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.

However, because population genetic markers evolve rapidly, patterns of genetic structure based on these markers can often discern genetically isolated population groups, even when other markers, such as DNA sequences, can not. In this study, we analyzed patterns of genetic structure based on microsatellites in Conradina and identified a group of plants in Dunns Creek State Park (Putnam County, Florida) that are genetically divergent from all other described Conradina species. We then carried out a mor- phological study that revealed several unique characters in these populations, most notably unicellular hairs, epidermis features, and larger calyces. Because these populations are genetically and morphologically diagnosable from all other Conradina species, we thus consider them to be specifically distinct, and name this taxon Conradina cygniflora. Conradina cygniflora is endemic to Dunns Creek State Park in south- central Putnam County, Florida, where it occupies eight tightly-clustered sites that probably form around two to four self-sustaining popula- tions. Due to its extremely limited geographic distribution and few individuals, we recommend that Conradina cygniflora be listed as federally endangered.1 aEdwards, Christine, E1 aJudd, Walter, S1 aIonta, Gretchen, M1 aHerring, Brenda  uhttps://lamiaceae.myspecies.info/content/using-population-genetic-data-tool-identify-new-species-conradina-cygniflora-lamiaceae-new
