Mr. Hieber, Thank you replying,
I would think that an agreed upon definition of terrestrial is that once
submerged it begins to decay?
Prudence would direct one's quest to asking a Botanist as to the definition,
I will openly admit that I am not one .
The Botanist would probably say that it's some structure or function of the
plant, I.E. being able to withstand being submerged, something like the
fundamental difference between Salt Water Fish and Fresh water fish in how
they process salt from the water giving them the ability to drink salt water
and still be getting absorbable fresh water, I believe it's called
osmosis???????
I realize that this is a simplistic approuch to a complicated answer.
Well thanks again, Mark
