I agree with Joseph comment, to tell  that "key of 10 close related species
is reqired" make situation worse than before, but to tell that in the new
descriptions has to be : What Has It Common With Related Species! In other
words,  the (presumable) synapomorphs has to be indicated, ...this is
achievement....

>Very good point. If I say "Similar to Planta hypothetica
>but with purple flowers" I am implying but not stating
>that they have the same leaf shape, stem pubescence, etc.
>But the two species might differ in other ways beyond
>the flower color. Indeed, if there were only one character
>separating the two, I would desire more evidence that
>the new taxon was worthy of recognition as distinct.
>    A dichotomous key would not necessarily address this
>point. Most such keys concentrate on differences between taxa
>one character at a time. The are better ways in which to
>discuss similarities and differences between two
>closely related species.
>   My basic point is that there are thousands of different
>circumstances, each with its own solution. Sometimes the

>1. Planta novissima has purple flowers.

>2. Planta novissima has purple flowers whereas all the

>In my humble opinion, #2 has successfully distinguished

Keep care and be of good cheer.
