%X This paper examines the photosynthetic response of single attached leaves (of four different species) to an increasing angle of incidence (8) of incoming radiation. The intensity of light falling upon a leaf can be deduced from geometrical optics to be proportional to cos 8. The results reported here suggest that the photosynthetic. activity of leaves exposed to a limiting light intensity follows a similar relationship. Explanations of this empirically determined relationship are discussed.
