). The agricultural context of the Beit-Netofa valley, and its anthropized hydrology (canal) represent thus both possibilities for management and threats if sudden changes in land use or hydrology disturb the sites. This is even more important as these populations are the only known occurrence of this species, thus they are of very high conservation value. IUCN Conservation status assessment would require more field explorations, in order to have a better information on the distribution and the demography of the species. Thus, botanists of the

Nature and Parks Authority were reported about the species, and we hope now that study of the spread of the species will allow exact assessment of the conservation status.
