208 The Flora of Ireland. 



Larne, Carnlough, Cushendall, and Toome Bridge ; all the 

 localities in Antrim. 



Lavatera arbor ea occurs in many stations on the east coast 

 of Antrim, always by houses, and has no claim, in District 12, 

 to rank as a native. 



Geranium pratense grows at Dunluce and Port Ballintrae, 

 and not G. sylvaticum, as suspected in the Cybele. 



Myriophyllum dlterniflorum is common in Antrim. M. 

 spicatum is rare. 



Arctium interviedium is a common plant on the Antrim 

 coast ; A. minus was not seen. 



Orobanche rubra is not confined to the basalt in District 12. 

 It was gathered on White Limestone, at Ballintoy, and at Bally - 

 voy, near Ballycastle. 



Helminthia echioides grows wild on Island Magee, Dis- 

 trict 12. 



Calamagrostis striata, confined to the shores of, and islands 

 of Lough Neagh, was discovered in profusion on the shores of 

 Lough Beg., county Derry. 



There is no value in retaining localities whence species 

 have long since been eradicated, and where there is no possi- 

 bility of their reappearance ; preserve the record, but do not 

 confuse collectors by the insertion of erroneous references. In 

 the volume before us are too many examples of this kind, 

 which, we presume, have been inserted through ignorance of 

 the present unfitness of the locality for the growth of the 

 species. Typha angustifolia does not now grow near Belfast. 

 The ditch near the Belfast Linen Hall, where, in the last cen- 

 tury, Lemna gibba grew, has many years been filled up. 



In several instances the locality of a species appears under 

 two or three names. This is decidedly objectionable, for not 

 only is the bulk of the volume increased, but an erroneous 

 impression as to the frequency of its occurrence is produced. 

 Thus, the locality for Rosa Hibernica — " hedges on the shore 

 near Holywood, Belfast Harbour'''' — postively includes " hedge- 

 rows half way between Holywood and Belfast" of one, and 

 " Hedge, Tillysburir" of another author. 



Despite the aid rendered by two eminent London botanists 

 in the revision of the proof-sheets, there are very numerous 

 errors, both of omission and commission, in the volume.
