Encephalartos nubimontanus is extinct in the wild and used to occur in the Drakensberg in the Limpopo province, South Africa. Plants were found along the mountain range to the north and east of Penge. Encephalartos nubimontanus is one of the rarest blue cycads , a spectacular arborescent palm-like species, that slowly grows up to 2.5 m tall, with a crown of arching silvery-blue, leaves up to 1.4 metres long, and distinctive blue green cones. As with all cycads this species is dioecious. Male plants may carry up to 15 cones, whereas only one or two occur on the females. Derivation of specific name: The specific name 'nubimontanus' (Latin nubis, blue-black, and montanus, mountain) translate into ‘growing on the blue-black mountain'.
