"Transparent Helena, Nature shows her art."
The transposition 'her shows' of the folio is merely one of those of which we have so many examples in these plays. The usual reading is that of the 2nd folio, 'here shows.'

It would seem better to read 'not ripe'; or 'ripe' may be a verb.
Act III.
Sc. 1.
"If I were so, fair Thisby, I were only thine."
