196 NATTTKAL HISTOKY SOCIETY OF DUBLIN. 



JEgopodium podagraria. — On the roadside at Glassan, county of 

 Westmeath. This umbellifer, though very abundant in the north, ia 

 not much known in the south or midland counties. 



Viburnum opulus. — The Guelder Rose is very plentiful in shady 

 woods and hedges, and on wooded crags, all through the midland 

 counties. 



Galium loreale. — This very local plant grows in rank luxuriance 

 among the shingle on, the snores of Lough Ree, in the counties of 

 Westmeath, Longford, and Roscommon, associated with Rubus saxatilis 

 and Thalictrum minus, the three giving a thoroughly natural stamp to 

 the Flora of the place. It also grows sparingly at Lough Gara, county 

 of Roscommon. 



Tanacetum vulgare. — Near Ballymore and Mullingar, county of 

 "Westmeath ; also sparingly in the neighbourhood of Longford. 



Pyrethrum parfhenium. — Sparingly in the neighbourhood of Long- 

 ford. Resides these I did not meet with any of the rarer Compositse. 

 Senecio jacobcea varies considerably according to situation; and Senecio 

 viscosus is not uncommon on the edges of bogs. 



Digitalis purpurea. — On other occasions I have alluded to the oc- 

 currence of Digitalis in limestone districts. It grows abundantly all 

 through the midland counties. A pure limestone soil is unfavourable 

 to its welfare, but it prospers well on impure cherty and earthy lime- 

 stone ; in fact, a certain percentage of lime does not injure it.* I have 

 observed that Blechnum spicant, also avoiding pure limestone, is fre- 

 quently a cohabitant of Digitalis. A pure limestone soil is not more 

 deleterious to Digitalis than it is to the Ericaceae and several Ferns. 



Scutellaria galericulata. — Tolerably abundant in woody places on 

 the shores of Lough Erne, county of Westmeath. 



Utricularia vulgaris. — In watery ditches near Castlepollard, county 

 of 'Westmeath ; it is an excellent plant for an aquarium, being both 

 ornamental and easily grown. 



Lysimachium vulgare. — 3Tot common. It occurs on the south-east 

 shore of Lough Ennel, and also in meadows on the banks of the Inny, 

 associated with Thalictrum flavum ; also at Lough Key, county of Ros- 

 common. 



Polygonum bistorta. — I met with this rather rare plant growing 

 pretty freely on the banks of the Suck, near Rallinasloe, in the same 

 place as Prunus padus above mentioned. 



Salix pentandra. — The Bay-leaved "Willow, perhaps the most beauti- 

 ful of the Amentaceas, is not uncommon along the banks of the Suck, 

 near Ballinasloe. 



* Benbulben and tbe mountains about Glencar, near Sligo, are good instances of 

 this. They are composed of dark grey or black earthy limestone, with bands of shale and 

 nodules of chert, and occasional beds of purer limestone. Digitalis grows all orer them 

 in the greatest abundance.
