Will molecular phylogenetics help decrease nomenclatural instability?

Gene trees and species trees: Molecular systematics as one-character taxonomy.

Taxonomists and non-taxonomic botanists should also realize that another source of discordance between gene trees and species trees is transfer of mitochondria or chloroplasts across species boundaries.
