Maps 
There are seven maps altogether. 

In conjunction with the maps a list may be found at the end of the species descriptions, showing the numbers with relevant species. A few species ignore the restrictions of boundaries and appear on two maps! 

Acknowledgements

I would like to mention here that it was Karel Knize of Lima who amended my original primitive attempts to obtain approximate locations. My heartfelt thanks go to him for taking the trouble and trying to translate my English into his German. Needless to say. I had problems translating his German into my English! It is probable that Ritter has found various species in other localities not mentioned here.

My thanks also go to Louise Teare for prodding us South Australians into studying the cacti of South America. and to Penny Oglesby for her beautiful drawings.
