Re: BRYONET: ventral surface of leaf


Since we are on some frequently used terms, I have been putting together a
key to the bryophytes of the area where my course on tropical bryophytes
is to be taught. In keying liverworts I find preferable the terms
"antical" and "postical" to refer to the margins of leaves of the
Jungermanniales. When one uses the terms "dorsal" and "ventral" the idea
of succubous and incubous must be kept in mind before one can answer the
question of which margin is dorsal and which margin is ventral.
