“…Buddlejaceae and Scrophulariaceae have long been accepted as close families (Dahlgren 1983). When a restricted set of Buddlejaceae is considered (Buddleja, Emorya, Gomphostigma and Nicodemia) in molecular phylogenetic studies, both families fall in the same clade, with strong support (Bremer et al 2001, Oxelman et al 1999. A third family, Myoporaceae, was added to the clade by a three-gene reconstruction (Olmstead et al 2001).…”

The non-coding trnE-trnT intergenic spacer of cpDNA was analyzed to assess the nucleotide sequence polymorphism of 16 Solanaceae species and to estimate its ability to contribute to the resolution of phylogenetic studies of this group. Multiple alignments of DNA sequences of trnE-trnT intergenic spacer made the identification of nucleotide variability in this region possible and the phylogeny was estimated by maximum parsimony and rooted with Convolvulaceae Ipomoea batatas, the most closely related family. Besides, this intergenic spacer was tested for the phylogenetic ability to differentiate taxonomic levels. For this purpose, species from four other families were analyzed and compared with Solanaceae species. Results confirmed polymorphism in the trnE-trnT region at different taxonomic levels.

“…Indeed, analyses using rbcL sequence data showed that Carlemannia is sister to Jasminum (Oleaceae), with weak bootstrap support (64%, Savolainen et al 2000). Analyses using morphological and rbcL and ndhF sequence data showed that Carlemannia and Silvianthus are sister genera, though their relationship is uncertain within Lamiales (Bremer et al 2001). APG II (2003) results for these studies place the Carlemanniaceae in the Lamiales.…”

“…2). The tree showed that the Carlemanniaceae are monophyletic, as reported by Bremer et al (2001), and sister to the Oleaceae in the Lamiales, as indicated by Savolainen et al (2000). The Caprifoliaceae, in which Carlemannia and Silvianthus had previously been placed, are not positioned close to these species.…”

“…It is possible that if more families of the Lamiales were included in the analyses, the position of the Carlemanniaceae might change. However, an expanded analysis, including all the families, also showed that the Carlemanniaceae are positioned nearest to Oleaceae (Bremer et al 2001). Significantly, within the genera of Oleaceae, Myxopyrum (Myxopyreae) (x = 11) is basally divergent and is sister to the rest of the family, followed by the Fontanesieae-Jasmineae clade (x = 11, 13), and by the clade composed of genera of Oleeae (x = 23) (for chromosome data see IPCN 2007).…”

“…Although both Carlemannia and Silvianthus were first included in the Rubiaceae (Bentham 1853;Hooker 1868;Schumann 1891), they have usually been placed in the Caprifoliaceae (Solereder 1893;Hutchinson 1926Hutchinson , 1967Wagenitz 1964;Cronquist 1981) or in a separate family, Carlemanniaceae (Airy Shaw 1965;Takhtajan 1997). Recent phylogenetic analyses have consistently suggested the assignment of Carlemanniaceae to the Lamiales (Savolainen et al 2000;Bremer et al 2001). Indeed, analyses using rbcL sequence data showed that Carlemannia is sister to Jasminum (Oleaceae), with weak bootstrap support (64%, Savolainen et al 2000).…”

The Carlemanniaceae comprises two small genera that are restricted to East Asia: the Carlemannia and Silvianthus. These genera were previously placed in the Rubiaceae or Caprifoliaceae, but are now considered a distinct family that is probably related to the Oleaceae in the Lamiales. The family is still poorly understood with respect to its morphological characteristics. Here, we present the first report of the chromosome numbers of the family using species from both genera, i.e., Carlemannia tetragona, Silvianthus bracteatus ssp. bracteatus, and S. bracteatus ssp. clerodendroides. The species were compared with the chromosome numbers of Oleaceae and associated families using a Bayesian tree that was generated from rbcL and ndhF sequence data from Genbank. C. tetragona had 2n = 30 (x = 15), whereas the two subspecies of Silvianthus had 2n = 38 (x = 19). Comparisons of chromosome numbers support the distinctness of the Carlemanniaceae, not only from the Oleaceae (x = 11, 13, 23), but also from the Tetrachondraceae (x = 10, 11), a family that is possibly related to the Carlemanniaceae and/or Oleaceae in the Lamiales. The notable difference in chromosome number between Carlemannia and Silvianthus, as well as the differences in other characteristics (pollen, seed, and fruit morphology), suggests that the family split early in its evolution.
