Usage notes

• In botanical usage, elliptic(al) refers only to the general shape of the object (usually a leaf), independently of its apex or margin (and sometimes the base), so that an "elliptic leaf" may very well be pointed at both ends. A three-dimensional elliptical object is ellipsoid, while an object that is not a perfectly stretched circle is ovoid or obovoid.
