1897.] Cot,GA.^.— 07k the Flora of the Shores of Lough Derg. 195 



HIeracIum umbellatum, Linn.— Abundant on many of the islets 

 and promontories of the lower half of the lake as (VI.) on Young's 

 Is., Hare Is., Yellow Is., and Farrahill Point, Galway ; on theLushag 

 rocks and Long Is., Clare, and (VII) on Scilly Is. and Ryan's Point, 

 Tipperary. 



Samolus Valerandl* Linn.— Generally supposed to prefer the sea- 

 side, but more abundant round the shores of Lough Derg and its 

 islands than I have ever observed it to be by the sea. Also recorded 

 as common on Lough Ree by Messrs. Barrington and Vowell. 



Centfana Amarella, Linn.— VI. Rinmaher, Horse Islands, Bushy 

 Is., Ilaunmore, &c., Galway.— VII. Derry Is., Slevoir Point 

 Dromineer, &c. ; abundant along the lake as far as the limestone 

 extends. 



Scrophularlaaquatlca, Linn. — VI. Bonaveen Point. — VII. Gortmore 

 and Drominagh Point ; abundant in the latter stations in dry rocks 

 some feet above water mark. 



Orobanchc Hedcrae, Duby. — VI. Round the ruined church on Church 

 Island near Portumna. 



Utrlcularia neglecta, Lehni. (.?). — VI. and VIL A form with small 

 bladders which came up on the drag from deep water at Rinmaher 

 near Portumna, and at Slevoir Pt., Tipperary, Mr. A. Bennett is 

 inclined to place here, but the absence of flowers prevents a positive 

 identification. 



Origanum vulgarc, Linn. — VII. Near Dromineer and on the Corri- 

 keen islets, but rare. 



Teucrlum Scordlum, Linn. — Perhaps the most characteristic of the 

 littoral plants of Lough Derg, appearing in profusion all along the 

 shores of the lake and of its islands from Portumna south to Rinea- 

 crush, Co. Clare. The following are a few of the stations noted : — 

 On the west side— Rinmaher, Stony Is., Horse Islands, Ilaunmore, 

 Cribby Is., and Inishcaltra; on the east side— Derry Is., Slevoir Pt, 

 Gortmore, Bounla Islands and Ryan's Pt. Not seen on the lower 

 lake from Rineacrush to Killaloe. Also abundant on Lough Ree. 



Plantago marltlnria, Linn. — VI. Farrahill Point, Ilaunmore and 

 Yellow Is. The last station is 25 miles distant from the nearest sea, 

 and appears to be the most inland hitherto recorded for the species 

 in Ireland. 



Junlperus communis, Linn.— An abundant shrub or dwarf tree on 

 the islands and along the lake shores from Portumna to Mount 

 Shannon, apparently ceasing with the limestone. The following are 

 a few of the stations noted :— VI. Church Is., Rinmaher, Stony Is., 

 Yellow Is.— VII. Gortmore, Slevoir Point, and Bounla Islands. 



Elodea canadensis, Michx. — At Portumna, at Mount Shannon, and 

 flowering in bog drains at Killaloe, but rare all along the lake and 

 said by the boatmen to have much decreased of late years. In Lough 

 Gill, Sligo, and in Lough Erne and Lough Ree, a marked decrease 

 of this aggressive weed has also been observed,
