| Abstract: | The surface features of the seed of the parasitic floweringplant Striga hermonthica were examined with the scanning electronmicroscope. The details of ornamentation were constant on seedsfrom one plant but varied within and between populations andare probably due to out-breeding. The variation was not relatedto geographical origin or to host-preference. Testa patternssimilar to those reported for other Striga species were foundin the samples.
