B. A. ROBERTS&J. PROCTOR The term 'serpentine' referring to rocks and min of each of the polymorphs. These conditions in erals, can be traced back to the ancient Roman clude temperatures of generally less than 530°C, era of Dioscorides (A. D. 50) (Faust & Fahey and fluid pH's in excess of 10 with low pC02 Serpentine protoliths are essentially ultramafic 1962) and they suggest that the speckled colour of serpents and the fact that Dioscorides recom rocks which fall into a number of categories: (a) mended it for the prevention of snakebite as two stratiform complexes, (b) concentrically zoned complexes, (c) ophiolite complexes and, (d) high of many origins of the name. It is well known that the use of serpentinized rocks by sculptors temperature peridotite complexes. The most and carvers since ancient times is a tradition that commonly recognized are generally assigned to the ophiolite suite (Malpas, Ch. 2, this is still carried on today (Fig. 1). The differences in chemical composition of serpentinized rocks volume) and occur in most fold-mountain belts are many and specimens come in a wide range of of the world. Serpentinized ultramafic rocks attractive solid and mixed colours, e. g. , red, "H4(MgFe hSi20 9, approximate composition) green, blue and black.

` The book will become a standard reference for all those interested in soil-plant relationships and will provide a stimulus for further research in this aspect of biogeography and geobotany. '

` ... to congratulate the editors on producing this excellent and exhaustive work on the ecology of world regions with serpentinized rocks. I am sure that this exciting and hiterhto neglected field will be well served and encouraged by the appearance of this important work. '
