	abstract = {Dicerandra, 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. 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.},

	abstract = {Phylogeny reconstruction at the species level, especially using organellar markers, is often complicated by problems such as incomplete lineage sorting and interspecific hybridization. Single-copy nuclear genes may be useful for these cases because they have higher mutation rates and are biparentally inherited. One plant group in which hybridization and incomplete lineage sorting have been proposed based on analyses of internal transcribed spacer (ITS) and plastid data is a clade of mints from the southeastern United States: Conradina and the related genera Dicerandra, Piloblepbis, Stacbydeoma, and Clinopodium (Lamiaceae). To clarify the phylogeny in this clade and investigate the possibility of incomplete lineage sorting and interspecific hybridization, we isolated three members of the nuclear GapC gene family and used two to reconstruct phylogeny. Separate phylogenetic analyses of the two GapC loci did not resolve species relationships. We then used two approaches to concatenate the two heterozygous GapC loci with ITS and plastid data sets from a previous study and carried out combined analyses. Trees resulting from the two concatenation approaches were similar in the resolution and support of generic relationships, but they differed drastically in resolution and support for relationships within Conradina. Conradina species are probably very recently derived, and it may be unreasonable to reconstruct species relationships in Conradina using DNA sequence data due to widespread hybridization or lack of coalescence. Rapidly evolving microsatellite data may be more useful for detecting hybridization and clarifying species boundaries in Conradina.},
