In this paper a key, descriptions and new results are provided for Trigonella sect. Ellipticae occuring within the area covered by the flora of Iran. Trigonella sect. Ellipticae comprises perennial herbs, becoming woody at the base, with standard as long as keel and pods glabrous or rarely covered with gray dense and appressed hairs. Trigonella lasiocarpa Ranjbar & Hajmoradi, T. binaloudensis Ranjbar & Karamian, T. stipitata Ranjbar & Joharchi and T. torbatejamensis Ranjbar are described and illustrated as new species based on habit and pollen morphology. The relationships between the new species and their closest relatives are discussed. The pollen morphology of 26 specimens belonging to 11 species was studied with light and electron microscopy and discussed in the context of existing hypotheses on the systematic relationships within T . sect. Ellipticae . In addition, T. heratensis Rech. f. and T. adscendens Aphan. & Gontsch. are reported as new records for Iran.
