Published in 1970, this book proposes an impressive series of 312 color pictures of lithops. The variability of every species is well illustrated by several distinctive pictures. It is a pity that some pictures exhibit a dominant green-blue shade.

We still need an authorization of D. Sprechman, C. Dugdale and H. de Boer heirs. If you can help us to find some of them, please contact us
