1 88 The Irish Naturalist. June, 



an account of which has already been published in the Irish 

 Naturalist It is confined to these tidal muds, and is particu- 

 larly luxuriant along the Robertstown Creek, which is the 

 creek referred to by Mr. More, and which has furnished many 

 of the rarer plants on our list. 



Last year, we added another rare grass to the flora of the 

 South of Ireland from this part of the barony. On Trummera 

 Big, one of the small islands off Aughinish, we found Glyceria 

 festuc(zformis> growing also on the intertidal part of the beach. 

 This discovery has also been already published in the Irish 

 Naturalist 



In the meadows bordering these creeks, the Pyramidal 

 Orchis, the Great Knapweed, the Yellow Goat's-beard, and 

 the Blue Salsify are conspicuous plants. In the drains are 

 Dropworts, the Narrow-leaved Water-Parsnip, the Bull-rush, 

 Carex riparia, &c, and the ponds are choked with Potam ogeton 

 pcctinatus, Chara hispida, and Zannichellia, &c. 



As the land rises from the shore, the creeks and hollows 

 become marshes floored with sticky marl, in which Juncus 

 maritimuSy /. obtusiflorus, Cladium Mariscus, Phragmites 

 communis, Carex acuta, and Sch&?ius nigricans are the charac- 

 teristic plants, with Bog Thistle, Arrow-grass, Pedicularis 

 palustris and Carex extensa as a thick undergrowth. In one 

 of these marshes at Barrigone we found Equisetum variegatum. 

 Further inland the land rises higher and forms the well- 

 known crags of the Mullough district, drained by a small 

 stream, known as the Ahacronane river, which, rising south 

 of the Mullough mills, flows through a fertile hollow in the 

 crag-lands to join the Shannon at Robertstown. The whole 

 vegetation of these crags is stunted and close-growing. They 

 are covered in many parts with scrub of Thorn, Holly, Sloe, 

 Cherry, Crab-apple, Spindle-tree, Guelder Rose, Dogwood and 

 Hazel, the last two growing to fair sized shrubs, in the lower 

 damper ground through which the stream flows. The Burnet 

 Rose, Viola hbta, Rubia peregrina, the Stone Bramble, the 

 Lesser Burnet, Mullein, Geraniu??i columbinum y Euphrasia 

 Salisburge?isis and Orchis py?'a?uida lis are characteristic plants 

 of the district. Of the rarer plants, the Juniper, found in 

 only one spot, the Moonwort, Spiranthes autumnalis, Musk 

 Mallow Gromwell and Columbine are the most notable. At
