A couple mystery plants today on the bike ride

(which apparently is not multiflora rose because it doesn't
look like this http://home.att.net/~rhhardin5/w60.jpg )

Actually, because of the change in heterozygosity by selfing, I consider
it as very different from cloning. Heterozygosity decreases by 50% with
each self pollination.  If we buy the evolutionary argument that
heterozygosity is generally good within a population, then when

Can anyone identify them?
I need their names for proper keywording, as I shoot them and uploaded their

Can anyone recommend a good insect newsgroup? If not, have you got a
great website to recommend?
I've checked the listings and my server [Giganews] does not list one.
Many thanks for taking the time to respond!  ;-)

There must be a lower limit as to the size of a seed, for which it is
impossible to grow a plant therefrom. A strawberry seed is very small
but probably not the smallest in existence.
Elm seeds are small in relation to becoming a woody plant of a tree.

monique & everybody,
have you preserved flowers using ethanol?
could you direct me to a procedure in the lit or tell me how you do it?
thanks
