Hedysarum kalatensesp. nov. (Fabaceae) from Iran
Nordic Journal of Botany, 2012
Hedysarum kalatense Dehshiri sp. nov. (Fabaceae) is described and illustrated from Khorassan, Iran. It belongs to sect. Crinifera and is distinct among Iranian species. This species appears to be closely related to H. macranthum (Freyn & Sint.) B. Fedtschenko. The diagnostic characters, as well as a full description and a detailed illustration are provided. Hedysarum kalatense is evaluated as 'Vulnerable' (VU) according to IUCN red list criteria. Hedysarum L. belongs to Hedysareae of Fabaceae and has about 200 species mostly distributed in temperate regions of the Northern Hemisphere, with several species in the arctic regions (Vassiljeva 1987). Although the main center of diversity is in central Asia, there is another in North America, and the genus also occurs in Europe and the Mediterranean region (Polhill 1981, Yakovlev et al. 1996). Plants of the genus are perennial herbs, rarely semishrubs, and occur in various habitats, such as alpine and arctic meadows, stony grasslands, deserts or sea shores (Chori and Ohashi 2003). They show marked variation in the pods, which often bear features such as ribs, spines or prickles which have been used as diagnostic characters in sepa rating infrageneric taxa (Fedchenko 1902), and to distinguish closely related genera from Hedysarum (Polhill 1981). The flora of Iran is relatively rich in Hedysarum species. In 'Flora Iranica', 18 species (19 taxa), of which 10 species (11 taxa) are endemic to Iran, were treated (Rechinger 1984). Recently, several new Iranian taxa have been described in this genus (
Hedysarum garinense sp. nov. (Fabaceae: Hedysareae) from Iran
Nordic Journal of Botany, 2012
Hedysarum garinense Dehshiri & Maassoumi, a new species endemic to Iran, is described and illustrated. The new species belongs to sect. Crinifera Boiss. in Hedysarum L. (Fabaceae) and is distinct among Iranian species. This species is similar, and probably most closely related to H. nuratense M. Popov. The diagnostic morphological characteristics, as well as a full description, ecological characteristics, and distribution data are given. Hedysarum garinense is evaluated as ‘Vulnerable’ (VU) according to IUCN red list criteria.
A new species of Hedysarum (Fabaceae) in Iran and other new Hedysarum records
Botanical Journal of the Linnean Society, 2007
Hedysarum al-shehbazii, a new species endemic to Iran, is described and illustrated. This species belongs to Hedysarum section Multicaulia. It is confined to the western part of Iran (Kermanshah Province), and is known from a single population close to the Iraq frontier, although possibly also growing in the adjoining eastern part of Iraq. The conservation status of this species is 'vulnerable' according to World Conservation Union (IUCN) criteria. In addition, H. varium and H. syricum are reported as new records from a single gathering close to the Turkish frontier. Moreover, H. kotschyi and H. pogonocarpum are transferred from Hedysarum section Crinifera to Hedysarum section Multicaulia.
Notes on the taxonomy of Hedysarum (Fabaceae) in iran
2006
Although the main center of Hedysarum diversity is in Middle Asia, there is, however, another in N America, and the genus also occurs in Europe and the Mediterranean region (Yakovlev et al. 1996, Choi & Ohashi 2003). Plants of the genus occur in various habitats such as alpine and arctic meadows, strong grasslands, deserts or seashores (Choi & Ohashi 2003). Many species are also cultivated as fodder or for their ornamental value (Lock & Simpson 1991). They show marked variation in the pods, which often bear features — ribs, spines or prickles — which have been used as diagnostic characters in separating infrageneric taxa (Basiner 1845, Fedtschenko 1902), and to distinguish closely related genera from Hedysarum (Hutchinson 1964, Polhill 1981). Hedysarum was divided by de Candolle (1825) into two sections, Echinolobium and Leiolobium, based on pod morphology. Basiner (1845) proposed an infrageneric classification of the genus, which was adopted by Boissier (1872) and followed in essen...
TURKISH JOURNAL OF BOTANY, 2019
Hedysarum alamutense, a new species in the tribe Hedysareae DC. (Fabaceae), is described and illustrated. It belongs to the traditionally recognized Hedysarum L. section Multicaulia (Boiss.) B.Fedtsch., which extends over the West Alborz Mountains in northern Iran. This species is characterized by greenish stems and corolla persisting in fruiting stage and has mostly 1-2-jointed, unarmed, biconvex pods with short hairs becoming bald early, and flattened margins. Phylogenetic analyses of molecular data clearly unite this species with H. formosum Fisch. & C.A.Mey. ex Basin. The new species is characterized by 4 singleton nucleotide substitutions, suggesting it as a distinct taxon. Phylogenetic inferences are consistent with the interpretations of morphological features. Moreover, the lack of nucleotide variation among individual samples of H. formosum indicated that the species has not been diversified at the population level and reinforced our findings.
New plant records for Khorassan province, Iran, III
Annalen des Naturhistorichen Museums in Wien- …, 2010
Thirty-nine vascular plant taxa from 33 genera in 18 families are recorded for the first time from Khorassan Province, Iran. All taxa are angiosperms (30 dicotyledons and 9 monocotyledons). Eight o f these taxa are endemic to Iran. All specimens recorded here are deposited in FUMH and/or W, FAR, TARI. This contri bution is a continuation to the recently published papers on this province (G h a h r e m a n in e j a d & al. 2005; Joharchi & al. 2007, G h a h r e m a n in e j a d & al. 2009). In these four papers 459 species are recorded for the first time from this province. Furthermore, specimens from Khorassan representing new taxa or new records for Iran published in other papers are listed here. Therefore this series o f four papers serves as Supplement to Flora Iranica for the Khorassan flora.
New plant records for Khorassan province, Iran, V, with complementary notes to its flora
In the fifth and last contribution to the flora o f Khorassan 143 angiosperm plant taxa from 80 genera in 28 families are recorded for the first time. 21 o f these taxa are endemic to Iran. The specimens cited in this paper are deposited in several herbaria, i.e. BASU, FAR, FUMH, IRAN, K, MO, SUTH, TARI, TUH, W. This contribution is a continuation o f the recently published papers on this province (G h a h r e m a n i n e j a d & al. 2005, J o h a r c h i & al. 2007, G h a h r e m a n i n e j a d & al. 2010, J o h a r c h i & al. 2011). In the five papers (including the present) 586 species are reported for the first time from this province. Furthermore, as in the recently published part IV (J o h a r c h i & al. 2011), specimens from Khorassan representing new taxa or new records for Iran published in other papers are listed here to give a complete overview. This series o f five papers serves as Supplement to Flora Iranica treatments (R e c h i n g e r 1963-1999, 2001-2011) for the Khorassan province flora.

Alcea acaulis and A. fasciculiflora, two new records for the flora of Iran
2019
During several field trips to the western parts of Iran and after comparing the collected plants with other species of Alcea, we came across to following two specimens belonging to Malvaceae family which were found new to the flora of Iran from Ilam province. Alcea acaulis is distinguished from the other species in the genus by its very short stem. The second species, A. fasciculiflora, is morphologically similar to A. iranshahrii and A. ghahremanii which is distinguished by its leaf shape, flower color and indumentum features.BothAlcea acaulis and A. fasciculiflora are sparsely to densely covered by two types of glandular and non-glandular trichomes. The glandular trichomes are of clavate type and the non-glandular trichomes are divided into three types: simple, stellate and fascicled. The present paper, therefore, deals with taxonomic descriptions and relationships of the species, important diagnostic traits, micromorphological features of the trichomes, illustrations and the dist...
