ii6 Guide to Belfast. 



In the following list, brackets refer to plants not recently 

 seen, and which may be extinct on Lough Neagh owing to 

 this cause ; the letter E is prefixed to plants apparently 

 extinct on that portion of the lake which belongs to Down 

 or Antrim : 



Ranunculus circinatus. E. Lathyrus palustris. 

 (Subularia aquatica.) (Slum latifolium.) 



(Elatine Hydropiper.) (Carex elongata.) 



Rhamnus Frangula. (C. filiformis.) 



(R. catharticus.) E. Pilularia globulifera. 



The Antrim mountains present great stretches of bog 

 of from 1,000 to 1,500 feet elevation. This ground yields 

 Carex paiicifiora and C. irrigua, both unknown elsewhere in 

 Ireland ; also Saxifraga Hirculus. On less elevated bogs, 

 Utricularia intermedia., Malaxis paludosa, and Eiiopliorutn 

 latifolium have their only stations in the district. On the 

 eastern side the plateau presents a precipitous escarpment 

 towards the sea, carved into deep glens. On these cliffs of 

 basalt grow many of the plants characteristic of the Antrim 

 flora : 



Arenaria verna. Saxifraga hypnoides. 



Vicia Orobus. Hieracium iricum. 



Dryas octopetala. Orobanche rubra. 



Others haunt the slopes and deep glens : 



Geranium sylvaticum. Melampyrum sylvaticum. 

 G. pratense. Equisetum pratense. 



Pyrola secunda. 



The basalts supply to a certain extent the requirements of 

 the calcicole plants, without excluding the species of calcifuge 

 proclivities, and the flora of Antrim is therefore not so dis- 

 tinctly calcifuge as that of Down. Still, of the ten '■^calcicole A" 

 plants of Cybele Hibernica, only three occur: — Geranium 

 lucidum is widely spread ; Orchis pyramidalis grows on 

 chalk rubbish near Lisburn (the only limestone plant, 

 apparently, brought in by the girdle of Chalk which fringes 

 the basalt escarpment) ; Carlina vulgaris occurs sparingly 

 on sea-sands, as in Down. Of ^''calcicole B" plants, all the 

 species already listed for Down occur, except the introduced
