Dated Phylogeny of Section (Fabaceae) and Allied Taxa in the Hypoglottis Clade.

The subgenus Bunge, which consists of several sections, is one of the taxonomically most complicated groups in the genus. The section Bunge belongs to this subgenus and is a significant element of the Irano-Turanian floristic region. A molecular phylogenetic analysis of this section and its closely related taxa using nuclear ribosomal DNA internal transcribed spacers (ITS) and external transcribed spacer (ETS) regions as well as plastid K sequences were conducted.

Variations in Structure among Androecia and Floral Nectaries in the Inverted Repeat-Lacking Clade ().

The vast majority of highly valuable species of the Leguminosae in temperate latitudes belong to the Inverted Repeat-Lacking Clade (IRLC). Despite having a generally conserved monosymmetric floral morphology, members of this group are remarkable with a pronounced diversity of floral sizes, modes of staminal fusion, and pollination strategies. This paper examined androecia and floral nectaries (FNs) in selected genera of the IRLC.

Molecular phylogeny and divergence times of Astragalus section Hymenostegis: An analysis of a rapidly diversifying species group in Fabaceae.

The taxa of Astragalus section Hymenostegis are an important element of mountainous and steppe habitats in Southwest Asia. A phylogenetic hypothesis of sect. Hymenostegis has been obtained from nuclear ribosomal DNA internal transcribed spacer (ITS) and plastid ycf1 sequences of up to 303 individuals from 106 species, including all 89 taxa currently assigned to sect.

Molecular Phylogeny and Morphological Analysis Support a New Species and New Synonymy in Iranian Astragalus (Leguminosae).

As a result of a taxonomic and phylogenetic revision of Astragalus section Hymenostegis we identified a new species of Astragalus from northwestern Iran, namely A. remotispicatus spec. nov.

Leaf epidermal features of Salix species (Salicaceae) and their systematic significance.

Premise Of The Study: The classification of the genus Salix has historically been intrinsically difficult due to its propensity toward plasticity and high variation in diagnostic morphological characters. We investigated leaf epidermal characteristics, focusing on the stomatal apparatus because it may provide critical insights into the evolution and taxonomy of Salix and its closely related genera.

Methods: Light microscopy was used to examine the leaf epidermal features in 32 taxa of Salix.

Micromorphology of glandular hairs, biological activity and composition of the essential oil of Tanacetum fisherae (Asteraceae-Anthemideae) from Iran.

The essential oil was obtained from the aerial flowering parts of Tanacetum fisherae, a new record from Iran, by hydrodistillation and analyzed by GC and GC-MS. Eleven components representing 99.9% of the total oil were identified.
