The Genus Cycas in Australia
by Len Butt

Until the mid-1970's, the genus Cycas in Australia was listed mostly under the species C. media and one or two others. This breakthrough book, published in 1990, brought forth the thesis that there are many more Cycas species than were previously thought, including various species of numerous color forms.
This is a non-technical book on the Australian representatives of this genus, which includes 14 species and has a widespread distribution and a wide diversity of form. It contains color and b/w photos throughout.
