Polygonum khajeh-jamali(Polygonaceae), a New Species from Iran

What isAtraphaxisL. (Polygonaceae, Polygoneae): cryptic taxa and resolved taxonomic complexity instead of the formal lumping and the lack of morphological synapomorphies

“…All accessions of A. ovczinnikovii are fairly distinct in habit from the members of Polygonum section Spinescentia , which are dwarf, cushion-shaped caespitose undershrubs, shrubs, or perennials, some with prickly shoots and branchlets ( Jaubert & Spach, 1844–1846 ; Boissier, 1846 ; Boissier, 1879 ; Gross, 1913 ; Mozaffarian, 1988 ; Mozaffarian, 2012 ; Khosravi & Poormahdi, 2008 ; Tavakkoli et al, 2015 ). Polygonum salicornioides is a cushion-shaped dwarf undershrub with the shoots not lignified and less prickly ( Fig.…”

“…This minutely tuberculate surface is peculiar to the Polygonum sect. Spinescentia ( Boissier, 1846 ; Boissier, 1879 ; Gross, 1913 ; Mozaffarian, 2012 ; Khosravi & Poormahdi, 2008 ; Tavakkoli et al, 2015 ). The exception is Polygonum botuliforme with smooth shiny achenes ( Mozaffarian, 1988 ).…”

“…Indeed, the members of Polygonum section Spinescentia with the perianth divided to 1/2–3/4 in five equal-sized segments ( Boissier, 1846 ; Boissier, 1879 ; Gross, 1913 ; Khosravi & Poormahdi, 2008 ; Mozaffarian, 1988 ; Mozaffarian, 2012 ) formally resemble some Atraphaxis species that were originally described in the genus Polygonum and later circumscribed with Atraphaxis as members of Atraphaxis s.str. clade ( Yurtseva et al, 2010 ; Schuster, Reveal & Kron, 2011b ).…”

“…For the analysis of perianth morphology of Polygoneae , personal observations (summarized in Tables 1 and S4 ), and reference data (summarized in Table S5 ) on the genera Polygonum and Atraphaxis ( Yurtseva et al, 2010 ; Yurtseva et al, 2012a ; Yurtseva et al, 2012b ; Yurtseva, Severova & Bovina, 2014 ), Fallopia, Reynoutria ( Brandbyge, 1993 ; Ronse De Craene & Akeroyd, 1988 ), Knorringia ( Hong, 1989 ); Muehlenbeckia ( Brandbyge, 1992 ), Duma ( Brandbyge, 1992 ; Schuster, Wilson & Kron, 2011a ), Polygonum and Polygonella ( Horton, 1963 ; Ronse De Craene & Akeroyd, 1988 ; Ronse Decraene, Hong & Smets, 2004 ), Polygonum sect. Spinescentia ( Jaubert & Spach, 1844–1846 ; Boissier, 1846 ; Boissier, 1879 ; Meisner, 1857 ; Gross, 1913 ; Mozaffarian, 1988 ; Mozaffarian, 2012 ; Khosravi & Poormahdi, 2008 ; Tavakkoli et al, 2015 ) were used.…”

The evolution of a new scene for botanical publication from the Nordic countries

“…It is therefore most encouraging to see that almost 100 new taxa from throughout the world was published in 2008. Most novelties are vascular plants from Turkey (Aksoy et al 2008, Dogan et al 2008, Dönmez 2008, Eker and Koyuncu 2008, Gemici et al 2008, Ilçim 2008, Ilçim et al 2008, Teksen and Aytaç 2008, Uysal 2008, Yaprak and Yurdakulol 2008, Zielinski and Tomaszewski, 2008), Iran (Hamdi et al 2008, Pakravan 2008, Khosravi and Poormahdi 2008, Ranjbar et al 2008), India (Baruah and Nath 2008, Raole and Desai 2008), China (Cong et al 2008, Gao and Zhang 2008, Häkkinen and Wang 2008, Jiang and Liu 2008, Jin et al 2008, Li and Wang 2008, Lidén and Van De Veire 2008, Qiao and Zhang 2008, Shi et al 2008b, Song et al 2008, Tian et al 2008, Wang et al 2008, Wei et al 2008, Xiang and Peng 2008, Xiang et al 2008, Yi et al 2008, Zhang and Li 2008, Zhang et al 2008a,b,c, Zhou et al 2008a) and south east Asia (Ngamriabsakul 2008, Turner and Saunders 2008), demonstrating the botanical richness and the great need for basic taxonomic research in these regions. For example, in one single paper, Vermeulen (2008) described 38 new species of the orchid genus Bulbophyllum from New Guinea alone.…”
