P. nitens, Web., var. P. intermedins, Tis. (?). In a still part of the 

 Erne river, a little below Cliff, by the right bank. Mr. Bennett 

 writes: — "A form closely approaching Swedish species, named 

 by Dr. Tiselins P. intermedins, Tis. (ad nitens). There being no 

 fruit, I cannot confidently say whether heterophyllus {forma) (?), 

 or nitens {forma) (?)." P. nitens, Web., to which we may, I 

 think, safely refer the Erne plant, is an addition to the Elora of 

 Donegal. 



P. gramineus, Linn. {P. ohtusifolius, Mert. and Koch.) In a deep 

 dyke at the narrow end of St. Catherine's Lake, south of Killy- 

 begs. It is abundant here, but could hardly be reached except 

 during a dry season. This species is recorded in the Cylele 

 Hibernica — "'Lakes in Eanet, Donegal." There is no lake in 

 Fanet I have not frequently examined, and I have never been 

 able to find this conspicuous species till now. It must be very 

 local, indeed, in Ireland. Determined by Mr A. Bennett. 



P. crispus, Linn. Kiltooris Lake, near Ardara. — A. B., — a young 

 state, not easily recognizable ; in the Erne river. 



Cladium mariscus, E. Brown. In lakes, near Cliff, Belleek ; Sheskin- 

 more, and other lakes, amongst the sand-hills north-west of 

 Ardara. 



Scirpus pauciforus, Lightf . Damp places in sand-hills north-west 

 of Ardara; by a small pond on the limestone opposite Bally- 

 shannon, south side of river ; left bank of Erne, a little above 

 Ballyshannon. 



S. taierncemontani, Gm. Kiltooris Lake, near Ardara. 



S. sylvaticus, Linn. Termon river, above Pettigo, sparingly, near 

 the town ; abundant near the source of the stream at the edge 

 of the county. The only locality in Donegal except that of the 

 Einn, given in the Cylele, which I, however, failed to verify. 



Blysmus riifus, Panz. Kiltooris Lake, Boylagh promontory, near 

 Ardara. 



Eriophorum latifolium, Hoppe. Plentiful in low, rushy, coarse pas- 

 ture near the sea by Lough Sheskinmore, north-west of Ardara. 

 A very rare species in Ireland, and additional to Donegal Elora, 

 Mr. More and Mr. Bennett agree in this decision, but the speci- 

 mens were rather far advanced. I have gathered the plant by 

 the Suir, in Tipperary, and recognized it at once. 



Carex curta. Good. Brockagh Lake, near Killybegs. Occurring in 

 one isolated patch. Mr. A. G. More has recorded this rare sedge 

 "in a wet bog near Killybegs." Possibly the same locality. I 

 have not met it elsewhere. 



C. rigida, Good. Alt Mountain, near Ardara ; Slieve-a-Tooey ; 

 Aghla, above Lough Einn.
