What a silly thing to say in a public forum.
Do you ever stop to think before you hit the send key?
You're as silly as an Anseranas semipalmata.

Actually it does not require thinking to repeat an established truth.
Vernacular names are only useful in a limited social context.
If social context is not specified it is a guessing game what the vernacular
name applies to. IIRC it is not that hard to find vernacular names that
refer to as many as a hundred species. Vernacular names often are worse than
useless because people assume that they adequately name a plant when they
give a vernacular name. Old stuff, especially in a public forum.
