Open sandy ground in a disturbed area of heathland with Comptonia peregrina (Sweet Fem) and Viola sagittata van ovata (Arrow-leaved Violet). Photo by P. M. Catling in 2004 at site 8. pronounced, but with only two anthropogenic sites, a more detailed comparison is unnecessary. The apparently longer persisting natural barrens in Nova Scotia are readily divided into two major vegeta- tion types based on either granitic or sandy substrates (personal observation). Sandy heathlands like those of the Annapolis Valley were also well developed in the interior of Yarmouth County and near Debert, Spring- hill, Parrsboro, and on coastal dunes in Guysborough and Kings counties and on Sable Island. The coastal heathlands on sand differ from the interior sites in both species composition and species abundance, and the differences suggest adaptation to different conditions. Differences also exist at the infraspecific level. For example Lechea intermedia var. intermedia occurs in interior heathlands while L. intermedia occurs on the coastal sandy heathlands. The heathlands on Sable Island appear distinct (Catling et al. 1985). The interior sandy heathlands also appear to vary re- gionally, presumably due to differences in climate. The climate in southern Yarmouth and Shelbume differs from that of the Annapolis Valley (personal observa- tion). The data suggest that the Annapolis heathlands are distinctive in their floristic composition. Acknowledgments Mark F.
