A new way of dissemination in Anagallis arvensis L. (Primulaceae)

Jacek Drobnik, Barbara Bacler

Abstract


Anagallis arvensis L. fruits are globose pyxides. They contain a unique globose columella with 20-30 seeds on its surface. In ripe, open fruits the ball-shaped columella detaches easily and becomes a unique diaspore, which can roll on the ground. This way of dissemination has not been described so far neither in Anagallis nor in other Primulaceae.

Keywords
