Taxon Sampling in Morphological Studies

[Thomas Schlemmermeyer]

Even if not for the sake of itself, but in order to check origin of certain
traits, it might be appropriate to make a phylogenetic study of a group.
Time and money is short.

Are there any good references dealing with extremely restrictive taxon
sampling (using only very few representants of each higher group), or
is it not reasonable at all to use only very few representants?
