Notes on the Flora of County Dublin. 287 



Both pool and ditches, however, still nourish abundance of this 

 interesting species. This station very narrowly escapes being in the 

 Co. Meath, but careful study of the map and the aid of an intelli- 

 gent resident farmer, who traced out for me the actual county 

 boundary, set it beyond all douljt that this last remnant of the Cur- 

 raglia ' Bog is in the Co. Dublin. — N. C. 



Malaxis paludosa, Sw.— On Glendhu mountain in considerable quan- 

 tity, growing on a level stretch of living Sphai^'num at a height of about 

 1,500 feet, July, 1884; the only station in which I have found it in 

 the county. Mr. John Bain, the veteran of Irish botanists, assurecl 

 me in March last that he had gathered Malaxis in great abundance 

 at the head of Kelly's Glen- both before and after the publication of 

 the Flora Hibernica (1836). The plant does not appear to have 

 been observed there recently. So well does its small size and quasi- 

 protective colouring enable Malaxis to elude discovery that I have 

 met with more than one botanist of wide experience who has never 

 had the good fortune to ^ee the plant growing. — N. C. 



Hymenophyllum Wilsoni, Hook.— Sparingly on one of the upper 

 forks of the Dodder River, Glenasmole, where it was pointed out to 

 me by Rev. C. F. d'Arcy in 1883. This seems to be the locality set 

 down, in error, no doubt, in the Irish Flora (1833) for H. Tun- 

 bridgense. 



III.— RARER CO. DUBIvIN SPECIES OBSERVED IN NEW 



STATIONS. 



Nasturtium palustre, DC— (i) The Ivough, Balrothery, (2) Bog of 

 the Ring, (3) near Baldwinstown cross-roads, and (4) north of Lusk, 

 July, 1893 (for all stations). — N. C. 



Senebiera didyma, Persoon — Roadside at Kilmacud about one mile 

 west of Stillorgan, but not abundantly, October, 1892. Very rare in 

 the county. — N. C. 



Hypericum hirsutum, I^inn. — Hedgerows near Drimnagh, a few 

 plants, September, 1892. — N. C. 



Trifolium fragiferum, Linn. — (i) Shore south of Raheny, abun- 

 dantly, 1892 ; (2) marshy hollows by the Grand Canal, Hazelhatch, 

 1893, and (3) by the River Tolka, near Mulhuddart, 1893. The inland 

 stations 2 and 3, distant respectively twelve and eight miles from the 

 nearest sea, are interesting from their position, as the species, in Ire- 

 land, at least, appears to have a decided preference for the coast. — 

 N. C. 



"^Linaria minor, Desf. — Abundantly along the railway line from 

 Clontra to Bray river, September, 1893. Also noted this year by Mr. 

 R. Ivl. Praeger in abundance along the railway at Foxrock. A species 

 which spreads very rapidly along railways, growing by preference in 

 the ballast.— N. C. 



IChcnopodium rubrum, Linn.— (i) Wet ground by the Ward River 

 near Chapelmidway, July, 1893, (2) banks of the Grand Canal at 

 Hazelhatch, September, 1893, and (3) by the watercourse connecting 

 the upper and lower ponds of Brittas, October, 1893. Well estab- 

 lished in all three stations ; certainly introduced by traffic in (2) ; pro- 

 bably a farmyard outcast in (i); and most remote from dwellings 

 in (3). Very rare in the county. — N. C. 



1 Pronounced Curragh-ha by the peasantry of the district. 



"^ The Upper Dodder valley, now, and, as I believe, always known to 

 the inhabitants as Glenasmole. I have many times inquired for Kelly's 

 Glen from natives, young and old, of the Upper Dodder valley, and have 

 been invariably referred to the valley lying some three miles farther to 

 the N. E. between the Kilmashogue and Tibradden mountains.— N. C.
