New Plants for North- Western Counties. 



Brief trips in the north-west at the end of last June and in August, 

 though their main object was not botanical, yielded a number of plants 

 unrecorded for their respective counties, which may be worth recording.

Two additional notes are worth quoting : — Orchis mascula — summit o 

 Keshcorran, 1,163 feet. Linaria Cymbalaria — grows on small rocky islets 

 on Lough Gill, such as Goat's Island, amid a purely native vegetation.

Calcifuge Plants on Limestone. 



Last June, in Co. Sligo, I noted a strongly calcifuge flora, including 

 Hypericum hnmifiisum, Cytisus scoparius (abundant), Galium saxatile. 

 Digitalis purpurea, BL'chnum Spicant, and Athyrium Filix-fcemina, growing 

 on the drumlins which lie along the south base of Keshcorran. 

 These drumlins rest on the limestone, and are apparently composed of 

 the debris of the limestone. No other rock occurs within several miles.
