1896.] COLGAN. — Flora of the Ox Motmtams, Co. Sligo. 307 



Rubus saxatllis, Linn. — Sparingly on the northern slope ofKnock- 



acree and at the head of Lugdoon. 

 Potcntllla reptans, Linn. — Roadside banks near the sea below 



Dromore West. A rare species in many parts of West Ireland. 

 Saxffragra alzoldes, Linn. — Abundant on Knockacree from about 



300 to 900 feet, but confined to the gully above Lough Acree and to 



the neighbouring rocks. First observed here by Miss Kinahan, in 



1S93. 

 Gnaphallum sylvatlcum, Linn.— Gravelly places by the shore of 



Lough Basky, and luxuriant on dry banks in the Mass Valley. 

 Hleraclum Irlcum, Fries. — Sparingly in rocky places above Lough 

 Acree, at about 450 feet. The only Hawkweed observed in the 

 district except the ubiquitous H. Pilosella. 



Vaccinlum Vltls-Idaea, Linn. — On Knockacree at 1,400 feet, and 

 abundant round Cloonacool lough to 1,350 feet. 



Salfx herbacea, Linn. — At Lugdoon, at Cloonacool lough, and on the 

 mountain east of Lough Easky, descending to 1,200 feet. Very 

 stunted where it clings to the wavy foliations of the gneiss, but well- 

 developed when growing in the grass}^ or mossy capping of the 

 rocks. 



Epipactis palustrls, Crantz. — Abundant in one spot on the northern 

 shore of Lough Talt. 



Juncus obtusif lorus, Ehrli. — In a marsh below Dromore West, and 

 sparingly near the margin of Lough Acree. Apparently a new 

 record for District IX. 



J. suplnus var. fluitans^ Lamk. — A characteristic plant of the lakes 

 in this district, occurring in Lough Acree, Lough Easky, Lough 

 Glendarragh, and Cloonacool lough, and also in many of the 

 loughauns in the central plateau. The young shoots developed by 

 this viviparous form in the deep water of these lakes are exquisite 

 examples of extreme tenuity of leaf, and exhibit perhaps the nearest 

 approach amongst the Irish phanerogams to truly capillary foliage. 

 When detached from the parent and stranded on the lake shores 

 the young plants are very puzzling, and easily mistaken for forms of 

 Scij'pus acicularis. 



Sparg^anlum alTine, Schnzl.— In Lough Ramduff near Lough Easky, 

 and again in Lough Glendarragh, where it covers a large surface and 

 flowers and fruits freely at a height of 1,332 feet- 



Osmunda reg^alls, Linn. — Appears to be very rare in the district. 

 Only one large patch observed, by a stream near Croagh, north of 

 Lough Easky. 



Botrychlum Lunaria, Sw. — In pastures near the old tower below 

 Dromore West. 



Adlantum^ CaplIIus-Vencrls, Linn. — Specimens of this species 

 gathered on limestone rocks by the river below Dromore West were 

 sent me near the end of July last, by Mr. John Quirk, who informs 

 me that it grows in this station in considerable quantity. The plant 

 was reported from this locality by Mr. R. Warren, in 1891.
