Big Snip~~

Taking all the above into account the only conclusion, logically, is that if
the original poster, Judith Lea, had given the correct botanical name for
her Mare's-tail by consulting a flora; then she would not have obtained the
information she wanted.
Her mistake, compounded by ours, came to the conclusion she did want!!.
Near to a double negative!
Botanical names only have value if applied to the correct plant.
Regrets! Brian
