BRYONET: (no subject)

Subject: RE: BRYONET: Ventral surface of a leaf [SEC=Unclassified]

Well, I am moved to reiterate my original point (along with David
Wagner) - ad = adjacent to and thus it matters not whether the plant is
erect, horizontal, or hangs down vertically (or obliquely). There is
only ever one side adjacent to the axis (i.e., adaxial). I also agree
that the situation is different in liverworts and mosses.
And, I hasten to add, I have become utterly confused by the various
definitions and reasons given for upper and lower, dorsal and ventral,
adaxial and abaxial, antical and postical, etc.
