  A parametrization of (super) moduli space near the corners corresponding to
bosonic or Neveu-Schwarz open string degenerations is introduced for
worldsheets of arbitrary topology. With this parametrization, Feynman graph
polynomials arise as the $\alpha ' \to 0$ limit of objects on moduli space.
Furthermore, the integration measures of string theory take on a very simple
and elegant form.
