The Flora of Cotmiy .Imiai^h. yj 



are still unrecorded from the county, a few of the most likely are 

 Arabis hirsuta, Hypericum clodes, Geranium lucidum, Gcntiana 

 campestris, Salix rcpeus, Habenaria bijolia, Ilymenophyllum 

 wilsoni ; the first four of these maybe expected in the lime- 

 stone district. 



A few rare species recorded from the county I failed t(j 

 re-find. Of these, several have (or had) their habitat on the 

 shores of lyough Neagh. There can be little doubt that the 

 drainage works, completed about 1855, which reduced the 

 mean level of the lake by some three feet, and the winter 

 floods to a greater extent, are the cause of the disappearance 

 of some of these previous inhabitants. To this change is 

 probably due the apparent absence now of Szcb2tlaria aqicatica, 

 Elatine hydropiper^ and Pilularia globulifcray and I am inclined 

 to set down to the same cause the disappearance of Lathyrus 

 pahistris, Cladium 7nariscus, Carex eloiigata, and C.filifortnis, on 

 the adjoining Antrim shores of the lough, and possibly also of 

 Carex buxbaumii, and of Calamagrostis hookeri in some of its 

 stations.
