	abstract = {Hybridization and/or incomplete sorting of ancestral polymorphism are commonly implicated to explain discordant phylogenetic analyses of closely related species complexes. One genus in which these phenomena have been suggested to have played major roles based on phylogenetic data is Conradina, a genus of mints (Lamiaceae) endemic to the southeastern USA containing several endangered species. The goals of this study were to use microsatellite data to better understand patterns of genetic structure in Conradina, to test hypotheses of recent or ancient hybridization and incomplete lineage sorting, and to clarify species boundaries. Individuals from 55 populations representing all Conradina species were genotyped using 10 microsatellite loci. Analyses of the patterns of genetic structure in Conradina revealed a clear differentiation of populations following recognized species boundaries, indicating that species have diverged from one another genetically and interspecific hybridization has not occurred recently. Neither ancient hybridization nor incomplete lineage sorting is supported as the sole cause of species nonmonophyly, suggesting that both may have contributed to patterns found in phylogenetic trees; however, analyses of other types of data may be more appropriate to distinguish between these two hypotheses. Because all described species appear to be valid entities, the current listing status of most endangered species of Conradina is appropriate; however, populations of Conradina canescens are genetically differentiated into three groups, each of which may merit species status, and several recently discovered populations of Conradina in Dunn{\textquoteright}s Creek State Park in Florida are highly differentiated genetically and also appear to represent a new species.},

	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 = {Hesperozygis ringens Benth. (Lamiaceae) is an aromatic and medicinal plant, characterized by a high concentration of isopulegone; it is endemic to the mountains of southeast Rio Grande do Sul, Brazil, and currently is considered endangered. The present study evaluated the intra- and interpopulation genetic variability of H. ringens by means of RAPD and ISSR molecular markers. The results showed that H. ringens populations are genetically structured, with low gene flow between populations, confirming the fragmentation imposed by anthropic action. Populations from the two areas of occurrence are genetically different. Low intrapopulation variability and heterozygosity were detected, indicating genetic drift and inbreeding. Based on the data, conservation strategies are discussed.},

	abstract = {We report the isolation of microsatellite loci from three species in the genus Conradina (Lamiaceae). To ensure their utility for multiple species, loci were screened for amplification and variability in all six Conradina species; 11 loci demonstrated high levels of amplification and polymorphism in most species. These 11 loci were characterized in 20 individuals from one population of Conradina brevifolia; alleles per locus ranged from five to 15, and observed heterozygosity ranged from 0.30 to 0.90. These microsatellites will be used to clarify species limits, detect interspecific hybridization, and understand the partitioning of genetic variation in each species of Conradina.},
