Encephalartos pterogonus
Mountainous regions.·Arborescent·Not Specified
Encephalartos pterogonus is a species of cycad native to the Manica province of Mozambique, specifically Mount Mruwere and surrounding mountains. It is characterized by its upright stem, pinnate leaves with dark green lanceolate leaflets, and prominent reproductive cones. This dioecious species produces distinct male and female cones, with seeds covered in an orange-red sarcotesta when mature.

About Encephalartos pterogonus
Encephalartos pterogonus is a distinctive species of cycad native to the mountainous regions of Mozambique. Its natural habitat is primarily Mount Mruwere (Monte Urueri) and the surrounding mountain areas within the Manica province. This species is recognized for its robust growth form and striking reproductive structures.
Description and Characteristics
The plant typically features an upright stem that can attain a height of up to 1.5 meters and a diameter of around 40 cm. It is not uncommon for this stem to produce additional growth from suckers at its base, contributing to a multi-stemmed appearance in mature specimens. The leaves of Encephalartos pterogonus are pinnate, measuring an impressive 1.2 to 1.5 meters in length, and they form a dense crown atop the stem. These leaves are supported by petioles that are 4 to 8 cm long. Each leaf is comprised of numerous pairs of lanceolate leaflets, which are dark green in color and generally measure between 15 and 18 cm in length.
Reproduction
Encephalartos pterogonus is a dioecious species, meaning that individual plants are either male or female. The male plants bear one to three spindle-shaped cones that are typically 30–38 cm long and 10–11 cm wide, emerging on stalks. Female plants, in contrast, produce two to three cones that are roughly cylindrical, measuring 35–40 cm in length and 16–18 cm in width, and are noted for their bright green coloration. The seeds produced by this cycad are roughly ovoid, measuring 28–35 mm long, and are characteristically enveloped in an orange-red sarcotesta when they reach maturity.
