Morphometric data on Apobryophyllum schmidingeri. Data based on mounted, protargol-impregnated (Foissner 1991, protocol A), and randomly selected specimens from a non-flooded Petri dish culture. Measurements in μm. CV – coefficient of variation in %, M – median, Max – maximum, Min – minimum, n – number of individuals investigated, SD – standard deviation, SE – standard error of arithmetic mean, $\stackrel{‒}{\mathrm{x}}$ – arithmetic mean.

^aRow 3 excluded. Rough values because the end of the brush is difficult to recognize due to the occurrence of monokinetids.
