“…However, our results did not recover a monophyletic Caraganeae (Figs 1, 2). Similarly, the previously expanded delimitation of Hedysareae sensu Lock (2005; also see Cardoso et al 2013), which included the genera of subtribe Caraganinae and tribe Hedysareae sensu Amirahmadi et al (2014), is not confirmed herein (Figs 1, 2). …”

“…Morphologically, this subtribe differs from Chesneyinae by several characters, including habit (shrubs vs. perennial herbs or subshrubs), leaf type (paripinnate [except for Calophaca ] vs. imparipinnate) and nerve type on wing petals (pinnate vs. palmate except for Chesneya ; Lock 2005; Ranjbar et al 2014; Duan et al 2015). Caraganinae is also distinct from Hedysareae (as delimited in Amirahmadi et al 2014 and Duan et al 2015) based on the following morphological characters: shrubs, rarely small trees; paripinnate, rarely imparipinnate leaves ( Calophaca ); solitary flowers, or a few flowers in fascicles, rarely forming a raceme; pods cylindric, rarely compressed, glabrous or hairy, with dehiscent and twisted valves (except for Halimodendron ; Polhill 1981; Liu et al 2010b). Caraganinae is also related to the Astragalean clade; yet due to the morphological diversity of the latter, there are few diagnosable features to differentiate the Astragalean clade from Caraganinae, except for the twisted valves of Caraganinae ( Calophaca and Caragana ).…”

Based on sequence data of nuclear ITS and plastid matK, trnL-F and psbA-trnH markers, the phylogeny of the subtribes Caraganinae and Chesneyinae in tribe Caraganeae was inferred. The results support the monophyly of each of the subtribes. Within subtribes Caraganinae, Calophaca and Halimodendron are herein transferred into Caragana to ensure its generic monophyly. The subtribe Chesneyinae is composed of four well-supported genera: Chesneya, Chesniella, Gueldenstaedtia and Tibetia. Based on phylogenetic, morphological, distributional and habitat type evidence, the genus Chesneya was divided into three monophyletic sections: Chesneya sect. Chesneya, Chesneya sect. Pulvinatae and Chesneya sect. Spinosae. Chesneya macrantha is herein transferred into Chesniella. Spongiocarpella is polyphyletic and its generic rank is not maintained. The position of Chesneya was incongruent in the nuclear ITS and the plastid trees. A paternal chloroplast capture event via introgression is hypothesized for the origin of Chesneya, which is postulated to have involved the common ancestor of Chesniella (♂) and that of the Gueldenstaedtia – Tibetia (GUT) clade (♀) as the parents.

Oxytropis and Astragalus represent one of the largest angiosperm genera complexes. Although phylogenetic studies of this complex exist, the evolutionary relationships among Astragalus and Oxytropis species sharing similar habitats in the Old World have not been studied in detail. The phylogenetic relationships among 13 Oxytropis and 56 Astragalus species native to Turkey were inferred from nucleotide sequence variations in the nuclear ribosomal internal transcribed spacer (ITS) and chloroplast maturase-like protein (matK) gene regions. In addition to our samples, 36 Oxytropis ITS and 6 Oxytropis matK sequences were retrieved from GenBank and included in the analysis. Phylogenies derived from a maximum likelihood analysis of the sequences indicated that Oxytropis and Astragalus genera are more likely monophyletic. However, the results suggest that New World Oxytropis species did not evolve by a single adaptive radiation in the genus, but rather from different Old World lineages. The genetic divergence between genera was less when the matK region was analyzed. Although the Oxytropis species did not show high genetic diversity, one subcluster of the genus was always distinctly separated in both trees. This subcluster was formed by the species Oxytropis engizekensis Duman & Vural and O. persica Boiss., which are also regarded as synonyms in regard to several morphological characters of the genus.

“…According to Hedge, Sartoria differs from Onobrychis in the three ovulate ovary and 2-3-seeded, large, ovateoblong unarmed fruit; from Hedysarum it is distinguished by the non-lomentoid fruit, small corollas and dwarf habit. According to phylogenetic analysis of the tribe Hedysareae using chloroplast trnL-F sequences, Amirahmadi et al (2009) declared that the genus Sartoria, endemic to Turkey, was nested within Eurasian Hedysarum. Also, the seed storage protein profiles results showed that Sartoria and Hedysarum are closer to each other than they are to Onobrychis (Arslan and Ertuğrul 2010).…”

Nine chromosome counts in several genera of the tribe Hedysareae from Turkey, six species of Onobrychis, two species of Hedysarum and one species of Sartoria, were reported and all karyotypes were prepared. Six of them are new. One of the other three reports is a confirmation of polyploidy, another report is a confirmation of chromosome count and the last report is a confirmation of both chromosome count and karyotype morphology. Except for karyotype of O. altissima, all karyotypes were presented in this study first.
