56 The Irish Naturalist. 



Festuca myurus, Ivinn.— A few tufts on a wall top near Lispopple 

 cross roads, August, 1894. Very rare in the count}', the only other 

 recorded stations being Howtli and Donnybrook, in the latter of which 

 it was gathered by ]\Ir. A. G. More in 1878. 



Lastrea Orcopterls, Presl. — This fern, so abundant in parts of 

 Wicklow, seems extremely rare in Dublin. A single plant only rewarded 

 my search in the Dublin Mountains this j-ear (September, 1S94), and as 

 this grew directly on the Dublin and Wicklow boundary S.W. of Glen- 

 cullen Bridge, it is not without hesitation I give it a place here. M)' 

 friend, Revd. C. F. d'Arcj% who is thoroughly acquainted v/ith the Dublin 

 Mountains, and has made a close study of their ferns, tells me he found 

 a single plant on Glendhu Mountain in or about 1880. 



Botrychlum Lunaria, Sw.— (i) Verj' abundant on the summit 

 (1,250 feet), and down the northern slope of Montpelier at intervals to 

 700 feet. May, 1894 ; (2) Pastures near the shore below the monument 

 (round tower) at Portrane, April, 1894, Still frequent in Mackay's old 

 station, Kelly's Glen or Glenasmole [Cat. 1S06) in the upper portion of 

 which Mr. Greenwood Pim tells me he found it in 1889, while Dr. 

 M'Weeney two years later gathered it lower down the-glen near Friars- 

 town. 



Ophiogrlossum vulg-atum, Linn. — (i) Frequent in damp pastures 

 above Gormanstown woods, April, 1894 ; (2) Marshy fields near 

 Dunsoghly Castle, abundant. May, 1894 ; (3) Near the head of Crooksling 

 Glen, above the Slade of Saggard, at 650 feet, June, 1894. Mr. W. H. 

 Bloomer has shown me a specimen gathered by him near the monument 

 at Portrane in April, 1894, and Dr. M'Weeney informs me that he found 

 the plant abundant in 1891 along Glenasmole, from a little above 

 Friarstown to the head of the valley. Near Friarstown, I found it in 

 great profusion and luxuriance on the 24th June last. Appears more 

 widelj' distributed in the county than the preceding species, as it is now 

 on record from seven out of the eight districts into which I have divided 

 the county for botanical purposes. 



Lycopodium clavatum, Linn. — In great abundance and fruiting 

 freel}' on the flat mossy summit of Slieve Thoul, near the S.W. extremity 

 of the county at a height of 1,300 feet, August, 1894. I'erhaps no 

 observ'ation of last season was more satisfactory to me than this, as a 

 25 years close acquaintance with the Dublin Mountains had failed to 

 give me a single station for this interesting species. Loosel}^ and 

 inaccurately set down in Mackay's Catalogue, 1824, as plentiful in the 

 Dublin Mountains, and recorded in the Irish Flora, 1833, from Kelly's 

 Glen and Ballynascorney. 



In concluding these Notes I wish to express my indebtedness 

 to Mr. A. G. More and Mr. Arthur Bennett for assistance in 

 determining some of the critical forms referred to. Information 

 of further stations for any of the rarer County Dublin species, 

 I shall be ahvaj^s glad to receive, as well as any reference to 

 records, whether in the shape of manuscript, printed matter, 

 or herbaritim plants, likely to throw^ light on the history of 

 the county flora.-'' Notes of new stations for rare or critical 

 plants vShotild, if possible, be accompanied by specimens.
