The fruit is a small, ellipsoid drupe, which is bluish-black when ripe.
Of the two eggs, one is of an ovoid form, having much the shape of a hen's egg; and the other is an ellipsoid.
Its form is that of an ellipsoid, with a major axis 26 millimetres in length, while the minor axis measures 11 millimetres.
The form of the latter is at first globular, then ellipsoid, and more or less curved.
Sporangia globose or ovoid to ellipsoid or oblong, erect or sometimes inclined or even nodding.
ellipsoid, a surface bearing the same sort of relation to a spherical surface as an ellipse bears to a circle.
A surface expressing the optical relations of such crystals is thus an ellipsoid of revolution about the optic axis.
Similarly, the dielectric constants of a non-conducting crystal may be expressed by a sphere, spheroid or ellipsoid.
Therefore the surface is an ellipsoid of revolution having A and B as foci.
We may, however, assume the ellipsoid with three unequal axes to be an interpolation form.
