Mr. J. Ball's Botanical Notes of a Tour in Ireland, 33 



on the basaltic rocks at the south-east angle of the hill. 

 Under bushes at the east side I found Circcea intermedia 

 very luxuriant both in flower and fruit, as likewise Vicia syl- 

 vatica, &c. At Colin Glen, a few miles from Belfast, I gathered 

 specimens ofRubus saxatilis; and in boggy ground, about half 

 way up the Glen, a single specimen of a fern which corre- 

 sponds accurately with Smith's original specimens of Nephro- 

 dium cristatum (N. callipteris, DC). Nearly in the same 

 place I collected Mentha rubra and a Galium, apparently of 

 the palustre tribe, but without flower or fruit, remarkable for 

 the leaves in the whorl being constantly four in number. In 

 ascending from the lower woody part of the glen to the rocks 

 at the summit, the botanist can scarcely faU to remark the 

 gradual transition from a very divided form of Aspidium an- 

 gulare through the fonns named aculeatum and lobatum, to 

 one on the rocks above, which cannot be distinguished from 

 A. lonchitis^. Throughout a great pai-t of Antrim I noticed 

 Rubus Id(ms as the most common species of the genus in 

 hedges and w^oods as also on rocky ground. 



At Coleraine in Derry, Carum verticillatum is found in great 

 abundance by the west bank of the river about a quarter of a 

 mile below the town. In a potato field near the same place 

 I found Lamium intermedium, which is new to the Irish Flora; 

 I also found it in a similar situation near the foot of Ben Bul- 

 ben in Sligo, and it is probably not rare in the northern coun- 

 ties. On sandy ground, near the mouth of the Baun, I no- 

 ticed G'naplialium minimum and rectum, and Trifolium medium, 

 I may direct the attention of the conchologist to the sandy 

 coast of MagiUigan, which is very productive in marine shells. 

 In addition to many rare plants mentioned in the Flora Hi- 

 bernica as growing on Ben-ye-venagh, I found many alpine 

 species not common in Ireland, Silene acaulis, Dry as octope- 

 tala, Sawifraga hypnoides, Salix herbacea ; and on Umbragh 

 rocks Rubus saxatilis. Throughout the counties of Derry, 

 Tyrone, Donegal, and Shgo Galiopsis versicolor is common ; 

 but I may observe as somewhat remarkable, that I have never 



* In this glen some rare land shells, Helix fusca and scarburgensis (lamel- 

 lata, Drap.), are to be found : for the direction to this spot 1 am indebted 

 to that active naturalist Mr. Thompson of Belfast.
