Comments Stomata are usually spaced several mesophyll cells apart and as Parkhurst (1994) pointed out, the reported range of stomatal densities is approximately 10–2000 stomata mm-2 (values from Willmer & Fricker 1996), which equates to interpore spacings ranging from 24–340 um (assuming uniform triangular grid spacing, which is a simplification).
