Encephalartos poggei is a species of cycad in the family Zamiaceae.[4] It is referred to by the common name Kananga cycad. It is native to Angola, the Democratic Republic of the Congo and Zaire.[3][1]

Description

This cycad has an upright stem, reaching up to 2 meters tall and 20–30 centimeters in diameter. Its pinnate leaves, measuring 70–150 centimeters long, form a crown at the top of the stem. Each leaf is supported by a 7-20 centimeter long petiole, lacks thorns, and is covered in a greyish tomentum. The leaves are composed of 18-60 pairs of lanceolate, leathery leaflets, averaging 8-15 centimeters long, and have a glaucous green color.

This species is dioecious, with male specimens bearing 1-3 cones that are sub-cylindrical, 16–20 centimeters long, and 3–7 centimeters wide. These cones are greenish to orange-yellow. Female specimens have 1-3 ovoid cones, 17–23 centimeters long and 9-12 centimeters in diameter, initially green and turning yellow when ripe.

The seeds are roughly ovoid, measuring 20–33 millimeters long, and are covered with a red-brownish sarcotesta.[5]
