 Carex filiforniis and Cladium IVIarlscus In Co. Down. 



One day last Maj', driving from Strangford to Downpatrick, I 

 observed in a reed}- lake, iiot far from the road, groves of a tall sedge- 

 like plant which, even at a distance of a quarter of a mile, I recognised 

 as Cladium Mariscus. A visit to the lake showed the plant growing 

 abundantly and luxuriantly ; and, better still, the swamp was dotted all 

 over with a sedge which, though only in flower, I felt sure was Carex 

 filifovDiis. INIy brother, E. A. Praeger, has since re-visited the spot, and 

 sent mature fruiting specimens, which show that my diagnosis was 

 correct. This lake, or swamp with pools, lies not far from the main road 

 from Strangford to Downpatrick, half a mile north-west of the hillocks 

 marked " White Hills " on the one-inch Ordnance vSurvey map; and 

 both the species named grow therein in abundance. These are two of 

 the rarest members of the North-eastern flora. Cladiian was found near 

 Cajitlewellan by Templeton, and after an interval of a century was 

 re-discovered growing sparingly there by Mr. Stewart and myself ; its 

 only other station, and the only station of C. fitiformis, was Selchin, on 

 the Antrim shore of Lough Neagh, where they grew with C. elongata, as 

 discovered by Dr. Moore some sixty years ago. Cladium had been pre- 

 viously found there by Templeton. None of them have been seen in 

 that station since, having been, no doubt, destroyed by the drainage 

 operations carried out between forty and fifty years ago. C.Jiliformis 

 was excluded from the local flora by Stewart and Corry in 1888 as doubt- 

 ful, but was re-inserted in the Supplement, published in 1895, on the 

 strength of specimens from Selchin discovered in Dr. Moore's herbarium. 

 In view of the extinction of these two plants at Lough Neagh, and the 

 paucity of Cladium in its only other local station, it is satisfactory to have 

 a new locality where both grow abundantly, and are in little danger of a 



similar mishap.

Occurrence of Callltrlche truncata, Cuss., and Leucojum 



aestlvum, L., In Ireland. 



During an afternoon ramble among the Slaney marshes, a little north 

 of Macmine Junction, Co. Wexford, on June nth, I had the good for- 

 tune to come across these two nice plants, not far from Macmine 

 Castle. The former was plentiful in a broad ditch which the railway 

 crosses, and in an adjoining pool ; the latter grew in a swamp near the 

 river, some sixtj'^ or eighty specimens being observed in flower or fruit ; 

 it looked quite as wild as I have seen it in England. These marshes 

 deserve further examination ; I only worked a small part of them.
