When this clear and present evidence is presented to taxonomic authorities, they will amend their databases accordingly. What has kept Gentry from communicating his findings to the taxonomists? How recent is the recently published literature? The latest taxonomic scrutiny of the Agave genus is dated September 2014. There are experts in every field who disagree with established systems of classification. How can we judge their relevance? I appreciate these discussions, and they really should be added to the appropriate species entries as comments, but I think it's important for our database to be governed by a uniform set of taxonomic rules, not a different set for each genus.
