General/Distribution: A genus of about 20-25 species in Europe and western Asia; 3 species occur in Pakistan.
Comment/Acknowledgements: The genus is closely related to and sometimes united with Triticum, but although hybrids occur the two genera are sufficiently distinct morphologically to warrant maintaining them both.

Aegilops kotschyi Boiss. has been reported from Pakistan, but according to Stewart (Ann. Cat. Vasc. Pl. W. Pak. 171. 1972) the material in question was probably collected in Afghanistan. No material definitely from our area has come to light. It differs from Aegilops triuncialis by its glumes having equally broad, evenly spaced nerves.
