In addition, the geographical distribution and ecology of the species belonging to this section are discussed.

A taxonomic revision of Centaurea section Acrocentron (Asteraceae) in Iran

“…As can be seen from recent papers in this journal (e.g. Karamian & Ranjbar, 2005; Zarrei et al ., 2007), there is considerable active taxonomic research on the Iranian flora. This includes the genus Centaurea L. (with approximately 600 species around the world, one of the largest genera in the family).…”

A new species of Hedysarum (Fabaceae) in Iran and other new Hedysarum records

This genus contains about 200 species, is a large genus within the tribe Hedysareae distributed in the temperate to boreal regions of the Northern Hemisphere (Vassiljeva, 1987).…”

The first record of Astragalus sect. Aegacantha (Fabaceae) in Iran

“…Asfragalus L. (Fabaceae) is generally considered as the largest genus of vascular plants with an estimated number of 2500-3000 species (Lock & Simpson 199 1 ;Mabberley 1997;Maassoumi 1998, Ranjbar & Karamian 2002Karamian & Ranjbar 2005) and is also the largest genus in Iran, represented by ca 800 species belonging to 67 sections.
