From: Rheophytic Osmunda lancea (Osmundaceae) exhibits large flexibility in the petiole
Sclerenchyma data, (a) safranin-stained cortex sclerenchyma in lateral view, bar = 100 µm; (b) relationship of transverse area of petiole and sclerenchyma length; circles indicate O. lancea, squares indicate O. japonica; (c) comparison of sclerenchyma length. Box whisker plots marked with different letters differ significantly according to t-test (p < 0.05). Crosses indicate position of the mean.
