Barrtngton and Vowell — Flora of Shores of Lough Ree. 699 



resting from its also occurring on similar small islands in the middle 

 of Lough Erne. Calamintha acinos, hitherto only found in Dublin and 

 "Wicklow. Teucrium scordium occurs in abundance. There is an old re- 

 cord about it, fide I. B. (Isaac Butler) Annot. in Threlkeld. Rumex 

 hydrolapathum was noticed on both the Leinster and Connaught shores, 

 and Potamogeton rufescens near Ballykeeran. A curious Potamogeton 

 growing in the Inny was submitted to Mr. Bennett of Croydon, an. 

 authority on this difficult and very variable genus, and he has referred 

 it to P. fluitans, Eoth (?). Ripe fruit, however, must be procured 

 before this species can be added to the Irish flora with certainty. P. 

 zizii, a species recently added to the Irish list, was abundant. Pota- 

 mogeton fili/ormzs, which belongs to Watson's Scottish type, and whose 

 range has been lately extended in Ireland, was frequent. Habenaria 

 cMorantha could only be found in one spot, whereas S. lifolia, which 

 is far less common in Ireland, was plentiful. Cephalanthera ensifolia, 

 a very rare orchid, grew on the shore of Hare Island in tolerable 

 plenty. Cladium mariscus was frequent, and Scirpus acicularis was 

 seen on the west side. Carex teretiuscula, a local plant, grew in. 

 many places. On Temple Island a remarkable Carex was noticed; 

 but it may be only a form of C. stricta. Chara tomentosa^ so very 

 rare in England, but which the late Dr. Moore found in Lough Derg 

 and in Belvidere Lake, grew plentifully in a few places. A Chara 

 without fruit may prove to be C. strigosa, and if so, a species new to 

 Ireland. 



Plants certainly introduced are marked (*•) ; those probably intro- 

 duced (I) ; and species possibly introduced (|). 



"We are indebted to Mr. Arthur Bennett for his assistance in 

 examining the Potamogetons, and all the Characese have been kindly 

 named by Mr. Groves. 



N.B. — Those species already recorded in the " Cybele Hibernica," 

 or in its Supplement, published in 1872, from all the twelve botanical 

 districts into which Ireland has been subdivided in that standard 

 work, are omitted. These common species number 270, and all were 

 obtained but the 15 enumerated already. The total number observed 

 was 481.
