Three new species of Onosma L. (Boraginaceae) from Iran

Abstract

In this paper, we present some important findings in Onosma sect. Onosma. Data were collected during several surveys in western and northwestern Iran. Three new species were discovered and are illustrared here, namely O. sheidaii sp. nov and O. azarbaidjanensis sp. nov (in subsect. Haplotricha) and O. mozaffariani sp. nov. (In subsect. Heterotricha). An extensive review of literature and the comparative study with specimens kept in 14 Asiatic and European herbaria lead to the assessment of their independent, specific status based on both macro and micro‐ morphological characters, which are discussed in respect to possibly closely allied species.

Molecular phylogeny and divergence times of Onosma (Boraginaceae s.s.) based on nrDNA ITS and plastid rpl32‐trnL(UAG) and trnH–psbA sequences

“…Simultaneously, Fedorov (2001) in Flora of Russia, accepted two subsections: Onosma and Haplotricha. In Iran, Onosma is represented by 46 species (Khatamsaz 2002, Attar and Joharchi 2006, Attar and Hamzehee 2007, Mehrabian et al 2013, 2015.…”

Onosma moussavi sp. nov (Boraginaceae) from Zagros Mountain (s), Iran

“…There are several taxonomical complexes (Kolarčik et al., and ) and some ambiguity in identification and differentiation of the taxa (Riedl et al. ; Mehrabian et al., ) that has resulted from interspecific hybridization (Kolarčik et al., and ). In addition, lack of efficient diagnostic keys and overlaps in morphological characteristics (Kolarcik et al., 2010) have created numerous challenges to the systematic of the genus.…”

Onosma maculata sp. nov. (Boraginaceae) from Iran

“…During plant exploration trips in Iran, the authors collected specimens of Onosma. After critical studies some of them were found to differ from all the known species of the genus (Boissier 1879, Riedl 1967, 1979, Popov 1974, Khatamsaz 1992, Ranjbar and Almasi 2013, 2014). These latter are described and illustrated as a new species here.…”

“…The genus Onosma comprises about 230 species, mainly distributed in southwest Asia, the Mediterranean region and temperate Europe (Boissier , Riedl , Peruzzi and Passalacqua , Binzet et al , Mehrabian et al , Ranjbar and Almasi ). In ‘Flora Iranica’ (Riedl ) 38 species from Iran were treated under the three sections Protonosma Popv., Podonosma (Boiss.)…”

“…Gürke and Onosma. Since the genus was revised for 'Flora Iranica', 7 new species and 6 new records have been published for Iran (Khatamsaz 1992, Ghahreman and Attar 1996, Attar and Joharchi 2006, Attar and Hamzeh'ee 2007, Ranjbar and Almasi 2013, 2014. The sectional delimitation of the genus is still not settled and the problem has been made more confusing by a lack of consensus on the correct placement of the type species of the genus.…”
