Encephalartos tegulaneus over the hillside of Ol Olokwe table mountain, central Kenya
Cycads - the order Cycadales - dominated the Earth among plants in the second half of the Mesozoic era among 250 million and 60 million years ago. In contrast to dinosaurs, who disappeared abruptly towards the end of mesozoic era, the more tenacious cycads, though in a much reduced number of species, have survived to the present day. All cycads are gymnosperm dioecious plants. Cycads are divided into 4 families and at present they can be found in the wild mostly in tropical regions in Africa, the Comores, Madagascar and Mauritius, India, South East Asi and Australia, South, Central and North America and West Indies.
The plants are protected by difficult access to population.
It was recognised as a new species based on collection, photos and paintings by Joy Adamson, of "Born free" fame.

Stangeria eriopus, Umtamvuna Nature Reserve, Kwazulu - Natal, South Africa.
Stangeria eriopus, Natal grass cycad, the only member of the Stangeriaceae family. The plant was originally described as a fern. However in 1951, a plant sent to Kew Gardens by dr. Stanger produced cones and revealed its true cycad character. It differs from other cycads by its peculiar appearance and biochemical composition, for example the absence of bioflavonoids in leaves.
Encephalartos ghellinckii, Drakensberg, Natal, South Africa. One of few cycad species surviving regular snow cover and frosts.

"Without doubt, Cycas micholitzii is one of the most distinctive and beautiful species of the genus. The nearly subterranean stem usually produces only one to three leaves, but beauty of these leaves is hard to imagine...." Loran M. Whitelock, The Cycads, p. 126.
