Collecting spanish populations of the genusAegilops L.

Summary Several expeditions were made to the greater part of Peninsular Spain and the Balearic Islands, in order to collect samples from populations ofAegilops spp. The result has been the compilation of a collection reflecting both the presence and the distribution of the genus in Spain. The localisation and collection of two populations ofAe. cylindrica is particularly noteworthy.Ae. ovata is found all over the Peninsula except in the north and northwest of the country. It extends also to the Balearic Islands, which lie within the same biogeographical region.Ae. triuncialis also has a widespread distribution though smaller than that ofAe. ovata. In the Balearic Islands it is found only in Mallorca. All other species were found in more localised areas.Ae. neglecta was found in regions of W and SW Spain with the limits of its distribution bordering those ofAe. biuncialis, which is found in central Spain and in the South.
