Distribution of the genus Lithops
General distribution and rainfall zones
Above are three maps, the first one shows the general distribution of Lithops, the second shows the percentage of annual rainfall that falls in summer, and the third shows the average rainfall each of the areas receives annually. You can click on them to enlarge them.
Detailed distribution maps of the various species
For more information about the distribution of the various species, I have created a some maps with a lot more detail. These maps give a better idea of the distribution of the various species, and how their ranges often overlap with one another. The maps contain a lot of detail, and are in PDF format, so that you can zoom into certain areas to get a closer look. There are five different maps, all contained in one file. To view these maps you will need to have the Adobe Portable Document Reader installed on your computer. To download this software from the Adobe website, click here.
Once you have installed the software, or if you already have it installed, you can download the maps. The file is 1,7 Mb and might take a few seconds to download. To download, click here.
Ivan Boldyrev's Interactive Cole Locality Maps
Ivan Boldyrev has created an Interactive Cole Locality Map, allowing you to search for a specific Lithops using a variety of serach criteria. The results of your search are displayed on an interactive map, which you can zoom in and out of, as well as pan in all directions. It is a feature rich and versatile tool that one can use to great advantage when finding out more about the distribution and habitats of Lithops.
Cole locality data
Most of the information available to us today regarding Lithops, was the result of the dedicated work done by Professor Desmond Cole and his wife Naureen Cole. Over the years they have visited many localities where Lithops grow, and these localities were all assigned what are known as Cole numbers. At each locality, they collected specimen plants, and seeds. These were all assigned codes, and many of the Lithops we now find in cultivation have these Cole numbers attached. The numbers give us information about the original spot that the plants in question come from, and I have compiled a list of these plants. To see the full list, click here.
