This is only a general comment.

Good taxonomists who erect species do not depend on minor floral structures only but consider more characters and now a days based on supplementary supporting characters. Good peer reviewed Taxonomic Journals publish species only after some good exercise to avoid  such situation.

There may be cases where  papers are published without genuine study, but they usually come in journals without any reputation and in due course get assessed in authentic revision studies.  

I wish to say that the situation is not so panic.
