Molecular phylogenetic analyses of Dicerandra based on data from the nuclear and plastid genomes for all 13 taxa of the genus, identified two strongly supported clades, corresponding to the four annual and to the five perennial species of Dicerandra. However, the nuclear and plastid trees were incongruent in their placement of two perennial taxa, D. cornutissima and D. immaculata var. savannarum, perhaps due to ancient hybridization or to lineage sorting. Based on these analyses, the widespread D. linearifolia is not monophyletic, with populations of D. linearifolia var. linearifolia falling into either western or eastern clades. The western clade, comprising populations of D. linearifolia var. linearifolia and var. robustior, occurs in an area drained by rivers flowing toward the Gulf of Mexico, whereas the eastern clade, comprising populations of D. linearifolia var. linearifolia, D. densiflora, D. odoratissima, and D. radfordiana (i.e., all the annual species), occupies a region drained by rivers flowing to the Atlantic Ocean. Although this pattern of genetic differentiation between populations from these two river drainages has been documented in several animal species, it has not previously been reported for plants. A revised subgeneric classification is presented to reflect the annual and perennial clades.1 aOliveira, Luiz, O1 aHuck, Robin, B1 aGitzendanner, Matthew, A1 aJudd, Walter, S1 aSoltis, Douglas, E1 aSoltis, Pamela, S  uhttps://lamiaceae.myspecies.info/content/molecular-phylogeny-biogeography-and-systematics-dicerandra-lamiaceae-genus-endemic-002797nas a2200361   4500008004100000245013300041210006900174260000800243300001600251490000700267520153700274653001701811653002001828653001701848653001501865653002001880653001201900653001501912653003201927653001301959653002101972653000901993653001002002653001402012653001402026100002202040700001902062700002902081700002002110700002302130700002202153856026002175       2007                        eng d00aMolecular phylogeny, biogeography, and systematics of Dicerandra (Lamiaceae), a genus endemic to the southeastern United States'0 aMolecular phylogeny biogeography and systematics of Dicerandra L  cJan  a1017–10270 v943 aDicerandra, an endemic mint of the southeastern United States, comprises nine species, all of which are threatened or endangered and restricted to sandhill vegetation and a mosaic of scrub habitats.
