rhceas is plentiful in fields at the same place. Only pre- 

 viously recorded habitat in Ulster is along the Down shore 

 of Belfast Lough, where it has been known for nearly a 

 century. 

 XBarbarea prcecox, R. Br. Cultivated ground at Struell Wells, 

 near Downpatrick, R.L1.P., 1891 (Jide A. Bennett). New 

 to District 12, the plants recorded under this name in 

 "Flora Belfastiensis " being referable to B. intermedia. 

 Lavatera arborea, Linn. Growing in some abundance near the 

 summit of Stackaniskan, an isolated sea-stack, rising about 

 100 feet above the water at the western end of Rathlin 

 Island ; R.L1.P., June, 1892. Stackaniskan stands about 

 100 yards from the shore, and can only be approached by 

 boat in calm weather ; the habitat of the tree-mallow is 

 quite inaccessible, and I do not see how the plant can have 

 been possibly introduced here. It grows sparingly on the 

 cliffs of the mainland further northward, but I did not ob- 

 serve it in any cottage garden on the island. (See Irish 

 Naturalist, 1893, p. 53.) 



Hypericum quadrangulum, Linn., var. maculatum, Bab. Side 

 of the lane leading from Marino Station to Cultra Garden, 

 Co. Down, R.L1.P., August, 1892. Only previous record 

 in district 12 is in Co. Antrim, by the Lagan, a few miles 

 above Belfast. Mr. J. H. Davies has recently found it at 

 Glenmore, near Lisburn, further up the same river. 



Geranium pyrenaicum, Linn. Roadside, near Whitewell Quar- 

 ries on Cave Hill, W. D. Donnan. Not hitherto recorded 

 from Co. Antrim. 



Erodium cicutarium, L'Herit. Observed on the Field Club 

 Excursion to Binevenagh, Co. Derry, July 30th, 1892, in 

 several spots along the base and summit of the cliffs (800 — 

 1,200 feet circa) growing among Si/ene acauhs, S. mari- 

 tima, Dry as octopeta/a, Salix herbacea, and other al pines. 



t hrunus cerasus, Linn. Not uncommon in Down and Antrim, 

 but often in suspicious situations. Near Crossgar and 

 Downpatrick in Down, Cushendun and Ballycastle in 

 Antrim, and Draperstown in Derry, R.L1.P.
