[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).
