-like, in ×-section flat, nearly terete, or variously angled, with or without an obvious midvein and generally lacking noticeable secondary venation; leaf arrangement alternate, opposite, whorled, or grouped into fascicles of 2-5 with a scarious sheath at the base; seeds not enclosed by an ovary or a true fruit, either borne naked on the upper surface of ovuliferous scales aggregated into a cone (the cone sometimes modified and fleshy and “berrylike) or the seed solitary and mostly or completely enclosed in a fleshy or leathery aril or receptacle; [Gymnosperms]
