In our latest paper, using morphological, genetic and environmental data, we evaluated the demographic history and the species delimitation of Zamia loddigesii, Z. splendens and Z. katzeriana. Previously, Z. katzeriana was thought to be originated from events of hybridization between the other two species. Here, we found that it was not the case: Z. katzeriana is a taxonomically well-delimited species that was not originated from hybridization. Also, we report and discuss for the first time a case of hybridization in cycads between Z. loddigesii and Z. splendens.
