Encephalartos relictus P.J.H.Hurter | |
Encephalartos relictus, also known as the Parlota cycad, is a species of cycad in Eswatini. The cycad is evolutionarily extinct; the cycad has only male plants, meaning that they cannot produce seeds. However, J. J. P. du Preez was able to propagate some offshoots of the specimens. [3]
It is a cycad with an arborescent habit, with a stem up to 2.5 m tall and 40–45 cm in diameter, with secondary stems originating from basal suckers. The leaves, pinnate, of a bluish-green color, are 1–2 m long, supported by a petiole about 15 cm long, and composed of numerous pairs of lanceolate, coriaceous leaflets, arranged on the rachis with an angle of about 40°, long up to 20–25 cm, with entire margin and a pungent. It is a dioecious species, of which, however, only male specimens are known which have from 1 to 3 sub-conical cones, about 20–24 cm long and 12–15 cm broad, of greenish-yellow sarcotesta. [4]
Encephalartos horridus, the Eastern Cape blue cycad, is a small, low-growing cycad up to 0.9 m (3.0 ft) high and 0.9 m (3.0 ft) wide. It is a native of Eastern Cape Province, South Africa, and found in arid shrublands, most commonly on ridges and slopes with shallow soils. The species is particularly known for its distinctly blue-gray leaves, although the degree of coloration can vary significantly. The species name horridus is Latin for 'bristly', after the plant's stiff, spiny leaflets.
Encephalartos lebomboensis is a species of cycad in the family Zamiaceae. Native to the Lebombo Mountains of South Africa, the species was first described in 1949 by the South African botanist Inez Verdoorn. It is commonly known as the Lebombo cycad, although the name is also used for Encephalartos senticosus which also occurs in the same locality.
Encephalartos senticosus is a species of cycad in the family Zamiaceae native to the Lebombo Mountains of Mozambique, Eswatini (Swaziland), and the KwaZulu-Natal province of South Africa. Prior to its description in 1996, Encephalartos senticosus had been confused with the closely related and sympatric Encephalartos lebomboensis. Both species are commonly known as the Lebombo cycad.
