“…Teutliopsis Dumort. : Sukhorukov 2006;Žerdoner Čalasan et al 2022), which are deposited at MW, an unusual plant was found that readily differs from this species by its (sub) opposite leaves with crenate blades and by the leaf venation with remarkable chlorenchyma stripes that is peculiar for the atriplicoid Kranz anatomy. These features indicate that this plant is actually A. flabellum, a desert species from Central Asia, Iran and Afghanistan, which has never been reported for Russia (Lomonosova 1992;Sukhorukov 2006).…”

For a long time, the systematics of Atriplex was based solely on morphological characters and leaf anatomy. The latest worldwide phylogenetic study of Atriplex significantly improved our knowledge about the relationships within the genus, but a new classification has not been put forward thus far. Here we re-evaluate the taxonomy of C4-species of Atriplex that are native to Russia. Seven species are classified into two sections, A. sect. Obione (incl. A. sect. Sclerocalymma, syn. nov.) (A. altaica, A. centralasiatica, A. rosea, A. sibirica, and A. sphaeromorpha), and A. sect. Obionopsis (incl. A. sect. Psammophila, syn. nov.) (A. fominii and A. tatarica). Although the majority of Eurasian C4-species have similar morphology, leafy inflorescence is a typical character for A. sect. Obione. The members of A. sect. Obionopsis are characterised mostly by aphyllous inflorescences, but some species (A. laciniata, A. pratovii, and A. tornabenei) have leafy inflorescences. Geographically, almost all members of A. sect. Obione are confined to Central Asia, although A. rosea is a typical Mediterranean element and A. argentea occurs in North America. The representatives of A. sect. Obionopsis are distributed mostly in the Mediterranean and the Irano-Turanian floristic region. The alien status of A. rosea, A. sibirica and A. tatarica is discussed. Atriplex flabellum, a desert species from the Irano-Turanian region, is reported for the first time from Russia (Yamalo-Nenets Autonomous District, North Siberia) as a casual alien. This species occupies a phylogenetic position distant from both aforementioned sections. An identification key to all C4-species of the genus growing in Russia is given, and a sectional checklist with updated nomenclature and revised synonymy is provided.

C₄ is one of three known photosynthetic processes of carbon fixation in flowering plants. It evolved independently more than 61 times in multiple angiosperm lineages and consists of a series of anatomical and biochemical modifications to the ancestral C3 pathway increasing plant productivity under warm and light‐rich conditions. The C4 lineages of eudicots belong to seven orders and 15 families, are phylogenetically less constrained than those of monocots and entail an enormous structural and ecological diversity. Eudicot C4 lineages likely evolved the C4 syndrome along different evolutionary paths. Therefore, a better understanding of this diversity is key to understanding the evolution of this complex trait as a whole. By compiling 1207 recognised C4 eudicots species described in the literature and presenting trait data among these species, we identify global centres of species richness and of high phylogenetic diversity. Furthermore, we discuss climatic preferences in the context of plant functional traits. We identify two hotspots of C4 eudicot diversity: arid regions of Mexico/Southern United States and Australia, which show a similarly high number of different C4 eudicot genera but differ in the number of C4 lineages that evolved in situ. Further eudicot C4 hotspots with many different families and genera are in South Africa, West Africa, Patagonia, Central Asia and the Mediterranean. In general, C4 eudicots are diverse in deserts and xeric shrublands, tropical and subtropical grasslands, savannas and shrublands. We found C4 eudicots to occur in areas with less annual precipitation than C4 grasses which can be explained by frequently associated adaptations to drought stress such as among others succulence and salt tolerance. The data indicate that C4 eudicot lineages utilising the NAD‐ME decarboxylating enzyme grow in drier areas than those using the NADP‐ME decarboxylating enzyme indicating biochemical restrictions of the later system in higher temperatures. We conclude that in most eudicot lineages, C4 evolved in ancestrally already drought‐adapted clades and enabled these to further spread in these habitats and colonise even drier areas.
