and due to the researches of my friends, Rev. C. F. d'Arcy 



and Mr. R. W. Scully. 



Scutellaria gralericulata, lyinn. — Found by the Royal Canal below 

 Lncan station, sparingly, circa 1887, by Mr. R. W. Scully, who has 

 shown me specimens from this locality. I am on the whole 

 inclined to agree with H. C. Hart in holding that Wade's record for 

 this species : " In the marshes of Howth " {PL Rar. 1804) should be 

 transferred to S. minor which I have gathered fully twelve years ago 

 on Howth Head in one of the stations given by Mr. Hart. If this 

 revision of Wade's record be correct, Mr. Scully's station becomes 

 the first county record for S. galericulata. 



Polypodium Phegoptcris, Linn. — Found on damp shaded rocks on 

 Secawn mountain, Glenasmole, circa 1883, by Rev. C. F. d'Arcy, who 

 soon afterwards showed me the plants growing there. Perhaps this 

 species and Osmunda regalis, recorded from Howth by Mr. H. C. 

 Hart, are now amongst the rarest of the Co. Dublin ferns. 



II.— RECENT OBSERVATIONS OF RARER SPECIES RECORDED 

 ONLY BY THE EARLIER WRITERS. 



Corydalis claviculata, DC. — On a granite tahis in Glenamuck near 

 the Scalp, 1882. This is the only Co. Dublin station in which I have 

 seen the plant, and I can find no other county records more recent 

 than those in Flora Hibernica (1836). — N. C. 



Bidens cernua, Linn. —Abundant in the Bog of the Ring south of 



Balrothery (Balbriggan) July, 1893.— N. C. 



B. tripartita, Linn. — Abundant at the pond near Balrothery known 

 as the Lough or Knock pond, July, 1893. The pond had become 

 very much reduced in size by the extreme dryness of the year, and the 

 Bidens appeared growing in a stunted form stranded many yards from 

 the water's edge. So far, I have found this and the preceding species 

 only in the stations here given, and though both appear to be very 

 rare in the county, I can find no definite localities for either later 

 than Wade's (1794). 



Lysimachia vulgaris, Linn. — In small quantity in an old quarry by 

 the Delvin river nearly opposite StamuUen in the extreme north of 

 the county, July, 1893. Hitherto this species could only claim a 

 place in the Dublin flora on the faith of the old record : " about 

 Loughlinstown and Old Connaught" in the Irish Flora {\'^2)'h)' ^^ 

 this station it has not, I believe, been seen for very many years. — 

 N. C. 



Ruppia spiralis, Hartm. — Tidal river-reaches near the head of the 

 Malahide estuary, abundantly, in two stations (i) near Lissen Hall 

 at the mouth of the Broad Meadow Water, and again (2) about a mile 

 to the eastward near Newport House, July, 1893. These appear to 

 be the first definite localities for this plant in the county, the only 

 previous mention I can find of it being the reference in Cyb. Hib. 

 (p. 316) to a specimen labelled in Dr. Mackay's Herbarium "near 

 Dublin, &c."— N. C. 



Hydrocharis IVIorsus-ranae, Linn. — This species, now very rare in 

 the county, though probably much more plentiful before the low- 

 lying bogs were drained, I found in three stations in July, 1893 : 

 (i) the Bog of the Ring, (2) Curragha Bog, and (3) the Broad Meadow 

 Water near the old church of Killossory. In the first two stations it 

 grows in abundance, but only very sparingly in the third. As regards 

 station 2, given in Wade's Planta Kariores (1804), the difiiculty is 

 rather to find the bog than the plant ; for drainage has reduced this 

 favourite hunting-ground of the earlier botanists to one deep pool 

 about 50 feet long by 15 wide and a couple of ditches adjoining.
