Point quadrat readings, taken to assess density of foliage in a plant, determine a contact frequency function f. A formulais given expressing the average foliage density of the plant in terms of f. This is compared with the work of Philip, who determined from f using a foliage angle density function g and an approximate Fourier analysis.
