Description

This palm-like cycad grows up to 3 metres tall with stems that are 15–25 cm in diameter. Its leaves are 80–110 cm long, either blue or semi-glossy silver. The leaflets are 14–21 cm long and 8–13 mm wide, lanceolate, and have an entire margin or sometimes with 1–2 very small teeth. They grow in pairs at a 180° angle along the rachis. [4] The plant is dioecious, meaning it has separate male and female specimens. Male specimens have 1-3 green ovoid cones that are 18–25 cm long and 6–8 cm in diameter with green to silvery colour.[ citation needed ] Female specimens have 1-2 oval cones of the same colour, which are larger at 30–35 cm long and 12 cm in diameter. Both male and female cones are described as being silvery in colour.[ citation needed ] Both types of cones appear in January, the middle of summer in the southern hemisphere. The seeds are 20–25 mm long, 15–20 mm wide, and covered with an orange sarcotesta (similar to an aril). Both the macrosporophylls and microsporophylls have a flat, smooth, and glabrous surface.

Etymology

Encephalartos is from the Greek for a 'bear's head'. The species name inopinus is Latin and means 'unexpected'.
