COMPOSITE. 81 



Neagh ; G. C. Hyndman. Ditches at Lambeg ; Flor. Uht. 



By the Bann at Portglenone ; S.A.S. Antrim ; D. Redmond. 

 Deny — Enagh Lough, and many parts of the county ; D.M. 



The form with radiant flowers {B. radiata), has been found at Bally- 

 go wan in Down, and Portmore in Antrim. 



ARCTIUM Linn. Burdock. 



The distribution of the segregate forms of this genus has not been fully, 

 and certainly ascertained. When the plants are well developed they are 

 sufficiently distinct, but only such can be relied on, and all notes based on 

 imperfect, or immature specimens must be discarded, and also notes by 

 botanists who have not specially studied the group, unless fortified by 

 satisfactory examples. The records which follow are meagre, but they 

 have been fiated by high authority. 



[A. MAJus SchTiur. A plant collected by S.A.S. , in Rathlin, was con- 

 sidered by Prof. Babington to belong here, but as only one specimen was 

 gathered, and that not as good as might be desired, it is advisable to leave 

 it for future research. The note on this species in Flor. Belf. is of no 

 authority.] 



1. JEL, nemorosuzu Lej. 



Gravelly and sandy waste ground — frequent ? Fl. latter end of July, 

 mature in Aug. 

 Down— Near Donaghadee, and gravelly pastures on Rough Island, above 



Newtownards ; S.A.S. 

 Antrim — Quarry spoil-bank at Magheramome, very fine ; S.A.S. 

 Derry — Roadside at foot of Benevenagh east of Bellarena station ; S.A.S. 



2. A. intermedium Lmige. 



Roadsides, and waste ground— frequent ? Fl. July and Aug. 

 Down — There is little doubt of its occurrence in the county, but authora- 



tative specimens have not been localised, and special stations 



cannot be quoted at present. 

 Antrim — Coast of Antrim ; Prof. P. Tate. Roadsides at Antrim, and 



common on Rathlin Island ; S.A.S. About Belfast, and other 



places in Antrim ; Gyb. Hib. 

 Derry — Uncertain. 



[A. MINUS Schkur. Plants which seem to be this form have been col- 

 lected, but they are not sufficiently mature, and may belong to the pre- 

 ceding species. The plant of Flor. Belf. was not certain.]
