Cycads of South Africa by Cynthia Giddy
Cycads are the most primitive living seedbearing plants known and belong to an ancient order, the Cycadales, which flourished in the Carboniferous period 50 to 60 million years ago. The cycads we know today have changed little in their basic character.
This book contains a description of the stem, leaves, seeds and cones of each of the twenty-nine South African species with a colour plate showing details of male cones, female cones, leaf details and plants in their natural habitats. These are supplemented by pencil and pen and ink drawings by Barbara Jeppe.
There are sections on the propagation of cycads, hybrids, damaged plants and their regrowth, pests and diseases and on special laws for the protection of cycads.
