Abstract: New records of thousand-seed weight are reported for 227 members of the Hungarian dicotyledonous flora (including some introduced or naturalised species). Seed samples were harvested from natural populations, kept dry until the end of the vegetation period, then the seed weights were determined. One to three hundred-seed lots were used for measurements with accuracy of 0.1 mg (up to 30 g) and 0.1 g (above 30 g). Thirty-seven of the new records belong to protected species of the Hungarian flora. When the average seed weights of three distinct species groups (1: annuals and biennials, 2: non-woody perennials and 3: woody perennials) were compared, the group of woody plants showed significantly heavier seeds than the other two groups (Kruskal-Wallis test, P !!!!!!!kisebb mint!!!!!!!!!! 0.001). However, seed weights of groups 1 and 2 were statistically identical
