Abstract:The composition of many Chenopodiaceae genera in different parts of Himalaya and Tibet has been insufficiently known or contradictory. A revision of the family in Himalaya including Bhutan, Nepal, parts of India (Himachal Pradesh, Jammu and Kashmir, Sikkim and Uttarakhand) and Tibet (Xizang, China) is presented for the first time. Altogether, 57 species from 20 genera are reported, including three species new to science (Agriophyllumtibeticum, Salsolaaustrotibetica and Salsolahartmannii). Atriplexcentralasiati… Show more

“…s.l., with many species transferred from Chenopodium to Dysphania by Mosyakin & Clemants (2002, 2008), Verloove & Lambinon (2006) and Uotila (2013). Further investigations based on morphological and carpological data allowed the description of new species of Dysphania from the Himalayas and Tibet (Sukhorukov, 2012b, 2014; Uotila, 2013; Sukhorukov & al., 2015), and Australia (Dillon & Markey, 2017), and to confirm or contradict the species status of some taxa (Sukhorukov & al., 2018b, 2019a,b). To date, Dysphania is one of the largest genera in Chenopodioideae, comprising ca.…”
After a rather turbulent taxonomic history, Dysphanieae (Chenopodioideae, Amaranthaceae) were established to contain five genera, four of which are monospecific (Cycloloma, Neomonolepis, Suckleya, Teloxys) and geographically restricted, and the fifth genus, Dysphania, having a nearly worldwide distribution and comprising ca. 50 species. This study investigates the phylogeny, biogeography and taxonomy of Dysphanieae. We studied specimens from 32 herbaria to infer morphological differences and distribution areas of the species and sampled 121 accessions representing 39 accepted species of the tribe for molecular phylogenetic analyses. The molecular phylogeny tested generic relationships of the tribe and infrageneric relationships of Dysphania on the basis of two plastid DNA markers (atpB‐rbcL spacer, rpl16 intron) and two nuclear ribosomal markers (ETS, ITS) and was also used for an ancestral area reconstruction with BioGeoBEARS. Three of the monospecific genera (Neomonolepis, Suckleya, Teloxys) form a basal grade and appear to be relictual lineages of the tribe, while Cycloloma is nested within Dysphania. The ancestral area reconstruction favors a widespread ancestry for Dysphanieae, and the relictual lineages in Asia (Teloxys) and North America (Neomonolepis, Suckleya) might be explained by a wide distribution across Beringia during the Late Oligocene/Early Miocene. Dysphania likely originated in North America; however, the simultaneous diversification into three major clades, an Asian/African, an American and an Australian/African clade, indicates a widespread ancestor at the crown node of Dysphania. Our taxonomic revision results in four accepted genera in Dysphanieae, Dysphania, Neomonolepis, Suckleya and Teloxys. The sectional subdivision for Dysphania is revised. We subdivide the genus into five sections, D. sect. Adenois (13 spp.), D. sect. Botryoides (10 spp.), D. sect. Dysphania (17 spp.), D. sect. Incisa (2 spp.) and D. sect. Margaritaria (4 spp.); three strongly deviating species remain unplaced and need further attention.
“…Zhu and Zhang (2016) and Zhu and Sanderson (2017) recognized additional segregate genera Roubieva Moq. and Neobotrydium Moldenke; however, it is not justified from both phylogenetic and morphological viewpoints (see comments in Sukhorukov et al, 2016aSukhorukov et al, , 2019 because both Roubieva and Neobotrydium are phylogenetically deeply nested in Dysphania. The new genus Carocarpidium S.C.Sand.…”

“…Chenopodium ficifolium is widespread in temperate to subtropical regions of Eurasia, from Atlantic Europe in the west through southern Asia to the East Asian region (Aellen, 1929(Aellen, , 1960(Aellen, -1961Uotila, 1997Uotila, , 2001aPaul, 2012;Mosyakin, 2016;Clemants, 2006;Sukhorukov et al, 2016bSukhorukov et al, , 2019etc.). The species is also known as occasionally introduced in many other regions of the world, such as North America Mosyakin, 2016, and references therein), Australia (Wilson, 1984; mentioned as not confirmed), and New Zealand (Kirk, 1896;Allan, 1940;Sykes, 1982;Webb et al, 1988, reported as casual).…”
Historical records and the current status of Chenopodium ficifolium (Chenopodiaceae) in New Zealand are considered. This species of Eurasian origin was and still is occasionally reported in New Zealand as a casual alien since its supposedly first record by Kirk in 1896, who found the species in 1892 in the port of Wellington on a ballast heap. At least seven reliable collections / records are known from locations ranging from the North Island (Auckland and Wellington) to the South Island (Christchurch), and one of the southern Titi Islands. However, the actual distribution of the species in New Zealand is probably underestimated because of its similarity to C. album. Probably C. ficifolium was initially introduced to New Zealand much earlier than 1892, as evidenced by the herbarium specimen collected by J. Everard Home in the 1840s. That specimen was recently found in the Turczaninow historical herbarium at the National Herbarium of Ukraine (KW); it is one of many other historical specimens at KW that were collected in New Zealand by Home, A. Cunningham and R. Cunningham in the first half of the 19 th century. Most probably, Turczaninow received these New Zealand specimens from the Royal Botanic Gardens Kew in exchange for his Siberian or other collections. We expect that a thorough revision of New Zealand specimens in the Turczaninow herbarium at KW may bring important and interesting results not only on native plants (including type specimens), but also for non-native species introduced during the early stages of the European colonization, which will document their earliest stages of expansion in New Zealand.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
