1904. CoivGAN. — Additions to the Flora of Coimty Dublin. 57 



Templeogue plant was the var. JVz^/termgii of the coniuion G. palustre^ 

 so that the present record may fairly be taken as the first for the 

 county. It gives the highest vertical range so far observed for the 

 species in Ireland. In Great Britain it attains to an elevation of at 

 least 1,600 feet. 



Hleraclum murorum, L., var. maculosum, Dahlstedt. — I am 

 indebted to Mr. Praeger for the suggestion that the new Co. Dublin 

 Hawkweed recorded in these pages in July last under the name 

 H. viaculosumf Dahlstedt, might be better named as above, in 

 accordance with the London Catalogue. On re-consulting autho- 

 rities, I find that although Dahlstedt originally described the plant 

 as a species, he afterwards subordinated it as a variety to H. murorum. 

 When comparing my specimens with the description in F. N. 

 Williams's Prodromtis Flor. Brit., p. 136, I extracted by oversight the 

 old synonym instead of the more recent varietal name, which is 

 no doubt better fitted to mark the position of the plant as a 

 member of the complex group, H. nmrortim. He would be a bold 

 man, indeed, who should venture to dogmatise as to the limits of 

 species and varieties in this protean genus, but in the present case 

 it would appear to be the safest course to adopt the varietal name. 

 In cultivation, the conspicuous blotching of the leaves persists, and 

 the Rev. W. R. Linton, having more closely studied the plant, 

 accepts my naming, as he finds the differences between it and 

 Dahlstedt's maculosum insufficient to warrant their separation. It 

 is probably an alien in Co. Dublin ; how or whence introduced does 

 not appear. 



Senecio viscosus, L. — Some fresh Howth records for this rare 

 species have been kindly supplied to me by Miss R. M. Mahaflfy, 

 who found it between the Bailey Lighthouse and Sutton in 1900, 

 and on Sutton beach in the present year. Though now extremely 

 rare, this species has held its ground in or around Howth for at 

 least TIG years. 



*IVIatrIcaria occldcntalls, Greene. — In the first record of the 

 appearance in Ireland of the interesting alien, Matricaria discoidea 

 DC. (Jr. Nat., iii., 215), attention was drawn to the two very distinct 

 forms in which it occurred in Co. Dublin— one, the common form, a 

 low, procumbent, much-branched plant, with small flower heads 

 and entire seed crown ; the other, upright and more robust, with 

 large heads and toothed seed-apex. This latter plant, described in 

 Asa Oray's Synoptical Flora of North Atnerica, 1886, and, apparently with 

 good reason, constituted a species by E. L. Greene, appears to be 

 spreading in Ireland, though still rare. In 1902 I found a few 

 vigorous plants growing in waste ground by the Grand Canal below 

 Hazlehatch, its third station for Co. Dublin. Dr. Scully has already 

 recorded it for N. Kerry (Jr. Nat., xii., 114). It would be of interest 

 to have further details of its Irish distribution, as it is likely to 

 occur sparingly wherever M. discoidea is found. In California,
