1903- COLGAN. — Fiord of Co. Dubli7i. 187 



♦Sisymbrium pannonicum, Jacq. (5. a//mmww, L.)— First noticed 

 as a ballast plant near the East Wall, Dublin Harbour, in 1894, this 

 East European alien appeared frequently, and in some places in 

 luxuriant growth, along the new tram line between Dollymount and 

 Raheny in 1900, some of the plants growing to a height of 4 feet. 

 In the following year a few seedlings appeared on the same tram 

 line near the end of Long-lane, Sutton. 



*Cardainlne Impatiens, L — About a dozen plants on the top of a 

 shaded wall near Dalke}', 1901-03 ; probably an accidental intro- 

 duction. The habitat is an unusual one. 



* IvEPiDiUM Draba, L. — In profusion, spreading for about 100 yards 

 in waste ground, and on the banks of a railway siding near the mills 

 at Cross Guns, Royal Canal, May, 1903 ; F. C. Crawford & N.C. An 

 alien thoroughl}- established in this station, where it appears to 

 reproduce itself b}^ seed. Previously noted in the county, as a casual 

 only, by Mr. Praeger, near LifFey Junction in 1894. 



Geranium columbinum, L,. — In fair quantity on the limestone rock 

 of Carrick Hill, near Portmarnock, 1900 ; a new station for this rare 

 species. 



•Lotus tenuis, Waldst. and Kit. — One large patch in a fallow field 

 near Donabate, 1901. 



*Sedum album, L. — Abundant on the seaward slope of the railway 

 bank near the tunnel at Vico, spreading from the summit to near 

 sea-level, 1901-03; sparingly on limestone rock at Kirkpatrick 

 bridge above Blanchardstown, 1902-03. Often planted on walls, and 

 apparently becoming naturalised in the county. 



Cai^IvITRIChe obtusangula, Le Gall.— Ditches at Garristown Bog, 

 1894, and at Lusk Ponds, 1902 ; verified by Messrs. H. and J. Groves. 



*Bryonla dioica, Jacq. — Thoroughly established on the cliff or high 

 drift bank below EarlsclifF, south side of Howtli Head, 1902. There 

 are at least a dozen luxuriant plants here, of both sexes, scattered 

 amongst brambles and bushes over a space of 100 yards from east to 

 west. Fruit was abundant here in 1902, and the plant appears to 

 have spread rapidly since it was first observed in this station in 

 1894 by Miss A. G. Kinahan. The fruit is without any obvious 

 special contrivance for distribution ; nor can I discover that it is 

 eaten by birds. If the plant should have been wilfully introduced 

 and spread, it is to be hoped that the offender will make the only 

 amends now possible by publishing a full coufes.sion in this Journal. 



Aplum nodiflorum, Reichb., var repens, Hook, fil.— Abundant 

 in pools in the Bog of the Ring, 1902. 



♦Carum Petroselinum, Benth. and Hook, fil.— In considerable 

 quantity on a bank by the sea, near the Martello Tower at Skerries, 

 1902. 



tChserophyllum temulum, L.— Abundant, and in places luxuriant 

 on hedge banks by the Malahide Creek, from near Lissen Hall to 

 Prospect Point, stretching for about half a mile, 1902 : Dr. Scully 

 and N.C— Bank by the roadside between Lucan and the Royal 

 Canal, 1 895-1903.
