grandiflora in Clare, if the plant prove to be indigenous there, 

 is the most important of these. Rosa hibernica, extended from 

 Down to Limerick, is another interesting find, though, in view 

 of the English distribution of the plant, not surprising. Mr. 

 Stewart's discovery of Juiicus temds near Belfast shows that 

 this interesting rush is not confined to south-western Ireland, 

 as formerly appeared. Dr. Scully's Killarney record of Rubus 

 argentatus supplies a second station for a bramble hitherto 

 found only in E- Mayo. The rare British-endemic Hieracium 

 hypochceroides^ long known in Ireland only from Clare, and 

 recently found in W. Cork, is now extended northward to 

 W. Mayo. Several plants which we associate with the southern 

 half of Ireland, such as Geraniutn cohimbimim, Valerianella 

 Auriaila, ChcJiopodium rubftim, and Carex divulsa, have been 

 pushed northwards into Down. Silene acaulis has been ex- 

 tended southward, and Saxifraga decipiens northward, into 

 W. Mayo. 



The plant on which rested the Down record of Hieracium 

 sciaphilum, is now referred (Watson Bot. Exch. Club Report, 

 1902-3) in part to H. 7nurorum var. pellucidum and in part to 

 H. diapha7ioides, the latter of which is unrecorded for Ireland ; 

 but Mr. Waddell recommends a postponement of the accept- 

 ance of this transfer till a further series of the Rowallane plant 

 has been gathered and reported on. 



The records for the past year include several critical plants 

 and aliens that now claim admission to the Irish list, as given 

 in Irish Top. Bot. As regards critical plants, Fumaria pur- 

 purea Pugsley must take its place alongside the other segrates 

 of the Capreolate Fumitories. Arctium Newbouldii Ar. Benn. 

 must also be inserted. Mr. Bennett's view (see I.N., xii., 289) 

 is that British Burdocks must be listed as A. majus^ A. inter- 

 medium Lange {= A, ne7?iorosum Lej.), A. fninus^ and A. New- 

 bouldii Ar. Benn. (= A. 7ie?no7'osum Bab.) Whether or no ^. 

 i7iter77iediu77t and A. 7iemorosu7n be combined. A- Newbouldii 

 should be distinguished and its distribution worked out. 



As regards aliens claiming naturalization, I wrote in Irish 

 Top. Bot. (p. xcv.) — " Alien plants naturalized in only one 

 locality are usually omitted . . . since their present claim to 

 admission to the flora ma}^ depend on local and temporary 

 influences." Several species thus excluded in Irish Top. Bot.
