Microcycas calocoma

The plant grows up to 10 m tall with an upright, sometimes branching trunk that grows to 30-60 cm in diameter. The leaves are dark green and 0.6-1.2 m long. One unique character is that the leaves appear to be truncated near the apex because the middle and distal leaflets have similar lengths. The petioles are 8-10 cm long and lack spines; the rachises also lack spines. Leaflets are light to dark green, lanceolate, articulate at the base, and leathery with an entire margin. Middle leaflets are 15-25 cm long by 0.8-1 cm wide. Male cones are cylindrical, 25-30 cm long and 5-8 cm in diameter, yellow-brown, and hairy. Seed cones are broadly cylindrical, 50-90 cm long and 13-16 cm in diameter, yellow-brown, and hairy. The sporophylls have two round apical projections. The elliptical seeds are pink or red in color, 3.5-4 cm long and 2-2.5 cm in diameter.
