A glossary of the characterisitcs of the Tetragonostachys
The attached PDF file is an illustrated glossary of the characteristics of these Selaginella species with correlation to the respective species possessing such attributes. It should provide an excellent source of information for those who have no idea what a sporophyll or an abaxial ridge is.
I would recommend printing out the 7 pages for future reference if you plan to check out these unique plants in the future.
