It outlines species relationship using biogeography and level of ploidy as guides. The paper also provides an updated key and enumerates valid species, including synonymy. Species names found in the literature are listed alphabetically and matched with those given in the enumeration. By clarifying names for the different species, this paper aids persons interested in the wild relatives of rice.
