    We describe a statistical model over linguistic areas and phylogeny.
    Our model recovers known areas and identifies a plausible hierarchy
    of areal features.  The use of areas improves genetic reconstruction
    of languages both qualitatively and quantitatively according to a
    variety of metrics.  We model linguistic areas by a Pitman-Yor
    process and linguistic phylogeny by Kingman's coalescent.
