near Athlone ; Cauaclis nodosa, among the ruins of Castle 

 Sampson ; and 1 Mentha piperata on the site of Corkip Lough. 

 The railway tracks some miles west of Athlone yielded 

 Diplotaxis 7nuralis and Armaria tenuifolia, and, of course, 

 abundance of Lt7iaria viscida ; close to Athlone Matricaria 

 discoidea began, and almost monopolised the space. The same 

 group of plants, minus Diplotaxis, grow on the railway east of 

 Athlone (Co. Westmeath). Taking train next morning to 

 Mullingar, the first plant seen was Matricaria discoidea again, 

 swarming about the railwa}' and over the adjoining roadway 

 to the canal banks. Six miles of canal to the west of 

 Mullingar yielded little, and I turned northward to lyough 

 Owel, and thence to lyough Iron. Lough Iron does not appear 

 to have been explored by Mr. Levinge, and its southern end 

 yielded a good marsh flora, including Lathynis palustris^ 

 Cicuta virosa, Galiiim uligijiosiun, &c. The River Inny, 

 between I,. Iron and Ballinalack, yielded some peculiar plants, 

 including a large pondweed still unnamed, and a sedge 

 which most resembles C aquatilis. I now struck across 

 country towards Lough Deravaragh. For some years past 1 

 have noticed when passing in the train a large patch of what 

 I felt certain was Typha angustifolia growing in the Inny below 

 the railway bridge. An opportunity was now afforded of con- 

 firming my diagnosis, and I was much pleased to find that my 

 surmise was correct. Excepting the recently discovered 

 station in Kilkenny (/.A^., viii., 11) this plant was known to 

 grow only in Ulster. The new^ station furnishes a connecting 

 link between the northern and southern localities. It was 

 now late, and I caught the train for Dublin at Inny Junction. 

 . My next trip was to Co. Waterford. July 7 found me 

 established at Dungarvan, which may be the dirtiest town in 

 Ireland, as stated in one of Mr. Hart's papers, but possesses 

 one of the cleanest hotels. The first day was devoted to 

 listing plants in the near vicinity. The following morning I 

 turned my steps eastward along the coast. About Abbeyside, 

 Ru?nex pulcher grows in some quantity. Excepting its casual 

 occurrences about Dublin, this plant was previousl}' 

 known only from Co. Cork. It w^as accompanied here by 

 Raphanus maritijuus. Clonea marsh, which has been described 

 by Mr. Hart in his " Flora of the Wexford and Waterford
