The justification for studying quasi-sum production functions is that these functions appear as solutions of the general bisymmetry equation and they are related to the problem of consistent aggregation (see [1]).

This review will confine the discussion to the ceramic work although Miller's obsession with cellular patterning and bisymmetry is consistent throughout all of the work on view.
A straight, thick longitudinal rib runs along the axis of bisymmetry on both faces of the fruit.
The locule is also cordate in outline, somewhat inflated, bisected by the septum and a strong vein continuous with the pedicel and style, in the plane of bisymmetry.
A median vein extends along the axis of bisymmetry and over the seed cavity.
9a, b) include presence of a stipe, bisymmetry, indehiscence, two wings, a narrow, fusiform locular area, a single seed per fruit, and no ribs over the locular area, other than the prominent midrib extending the full length of the fruit.
Locular area longitudinally fusiform, 2 mm wide, 5 mm high, smooth, bisected by a median longitudinal crease in the axis of bisymmetry.
The wide spacing of the veins, lack of fimbrial vein, and straight axial bundle in the axis of bisymmetry rule out affinities with Terminalia.
Her upright forms sometimes have quite abrupt changes of contour and many of her vessels, inspired by seed forms, are given bisymmetry by means of vertical grooves or deep dimples.
