“…Five of seven groups are represented in China (Table ). Within Carduinae, the close relationship of Shangwua and Xeranthemum was supported by our analysis and recent studies (Wang et al, ; Wang et al, ). The close relationships of Cousinia + ( Arctium + Schmalhausenia ) and Aucklandia + Frolovia , previously inferred by López‐Vinyallonga et al () and Wang et al (), separately, were also supported in our phylogenetic inferences (PP > 0.95; Fig.…”

“…The following rearrangements on the classification of Chinese Asteraceae were suggested: transferring the genera Leucomeris and Nouelia from the tribe Mutisieae to the tribe Hyalideae (Wunderlichioideae); Ainsliaea , Myripnois , and Pertya from the tribe Mutisieae to the tribe Pertyeae (Pertyoideae); Echinops from the tribe Echinopeae and Atractylodes , Carlina , and Tugarinovia from the tribe Carlineae to the tribe Cardueae (Carduoideae); Cavea from the genera incertae sedis to the tribe Gymnarrhenoideae (Gymnarrhenoideae), Centipeda from the genera incertae sedis to the tribe Athroismeae (Asteroideae); and Doronicum from the tribe Senecioneae to the tribe Doroniceae (Asteroideae). Other systematic studies related to Chinese Asteraceae (e.g., Liu, ; Anderberg et al, ; Gao & Liu, ; Funk et al ; Blöch et al, ; Fan et al ; Liu & Yang, ; Zhang et al, ; Wang et al, , 2013b; Li et al, ; Yuan et al, ) and The Phylogeny of Angiosperms (http://angio.bergianska.se/) were also considered here. Finally, we herein proposed an updated classification of Chinese Asteraceae at the generic level to reflect the recent phylogenetic and taxonomic changes (see Table , containing their placements in subfamilies, tribes, subtribes, and groups).…”

The sunflower family (Asteraceae) is the largest and the most diverse flowering plant family, comprising 24 000-30 000 species and 1600-1700 genera. In China, Asteraceae are also the largest family, with approximately 2336 indigenous species in 248 genera. In the past two decades, molecular phylogenetic analyses has contributed greatly to our understanding of the systematics of Asteraceae. Nevertheless, the large-scale analyses and knowledge about the relationships of Chinese Asteraceae at the generic level as a whole are far from complete due to difficulties in sampling. In this study, we presented a three-marker (rbcL, ndhF, and matK) phylogeny of Asteraceae, including 506 genera (i.e., approximately one-third of Asteraceae genera). The study sampled 200 Chinese genera (i.e., approximately 80% of Chinese Asteraceae genera). The backbones of the new phylogeny were largely congruent with earlier studies, with 13 subfamilies and 45 tribes recognized. Chinese Asteraceae were distributed in 7 subfamilies (Mutisioideae, Wunderlichioideae, Carduoideae, Pertyoideae, Gymnarrhenoideae, Cichorioideae, and Asteroideae) and 22 tribes (Mutiseae, Hyalideae, Cardueae, Pertyeae, Gymnarrheneae, Vernonieae, Cichorieae, Doroniceae, Senecioneae, Astereae, Anthemideae, Gnaphalieae, Calenduleae, Inuleae, Athroismeae, Helenieae, Coreopsideae, Neurolaeneae, Tageteae, Millieae, Eupatorieae, and Heliantheae). Chinese Asteraceae lacked 6 basal subfamilies and 23 tribes. Several previously ambiguous relationships were clarified. Our analyses also resolved some unplaced genera within Chinese Asteraceae. Finally, our phylogenetic tree was used to revise the classification for all genera of Chinese Asteraceae. In total, 255 genera, 22 tribes, and 7 subfamilies in China are recognized.

“…However, there is an alternate hypothesis: the change may have been in the opposite direction, from perennial to annual. In the Xeranthemum group, Amphoricarpos and Shangwua species grow in the Caucasus and East-Mediterranean mountains (Susanna & Garcia-Jacas, 2009) and the Qinghai-Tibetan Plateau and Himalayas (Wang et al, 2013), respectively, while the taxa from the other annual genera, Xeranthemum, Chardinia and Siebera, grow in open steppes in the Near and Middle East. Previous works have suggested that the ancestors of Xeranthemum and related genera are Shangwua and Amphoricarpos, both of them are perennials from conservative habitats (mountains).…”

“…The genus Xeranthemum L. is a member of the Xeranthemum group within subtribe Carduinae of the tribe Cardueae, together with Amphoricarpos Vis., Chardinia Desf., Siebera J. Gay (Susanna & Garcia-Jacas, 2009) and the newly described genus Shangwua Yu J. Wang, Raab-Straube, Susanna & J. Quan Liu (Wang et al, 2013). The genera of the group possess very characteristic pappus of the cypselae and the papery silver-white bracts of the capitulum.…”

Comparative anatomical and micromorphological analyses of root, stem, peduncle, leaf and inflorescence have been conducted on two Xeranthemum species, X. annuum and X. cylindraceum, by light microscopy (LM) and scanning electron microscopy (SEM). The main goal of the study was to examine the most important anatomical features and to find new valid taxonomic delimiting characters for the first time in both species. Regarding vegetative organs anatomy, the data obtained in this study indicated that both species possessed secondary tissues in the root, although these plants are annual. Also, stem anatomy was a typical of the Compositae family members, and anomocytic stomata type and dorsiventral leaf structure were present. On the involucral bracts surface crystals were noticeable, while highly developed multilayer sclerenchyma was present in the mesophyll. Palea anatomy was very similar to bract anatomy. Some floral features were as follows: lateral anther dehiscence, corolla composed of uniseriate epidermis and with a homogeneous parenchyma in the mesophyll, inferior ovary and anatropous ovule with basal placentation. The specific quantitative characters that were different between the examined species were emphasized. Some selected, well defined qualitative anatomical characters (e.g. shape of the young stem and peduncle cross-sections, type of glandular trichomes and cortical vascular bundles occurrence), on the basis of which the studied species were distinguishable, strengthen the taxonomy of the Xeranthemum genus and provide features for better identification of the taxa. This is the first study of the anatomy of Xeranthemum species and some of the characters found (secondary growth and dorsiventral leaves) points towards an adaptation of mesophilous ancestors to xeric habitats in Xeranthemum.

“…were difficult to reconstruct, mainly as a consequence of incomplete taxon sampling. Several studies (Raab‐Straube, ; Kita & al., ; Wang & al., ) have shown that Saussurea in its traditional circumscription (Lipschitz, ) was polyphyletic. For example, the species of Himalaiella and Lipschitziella were originally described within Saussurea , but have later been established as separate genera (Raab‐Straube, ).…”

Jurinea (Asteraceae: Cardueae) is a large Eurasian genus of about 180 species with centres of diversity in Central and Southwest Asia and the eastern Mediterranean. The genus includes many species with adaptations to xero-and chasmophytic habitats and comprises numerous endemics, especially in the Caucasus. Generic delimitations between Jurinea and closely related genera have been difficult to assess, as have the phylogenetic relationships with the genera Himalaiella, Jurinella and Lipschitziella, each of which has been suggested as congeneric with Jurinea. A molecular phylogenetic investigation at both the specific and the generic level to establish the generic delimitation of Jurinea and to evaluate the intergeneric relationships of the genus with other members of the Cardueae was hitherto lacking. In this study, we reconstruct the phylogenetic relationships between Jurinea and several closely related genera based on a representative taxon sampling using DNA sequence data of nuclear (ITS, ETS) and plastid DNA regions (trnK/matK, trnL-F). We also evaluate the infrageneric classification of Jurinea. Our results indicate that Jurinea is polyphyletic in its current circumscription, as the species J. gedrosiaca and J. cartilaginea are placed within the subtribe Centaureineae of the Cardueae. The rest of Jurinea is monophyletic and split into two major clades corresponding to the western and eastern range of the distribution area of the genus. The sister clade of Jurinea is composed of Himalaiella and Lipschitziella. Jurinella, which was segregated from Jurinea based on achene morphology, is congeneric with Jurinea. Like in other speciose Eurasian genera, the currently recognised sections do not reflect natural groups, whereas most clades found through molecular phylogenetic inference correlate with geographic patterns. A clade that exclusively comprises Caucasian endemics, including the narrow endemics of J. sect. Neobellae, was found. This clade represents an interesting study group for possible radiation events of Jurinea in the Caucasus.
