Information

Trunk 30–200 cm. high and 30 cm. diameter. Leaves narrow oblong, tapering gradually to the base, rhachis distinctly grooved between the leaflets. Median leaflets oblong to lanceolate, ± coriaceous, upper margin ± straight, lower upcurved to the forwardly directed spiny tip, margins with 2–7 spiny teeth often crowded to the base, basal attachment 5–9 mm. wide, lower surface striate with 26–43 parallel nerves; lower leaflets ovate-lanceolate, spiny, passing to 3–2-furcate and simple spines, ceasing just above the swollen base. Male cones narrow ellipsoid or tapering in the upper half, 12–20 cm. long, 3.0–4.5 cm. diameter, peduncle 10–15 cm. long, 5–12 mm. diameter; median scales horizontal, triangular, 12–22 mm. long, bulla deflexed, 15–25 mm. wide, 6–10 mm. deep, rhomboid to plano-convex, puberulent, terminal facet lenticular to compressed-rhomboid, 1/3–2/3 as wide as the bulla. Female cones cylindrical, about 23 cm. long, 11 cm. diameter, bulla of median scales deflexed, 4.5–5.0 cm. wide, 2.0–2.7 cm. deep, rhomboid, with the adaxial margin rounded, obscurely ridged, the sagittal crest of coarse, rounded warts, abaxial face receding, seminal ridges distinct, tuberculate dentate, terminal facet rhomboid to semi-elliptic, 14–17 mm. wide, lateral lobes triangular to irregular, 3–6 mm. long with lateral facets warty ridged and the angles tuberculate dentate.
