ADDITIONS TO '* IRISH TOPOGRAPHICAL BOTANY " 



IN 1901. 



BY R. IXOYD PRAKGBR, B.A. 

 (Read before the Dublin Naturalists' Field Club, 19th November, 1901.) 



A SUMMARY of each 3^ear's additions to the county records of 

 ''Irish Topographical Botany" will, no doubt, be of use and 

 interest to field-botanists, and I present herewith the first of 

 what I trust will be a long series of summaries of the kind. 

 " Irish Topographical Botany " was printed off early last 

 June, but owing to delays in the deliver}^ of the maps, the 

 book was not issued till early August. In consequence the 

 season was practically lost ; otherwise I do not doubt that the 

 lists of blanks filled up in the county floras would have been 

 much larger. I trust that, with the help of the lists of com- 

 moner desiderata which I published in the September and 

 October numbers of this Journal, many of these blanks will 

 be wiped out this year. 



A review of the past season's results shows that, though 

 little systematic field-work was carried out — or at least pub- 

 lished — the year has been by no means unfruitful. A number 

 of interesting discoveries stand out pleasantly, the more so 

 because the announcements have in some cases come from 

 unexpected quarters. The best find of the year is undoubtedly 

 the sub-arctic sedge Carex irrigua, an addition to the Irish flora, 

 gathered in Antrim by Miss Elinor D'Arcy, aged eleven, and 

 shown by Mr. Colgan to be locally abundant round the head 

 of Glenariff". Another Antrim find, of a much rarer species, 

 is that of SpiranthesRoma7izoffLana, our famous North American 

 orchid, already known from Cork, Armagh, and Derr3\ Mr. 

 William West found this near L^ough Neagh, v/hen engaged
