Two new records of Phelipanche, Phelipanche hypertomentosa (M.J.Y. Foley) M.J.Y. Foley and Phelipanche orientalis (Beck) Sojak were added to the Flora of Iraq for the first time.P. hypertomentosa was collected near the Iraqi Kuwait-Saudi Arabia border, on Jarishan-Khadher al-Mai road, and P. orientalis was collected from Kurdistan North Iraq. Their distribution, habitat and hosts were reported. Comparison and relationships between the recorded species and other closely related species were discussed.

In this study two genera Spirodela Schleiden, and Landoltia Les & Crawford were recorded for the first time for flora of Iraq. Each genus represented by one species, these species is Spirodela polyrhiza (L.) Schleiden and Landoltia punctata (G. Meyer) Les & Crawford. In addition one more species of the genus Lemna (L. minuta) was added to the flora of Iraq for the first time too. Brief descriptions with main distinguishing characters for the three new recorded species were provided. Habitat and geographical distribution were mentioned .Floral and fruit characters for Lemnaceae species from Iraqi material were tabulated and illustrated for the first time. A key to all species of Lemnaceae in Iraq was provided.
