SINCE thelpubualtion by Lloyd Praeger of “Irish Topographical Bcwany” in 1901, there have been seven stokplemlntary papers which have kept our kitosvrledge of the distribution of higher plants in IreUAd up to date; the eighth of these (Proc. Roy. Irish Acad., 51 B, (3), 27; 1946) is, as Dr. Praeger says, probably the last which will be published under his own name. Nevertheless, the number of records bearing a sign indicating that the author himself had seen either a plant in its locality or a specimen from there, is a remarkable tribute to the energy and capability of a botanist who has passed his eightieth year. The present paper contains first records for the forty vice-counties together with extensions and diminutions in the areas of interesting species. Unlike earlier lists, ‘introduced’ species are included. Of especial interest are the remarks concerning the North American Myriophyllum alterni-florum var. americanum and the South American Margyricarpus setosus, while the known ranges of such species as Erica vagans, Sisyrinchium angusti-folium, Naias flexilis, Eriocaulon septangulare and several others show interesting extensions. The difficult species of Allium are elucidated, and the nomenclature of those species of Hieracium and Euphrasia which occur in Ireland are revised according to the schemes of Pugsley. The paper is concerned, too, with suggestions as to areas in which certain species and hybrids should be sought, indicating that the author, although a veteran, is still alive to future possibilities. This is shown, too, by his continued emphasis on the necessity for a biological survey by geologists, botanists and zoologists of the extremely interesting Lough Neagh, where he is convinced that such a team would reap a rich harvest.
