Notes 011 the Flora of Cotmty Dubliii. 285 



Many of the results arrived at] up to the present, whatever 

 their value may be, are necessarily in the nature of dry detail. 

 Some, however, are likely to be read with interest by all who 

 have any practical acquaintance with the county flora, and a 

 short selection from these I now propose to give here, 

 embodying with these more recent observations, a few of the 

 results of many previous years of desultory botanizing in the 

 more picturesque southern or mountain districts of the county 

 These notes may be conveniently arranged under three 

 classes : — 



I. Plants not previously recorded for the county ; II. Recent 

 observations of rarer species recorded only by the earlier 

 writers ; and III. Rarer Co. Dublin species found in new 

 stations.' 



I.— PIvANTS NOT PRBVIOUSI.Y RECORDED FOR CO. DUBLIN. 



Hieracium umbellatum, Ivinn. — Left bank of the Glencullen river 

 in considerable quantity, below the bridge on granite rocks and 

 about half a mile above it on open field-banks. Previously known 

 in many stations in the Co, Wicklow. The Hawkweed flora of the 

 Co. Dublin is extremely limited ; in addition to this vSpecies and the 

 ubiquitous H. Filosella, it includes only one other species, H. vulgaiu/n 

 (Fries) found on the Liffey above Leixlip by Mr. A. G. More {Cyb. Hib. 

 p. I75)--N. C. 



OroJtjanche minor, Sutt. — In abundance, on Trifolitun pratense, in 

 Shennick's Island, Skerries, where it was found and pointed out to 

 me by my brother, Rev. Wm. Colgan, in July, 1893. I am not aware 

 of any previous record for the county. 



Utricularia ncglecta, Lehm.— (i) Quarry hole by the Ward River 

 below Chapelmidway and (2) pools in the Bog of the Ring near 

 Balrothery (Balbriggan) July, 1893. Mr. Arthur Bennett has kindly 

 cleared up my doubts as to the identity of this plant. Added to the 

 Irish Flora by Mr. R. W. Scully from Kerry in 1887.— N. C. 



Carex tcretiuscula, Good.— By the Royal Canal above Clonsilla, 

 sparingly, July, 1893 ; probably carried down by the canal from the 

 inland bogs. — N. C. 



Elcocharis acicularis, (Sm.)— Along the Grand Canal from Hazel- 

 hatch to Clondalkin, in great abundance, September 30, 1S93. Grow- 

 ing in from 3 to 18 inches of water, the abortive spikes conspicuously 

 floating on the surface in the shallower situations. Pre\iously 

 found by Mr. R. LI. Praeger higher up the same canal in Queen's 

 Co. and Co. Kildare (see Ir. Nat. Oct. 1893). The Co. Dublin plant 

 in some of my specimens is fully 94 inches long and is obviously the 

 recognised deep-water form mentioned in Babington's "Manual" (8th 

 Ed. p. 390). In seasons of average rainfall the plant will, no doubt, 

 be found totally submerged in the canal.— N. C. 



To these additions, as I believe them to be, to the county 

 flora may be added the two following, hitherto unpublished,

initials N. C.
