Valve symmetry within each genus is indicated: symmetrical = symmetrical about
apical and transapical axes; dorsiventral = symmetrical about transapical axis;
heteropolar = symmetrical about apical axis Notes: 1 Valves are also genuflexed.

Homology: The Hierarchial Basis of Comparative Biology
For example, if the symmetry changes from radial to dorsiventral. problems arise.
Classically, it would still be claimed that a radial shoot changed to a dorsiventral "
shoot." A dorsiventral "shoot." however, no longer totally corresponds to the ...

The other is that the reorganization of polarity is specifically linked to and

known as isobilateral and is characteristic of monocotyledons. The vascular
