Until reading your third question, I thought it clear that this was
certainly a recombination statement, standards having been laxer in 1940
than in 1997. This would make it Trillium grandiflorum var. orbiculare
(Farwell) Louis-Marie. However, if it was listed as a synonym and not
accepted by Louis-Marie, the variety is not a validly published name. If
you list it at all in your monograph, it should have "nom.  inval., pro
syn." after it.

No. Names published before 1958 are valid even if no type has been
published at all. You can correct problems in typification as you see fit.

>    Is platipetala for platypetala considered an orthographic variant?
