I see your point. Going  by your suggestions, can we have

organismal physiological process GO:0050874
-[i]-vivipary
---[i]-vivipary sensu metazoa
-----[i]-pregnancy GO:0007565
---[i]-vivipary sensu magnoliophyta
-[i]-seed germination GO:0009845
---[i]-vivipary sensu magnoliophyta

It looks kind of odd but it may work.
In my previous suggestion all the terms AKA "vivipary"  can
be replaced with 'vivipary sensu magnoliophyta"

For Jen:
I suggest excluding the bryophyllum type of vivipary from
this . It should be considerd as a vegetative propagation
(is_a asexual reproduction).

Hi,

I know this is almost exactly the same comment I made on this
discussion earlier, but we cannot use plain 'vivipary' in a way that 
restricts
it plants. The word has a broader meaning and is applied to animals as
well as plants. Here's the dictionary.com definition for 'viviparous':

vi-vip-a-rous
adj.

Zoology. Giving birth to living offspring that develop within
the mother's body. Most mammals and some other animals are
viviparous.

Botany.  Germinating or producing seeds that germinate before
becoming detached from the parent plant, as in the mangrove.
Producing bulbils or new plants rather than seed, as in the tiger
lily.

Thanks,
