on the map proved to be the top of a whale-backed cultivated 

 ridge. Half a mile west of this, just south of Rockhill, I 

 found limestone ground answering to the description, even to 

 the gable- ends of a ruined cottage which Mr. Hart told me 

 would be a sign that I was "hot." But no trace of the Rock- 

 rose could be seen ; and until the discoverer vouchsafes 

 further information as to the exact circumstances under 

 which the plant occurs — or occurred — its range, and quantity, 

 I for one cannot follow Mr. Hart in claiming for the species a 

 place in our indigenous list, and must perforce follow the 

 lead of " Cybele." We want to know more about it. In the 

 evening, however, I was recompensed for my journey of 150 

 miles and fruitless day by the addition of an interesting 

 plant to the flora of Donegal and of. Ulster — namely Rhyn- 

 chospora fusca, which grew on the bogs south-west of Belleek 

 with Drosera intermedia, Carex limosa, &c. The latter two 

 crossed the border into Fermanagh, where they were very 

 welcome, each having only one station in District X., but 

 the Beak-rush I saw on the Donegal side alone. Late the 

 same evening I rode on to the little inn at Garrison, on Lough 

 Melvin. The edge of the lake here was fringed with patches 

 of the rare Potamogeton filiformis in beautiful fruit. I have 

 already recorded it from the Leitrim side of Lough Melvin. 



In the Irish Naturalist, v., 188 (1896) Mr. W. MacMillan, 

 the finder of several rare plants, recorded the Globe-flower, 

 Trollius europczus, as growing " in an unquestionably wild state 

 on the shores of one of the larger Fermanagh lakes." There 

 was no inherent improbability in his statement, as the plant 

 grows wild in the adjoining count} 7 of Donegal. Nevertheless 

 the record is not even mentioned in " Cybele." So I was up 

 betimes next day, and rowed from Garrison through the 

 morning mists towards the island on Lough Melvin to which 

 Mr. MacMillan had kindly directed me. There are three 

 islets at the north-east end of the lake. The one which is 

 named on the one-inch map Bilberry Island is locally called 

 Heather} 7 Island, on account of the long heather with which 

 it is covered. Close outside it is the low Sally Island. More 

 to the west is Gorminish (one-inch map) or Bilberry Island 

 according to local phraseology. For this place I steered, and 

 as the boat's keel grated on the pebbles, I saw a leaf of 

 Trollius floating in the water. Landing, the plant was found
