Encephalartos humilis

Encephalartos humilis is a small cycad species native to the former Transvaal Province of South Africa. It is characterized by its subterranean stem and leathery, pinnate leaves that form a crown. This dioecious species produces distinct male and female cones, with seeds enclosed in colorful flesh.

Key Facts

  • Features a small, underground stem typically not exceeding 50 cm in height.
  • Possesses pinnate leaves, 30–50 cm long, with leathery lanceolate leaflets.
  • It is a dioecious species, meaning male and female reproductive structures are on separate plants.
  • Male cones are spindle-shaped (15–20 cm long), while female cones are cylindrical (approx. 25 cm long).

About Encephalartos humilis

Encephalartos humilis is a species of cycad indigenous to the former Transvaal Province of South Africa. This particular cycad is recognized for its diminutive stature, featuring an underground stem that typically does not exceed 50 cm in height and measures 15-20 cm in diameter. It occasionally produces secondary stems from basal shoots, contributing to its overall form.

Botanical Description

The species presents pinnate leaves, numbering between five and eight, which emerge in a crown atop the stem. These leaves can reach lengths of 30–50 cm, with a petiole of approximately 10 cm. They are composed of numerous lanceolate, leathery leaflets, each up to 13 cm long, characterized by smooth edges and roughly nine parallel veins on their lower surface. The rachis, or central stalk of the leaf, is greenish-yellow.

Encephalartos humilis is a dioecious plant, meaning male and female reproductive structures are found on separate individuals. Male plants bear spindle-shaped cones that are 15–20 cm long and 4–5 cm wide, exhibiting a brownish-gray coloration. Female plants produce solitary, roughly cylindrical cones, measuring about 25 cm in length and 8–10 cm in width, also in a brownish-gray hue. The seeds are ovoid, approximately 2.5-3.5 cm long, and are enveloped in flesh that varies from light yellow to orange.
