there by Barringtoii and Vowell were kindly submitted to Rev. K. F. 

 Liuton by Miss Knowles. One plant, labelled H. casiiini var. Smithii, 

 from Ben Rulben, ]\Ir. Linton identifies as //. ciliatnm var. rcpandii»i 

 Ley. In Barrington and Vowell's report, //. ccesiiin: var. Sviithii is 

 recorded from Ben Bnlben and from Goat Island, Lough (xill. The 

 Lough Gill specimen is not forthcoming, but as the same specialist 

 named both, it would seem that both stations had better l)c trans, 

 ferred. //• (■i/ia/ii/u has not been recorded from Ireland hitherto. 



Hieracium Schmldtii, Tausch. — The only specimen of Barrington 

 and X'owell's H. palUduui {H. Schniidtii), which they collected in three 

 stations, INIr. Linton refers to i¥. aiigliciini\ so it appears doubtful if 

 this plant grows in the Ben Bulben district. 



Potamogcton Kirkii, vSyme.— /V^rw^^'t-Av/ /wV/vV has long been known 

 as growing in the Bealanabrack River, close to the bridge at INIaam, 

 and has been frequently collected there. The Bealanabrack River 

 flows into the long north-western arm of Lough Corrib. It sinks to 

 lake-level above INIaam, and thence flows with a slow deep course, 

 some 50 feet wide, for a distance of a mile, when it] suddenly widens 

 into the lake. Up to Maam the river is navigable, and a small 

 steamer periodical!}' ascends to the plant's habitat to discharge 

 passengers and goods. Two other localities which appear in Fryer's 

 " Potamogetons of the British Isles,"' p. 18, 1898, invite discussion. 

 The paragraph dealing with the distribution of this supposed 

 In'brid, in the work referred to, reads as follows ; — 



"Localities: At present this hybrid-species is only known from 

 Ireland, where it was " found by Mr. Thomas Kirk, in the Ballina - 

 brack River at Maam, co. Gal way' (Syme), ' Loch Xeagh by Dr. I). 

 IMoore." Lough Corrib, Galwa}', T. Kirk, Sept. 7th, J854.'' 



Correspondence with ^Nlr. Fryer elicited the facts that the Lough 

 Xeagh record was based on a specimen in the Edinburgh Herbarium, and 

 the Lough torrib record on two specimens in Mr. Charles Bailey's Her- 

 barium, Professor Balfour and ^Nlr. Bailey both kindly acceded to my 

 request to send their sets of P. Kirkii to Mr. I'ryer for re-examination, 

 and at the same tmie Miss Knowles assisted by forwarding the contents 

 of the P. Kirkii cover in the National Herbarium. Professor Balfour was 

 so good as to send the Kdinburgh sheets to me in the first place. ]Mr. 

 Fryer has now critically examined the whole series of plants, and both 

 he and I have paid particular attention to the labels which accompany 

 them. 



As to the Maam station there is no doubt, but it comes into the question 

 in this way. Thomas Kirk, the discover of the plant, on all the labels 

 written by him which have been examined (namely, two in Bailey's 

 Herbarium, two at I\dinburgh, and three in Dublin), quotes the station 

 as simply *■ Lough Corrib." Maam is not mentioned, though it was 

 certainly intended in at least some cases, as Kirk is well known to have 

 been the finder of the plant in its classical Maam station. {See £/;^/7s/i
