of plants in general and their classification, Miss Martin gave a graphic 

 description of the flora to be seen in the woods and marshes in the 

 neighbourhood. The President spoke on the use of the microscope in 

 examining the different forms of minute fungi. Mr. O'SuUivan gave 

 some interesting information as to the finding of Spiranthcs romanzoviana 

 in County Cork. An interesting discussion on plant-collecting and pre- 

 serving then followed.

NOTES 



BOTANY. 



FERNS. 



Trichomanes radicans in Co. Tyrone. This plant was found 

 j^ear by my brother, Mr. G. G. Delap, Mdthin five miles of Strabane. The 

 locality faces almost west, and is shaded from the sun. There appeared 

 to be three large tufts or plants within a small area. — Rev. Alex. H. 

 Delap, Tamney, (in the Journal of Botany for April). This is a very 

 important and decidedly unexpected addition to the flora of district 10 

 of " Cybele Hibernica." 



ANGIOSPERMS. 



Carex aquatilis in IreIvAND. While botanizing along the banks of 

 the river Main, in Shane's Castle park, in Co. Antrim, in June last, I 

 came across a luxuriant growth of this plant in a ditch of standing water 

 communicating with the river, about a mile and a half from where it 

 flows into Ivough Neagh. This sedge, which was formerly accounted of 

 such extreme rarity in Britain, and which was first obtained in Ireland 

 by Mr. S. A. Stewart, in 1883, in Co. Roscommon, is now added to the 

 flora of district 12 of " Cybele Hibernica." The plant grows very luxu- 

 riantly at the present station, the stems being three to four feet long, 

 and the bracts one and a half to two feet in length. At the mouth of the 

 stream, a mile and a half further down, I observed from the eastern 

 bank an extensive grove of a large Carcx on the opposite shore, which is 

 very possibly the same plant, but had no opportunity of obtaining speci- 

 mens of it. The station above-mentioned is, so far as I am aware, the 

 lowest yet observed for C. aqiialilis in Ireland, being only about fort3--five 

 feet above high tide level. The specimens were kindly determined for me 

 by Mr. Arthur Bennett, F.L.S., who refers them to var. datior Bab. — 

 R. Ivloyd Praeger. 



Vaccinum vitis-idcea AT i.ow^ levels. Commenting on Mr. More's 

 note on this subject in the Journal of Botany for March, Mr. S. A. vStewart 

 writes in the April number of the same publication, that for thirteen 

 years he has known the plant to grow in two stations at Rasharkin, Co. 

 Antrim, one slightly above 500 feet elevation, the other slightly below 

 500 feet.
