Sporangium Exposure and Spore Release in the Peruvian Maidenhair Fern (Adiantum peruvianum, Pteridaceae)
Fig 5
Loss of mass during the movement of a detached false indusium.
The movement of the false indusium could not be quantified and is, therefore, qualitatively depicted by presenting single frames in 40 min time steps (the respective S3 Video is recorded with a speed of 1 frame per 5 minutes). The motion is continuous and accompanied by an asymptotic mass loss of up to ~42%.
