Scanning electron microscopic investigation of seed and capsule morphology of Arenaria serpyllifolia L. and A. leptoclados Guss. In the Caryophyllaceae have been studied. Seed size in both species show consistency, but testa ornamentation (midzone) vary in shape even in the seeds from one capsule of A. serpyfolia, while in A. leptoclados midzone cells are narrowly elongate in different populations and environments. The ripe capsule teeth ornamentation has a diagnostic character to separate A. serpyllifolia and A. leptoclados.
