Astragalus sect. Dissitiflori (Fabaceae) in Iran

Abstract

Two new species, Astragalus ghahremaninejadii and A. kharvanensis are described from Iran and illustrated. They belong to A. sect. Dissitiflori, which contains species with bifurcate hairs. The first is similar to A. pendulinus, A. baldschuanicus, A. kustanaicus and properly A. marguzaricus and only known from a single collection close to the Turkmenistan frontier. The second shows morphological similarities with A. dendroproselius especially A. viridis. Also A. dendroproselius is reported as a new record for the flora of Iran.

Molecular systematics of some bifurcate hairy sections in <i>Astragalus</i> L. (Fabaceae) as inferred from nuclear and chloroplast DNA sequences

“…Cremoceras Bunge and A. sect. Trachycercis Bunge (Ranjbar 2004). This idea is also supported partially with molecular evidences (Kazempour Osaloo et al, 2005;Sheikh Akbari et al, 2012b).…”

“…Astragalus sect. Dissitiflori DC is one of the largest sections among bifurcate hairy Astragalus, with more than 150 species in the world (Ranjbar, 2004) and about 20 species in Iran . Ghahreman et al, (1996) transferred A. viridis Bunge and A. dendroproselius Rech.…”

Astragalus sect. Trachycercis (Fabaceae) in Iran

“…This sub‐genus with more than 800 species has its main center of diversity in central (Yakovlev et al 1996) and southwest Asia (Ranjbar 2007a, 2007b). In the course of the work on Astragalus , the majority of bifurcate‐haired species known from Iran have been (Rechinger et al 1961, 1969, Ghahreman et al 1996, Maassoumi and Ranjbar 1998, Ranjbar and Maassoumi 1998, Maassoumi et al 1999, 2000, Podlech 2001, Podlech and Sytin 2002, Podlech and Maassoumi 2003, Podlech and Zarre 2003, Ranjbar and Karamian 2003, 2004, Zarre et al 2005, Karamian and Ranjbar 2005b, Ranjbar et al 2005, 2007a, 2007b, Ranjbar 2007a, 2007b).…”

Molecular evidence for reticulate speciation in Astragalus (Fabaceae) as revealed by a case study from sect. Dissitiflori

“…de Candolle in 1825. Later, Bunge (1868) introduced the same section under the name of Xiphidium, unaware that this had already been done by de Candolle (Ranjbar 2004). The lectotype of this section is Astragalus varius S.G.Gmel.…”

“…In fact, sect. Dissitiflori is the largest bifurcate haired Astragalus section (Ranjbar 2004). Species of this section are morphologically characterized by imparipinnate leaves, loose racemes, and shortly pedicellate flowers.…”
