Roots with small secondary roots; coral-like roots developing at base of stem at or below soil surface. Leaves pinnately compound , spirally clustered at stem apex, leathery, petiole and rachis unarmed [with stout spines]; leaflets entire or dentate [spinose ], venation dichotomous [netted ]; resin canals absent. Cones axillary , appearing terminal , short-peduncled [sessile], disintegrating at maturity; sporophylls densely crowded, spirally arranged , often covered with indument . Pollen cones soon shed, generally smaller and more numerous than seed cones; sporophylls bearing many crowded, small microsporangia (pollen sacs ) adaxially; pollen spheric, not winged . Seed cones persistent for a year or more, 1(--2) per plant, nearly globose to ovoid , tapering sharply or blunt at apex; sporophylls peltate, thickened and laterally expanded distally, bearing 2(--3) ovules. Seeds angular, inner coat hardened, outer coat fleshy, often brightly colored ; cotyledons 2.
