Well, you could always sequence the species, identify plant specific

kit and then turn in some competetors, spread some rumors, then go on a
marketing blitz (with the reward money from the competetors) on how
your plants are the only "TRUE VERIFIED" legal plants. Or better yet
put out the story then charge an extra $149.99 for a cut down pregnancy
test with two red lines (sharpy $0.99) and a fancy document.

In other words, It could be done, but who really wants to pay the
millions that it cost to sequence all the plants and decide what is
"fruit of a poison tree"
However proof of guilt is on the goverment.

The best way to save the wild ones is to grow them at home (legally of
course)

I submitted my last post tongue in cheek. Need to be careful and not
make a joke that someone may take seriously and implement.

You are right though, it would probably be easy enough to insert a
NOT-virus or flag into the plant that would remain throughout its life,
and possibly be transmitted to the progeny. I would hate to compare it
to syphilis, but once positive always positive. Or maybe something
that could be tested as quickly as a home virus test strip (about $20
per test) or as you said a home pregnancy kit.
