I was speaking of genera within one family, Sarraceniaceae, which are all
related. Sorry if I didn't make this clear. I didn't mean a central
distribution point for all cps, but for the Sarraceniaceious genera.
(or maybe two "distribution points" as they didn't necessarily all
diverge at the same time).
