– Only two plants of the species were found in the surveyed field, which was traditionally cultivated with barley and oats. The weed vegetation was very species-rich, the most abundant wild plants being Bifora testiculata (L.) Spreng., Dasypyrum villosum (L.) P. Candargy, Neslia apiculata C. A. Mey. , Papaver rhoeas L., Ranunculus arvensis L., Rhagadiolus stellatus (L.) Gaertn., Valerianella echinata (L.) DC., Veronica glauca subsp. peloponnesiaca (Boiss. & Orph.) Maire & Petitm. and Vicia striata M. Bieb. , among many others. Euphorbia serrata is widely distributed in the W and C Mediterranean, where it occurs in species-rich cereal fields on base-rich soils (see, e.g., Nezadal 1989). The occurrence in S Greece should be considered native, because there was no incidence of recent casual introductions in the field and its surroundings, and the seeds of the cereals are domestic. E.
