Encephalartos tegulaneus

Encephalartos tegulaneus, the Kenyan giant cycad, is a species of cycad endemic to Kenya. It occurs in Eastern Province near Embu, Kenya, and on the Matthews Range in Rift Valley Province.
"E. tegulaneus" ssp. "powsii" is critically endangered due to overcollecting and a very limited distribution. The other subspecies are not critically endangered.
