Species related to Paspalum denticulatum Trin. are studied systematically, including taxa traditionally placed in the informal group Livida of Paspalum L. The analysis demonstrates Livida to be an artificial group, without characters that delimit it from remaining groups within Paspalum; for this reason, its species are treated as ungrouped within subgenus delimit it from remaining groups within Paspalum; for this reason, its species are treated as ungrouped within subgenus delimit it from remaining groups within Paspalum; for this reason, its species are treated as ungrouped within subgenus delimit it from remaining groups within Paspalum; for this reason, its species are treated as ungrouped within subgenus informal group Livida of Paspalum L.
