Bidirectional reflection and transmission distribution functions are measured for healthy green soybean and corn leaves in vivo, for nineteen narrow wavelength bands from 375 nm to 1000 nm. Off-normal incidence reflection distribution functions show considerable specular contributions at wavelengths of strong absorption, while transmission distribution functions show a near-lambertian shape for all wavelengths employed. An empirical m-layer leaf model affords a reasonable qualitative understanding of these scattering distributions.
