Summary
Diploid Hordeum bulbosum L. (2n=2x=14), collected for the first time in south-west Spain, is described. One hundred and ten plants from the original seed were grown to maturity to determine the type and extent of phenotypic variation within the population. Cytological study verified that all the plants were diploids. The plants proved to be variable for traits such as growth type, tiller number, culm and spike length, flag leaf length and width and bulb characteristic and size. The variation in the diploids was found to be greater than previously reported. The plants found in elevations 150–250 m do show differently to other groups with respect to several morphological characters.
