These are above the usual vertical limits of several of the 

 species. The adders-tongue is remarkably abundant on the 

 western slopes of the Devil's Bit. Nothing else of interest was 

 noticed along these hills to the northern extremity of the chain. 

 During the detour already mentioned, along a stream which 

 proved to be a tributary of the Brosna, flowing west to the Shannon, 

 I met with Geum rivale, Alchemilla vulgaris, Sambucus ebuhis, Cre- 

 pis paludosa, Antennaria dioica, Mumulus lupulus, Carex remota, 

 C. syhatica, Equisetum maximum, and E. sylvaticum. 



The following day, May 30, having driven to Borrisnoe, 

 as far as the roads would permit, we crossed country and fell in 

 with the stream on the eastern slope of Benduff. On the upland 

 pasture ground I noticed Carduus pratensis, Rubus idceus, Lathyrns 

 macrorrhizus, Habenaria viridis, and Polystichum angulare. The 

 river flows between high and wide clayey banks at its source, and 

 soon settles down into a winding, rocky, sandstone bed, amongst 

 copses and bluffs of oak, sallow, mountain ash, blackthorn, and 

 other shrubby vegetation. For a couple of miles here the stream 

 is rapid and very pretty, and hedges are numerous, Carex piluli- 

 fera, C. Mrta, C. actita, and C. remota. with the commoner sorts 

 being noted. Valerian and the graceful water avens {Geum rivale) 

 also decorate the banks. In this part of its course the river is 

 much frequented by water ouzels.. Young and old were continually 

 flitting across our path. Near Skehanagh bridge I gathered 

 Lycopiis europceus, Juncus glaucus, Carex ovalis, and C. jjaniciilata. 

 At Killough bridge Stimulus lupulus has established itself, and 

 here also Equisetum maximum was observed. Soon after this bridge 

 the river Suir, which has hitherto been flowing eastward, turns 

 south, and runs a straight and apparently artificial course between 

 hedgerows through rich flat lowlands in a slow and uninteresting 

 manner. Along here Barbarea vulgaris is very frequent, with com- 

 moner grasses, water mint, the larger forget-me-not, and yellow 

 iris. Between Knockane bridge and the railway, where the Suir 

 comes inside District 2, Epilobium hirsutum, Myrio^ohyllum alterni- 

 florum, Potamogeton natans, P. crispus, Carex paniculata, G. vesicaria, 

 C riparia, and Juncus glaucus were met with. 



Several of the species enumerated up to this are additions to 

 the flora of District 7. At this point the Great Southern and 

 Western Eailway is the boundary, and the remainder of my explo-
