The locular area is broadly elliptical and extends nearly the full length of the fruit from base to apex.
The elliptical locular area, covered with reticulate venation, contains several elliptical seeds.
The locular area is long-ovoid, with fine longitudinal veins on surface.
The locular area is ovate, with fine, irregular widely spaced longitudinal striations.
Some younger reports of this family from the Tertiary of western North America (Terminalia oregona (Sanborn) Meyer and Manchester 1997), are no longer considered convincing, because they show numerous longitudinal veins over the locular area that are not seen in any of the extant genera of Combretaceae.
The elliptical locular area has a median rib and a reticulum of isodiametric polygonal areoles.
triquetra is ovate to elliptical, inflated in the locular area, but the distal part of each carpel drawn into a membranous or chartaceous wing with radiating irregular reticulate venation and a thin fimbrial vein.
Venation consists of a straight axial bundle composed of three strong veins that extend from the locular area directly into each of the three styles, and a system of major lateral veins radiating from the midline of the fruit, these veins irregularly sinuous, running directly to the margin and contributing to the fimbrial vein, or dichotomizing once or twice, sometimes forming a loop near the margin.
The fusiform locular area has reticulate venation with more or less equidimensional areoles, but this reticulum connects with the wing venation pattern which is simple, subparallel, composed of fine veins radiating from the central area out to the margins with occasional dichotomies and anatomoses, and craspedodromous to a fimbrial vein (Fig.
The locular area is fusiform with a smooth (not longitudinally ribbed) surface.
The fruits have four wings, but two of them dominate, forming the elliptical outline of the fruit, while the other two are small (1/3 as large as the other two) forming a smaller ellipse centered over the locular area.
Venation is reticulate over the central, fusiform locular areas, but fans outward into the wings in a simple subparallel pattern, with straight to sinuous veins extending to the margin or near to the margin, either forming a loop within the margin, or abutting to the fimbrial vein, with rare freely ending veinlets.
