[Taxacom] Herbarium sequence revisited

I'm not a botanist, but seems to me the best compromise would be
phylogenetic down to family. Then perhaps arrange the genera and species
alphabetically within each family.
And with the collection arranged in four vaults, one vault could be
primarily for the monocots (Class Liliopsida), which comprise about 25% of
the angiosperm diversity. As for the dicots, the paleodicots would
obviously come first, but arranging the higher dicots in a linear fashion
would be a judgment call (since their phylogeny is so "bushy" and somewhat
less certain relatively speaking).
