*Lactuca muralis, Fresen. — Several plants on an old garden wall by 

 the shore below Raheny, 1892-1902, apparently a casual introduction 

 and increasing. 



HiERACiUM MACUivOSUM, Dahlst. ? - A Hawkweed of the H. murotum 

 section, obviously new to the County Dublin and in many points 

 resembling Dahlstedt's plant, turned up quite unexpectedly on a 

 railway embankment and adjoining spoil mounds near Liffey 

 Junction on the 27th May last, while the writer of these notes and 

 his friend, Mr. F. C. Crawford, of Edinburgh, were botanising along 

 the Royal Canal. Several hundreds of plants were observed in 

 various stages of development, from seedlings up to fully flowering 

 examples, the leaves in all cases been conspicuously marked with 

 dark brown blotches. Specimens have been submitted to Rev. E. 

 S. Marshall and Rev. W. R. lyinton. So far neither authority is 

 satisfied to adopt my conjectural naming of the plant as Dahlstedt's 

 H, jnaculosum, though Mr. lyinton thinks it may perhaps be placed 

 under it as a form. 



Wahlenberg'ia hederacea, Reichb. — Grassy places near the summit 

 of Feather Bed road at a height of 1,600 feet, 1902. An interesting 

 new station, where the plant attains at once its northern limit and 

 its highest vertical range in Ireland. Said to have been found at 

 Killiney, a not unlikely place, where, however, I have not so far 

 succeeded in discovering it. Further information as to its occur- 

 rence in this station would be most welcome. 



*CampanuIarapuncuIoides, I,. — Abundant over a considerable area 

 in a sandy potato field and on adjoining banks west of Rogerstowu 

 coastguard station, 1900-03; pasture above the sea at Vico, Killiney 

 Bay, in considerable quantity, spreading over a space of 30 paces by 

 15 paces, 1899-1902 ; well established on the permanent way at 

 Kingstown terminus, 1899-1903. This plant seems fully entitled to 

 a place in the Dublin flora. 



Vaccinium Vitfs-Idaea, L.— Sparingly on the northern slope of 

 Seecawn Mountain near the summit, 1900— the second Co. Dublin 

 station, the plant being previously known only on Kippure. 



V. Oxycoccus, Roth.— In a boggy hollow on Glendhu Mountain at 

 1,900 feet, 1901 — the highest station so far recorded for this species 

 in Ireland, and the only definite station on record for Co. Dublin. In 

 the British Assoc. Guide, 1878, the plant is entered for Dublin and 

 Wicklow as "Rare on the mountains," but without any precise 

 locality. 



Andromeda Polifolia, L.— Frequent in a wet level bog on Prmce 

 William s Seat above Glencullen quarries, 1901. 



Erica cinerea, L., forma.— h curious form of this was gathered at 

 Howth in August, 1502, growing in association with the type and 

 apparently standing to it in much the same relation as the var. 

 Stiiarti Macf., stands to Erica Mackaii. In this Howth form the 

 styles and anthers are extruded from the corolla in varying degrees, 

 and on examination of the flowers in which this character is most
