1906. Vra.v.gv.'r— 071 the Botany of Lough Carra, 209 
Pla7iia^o luaritivia, Sesleria ccsrtdea, Selaginella selagmoides . 
To these he added, in the first edition of " Cybele," Rtibiis 
saxatilis, A'osa Sadi?ii, and Epipactis palustris ; and in the 
same work Ophrys apifcra is recorded, on the authority of 
Miss lyindsay. Lastly, Mrs. D. D. Persse collected a good 
deal in the Ballinrobe district in 1892-4, and kindly allowed 
me to take notes from her herbarium when I was gathering 
material for " Irish Topographical Botany." The rarer Lough 
Carra plants included in her collection were Thalictrum 
collhmm^ Gentiaiia venia^ Salix pentandra^ Jitnipertts communis^ 
Spiranthes auturmialis^ Ophrys apifera. This appears to 
exhaust our previous knowledge of Lough Carra botany, save 
for Rtibus cceshis, published by Focke,^ as collected there by John 
Ball in 1837, and Ophrys vmscifera and Lastrea Thelypteris, 
given in " Cybele Hibernica " (ed. II.), as found at Lake View 
by Miss Jackson in 1894-6. 
Towards the end of last July my wife and I spent four days 
at Lough Carra. By the kindness of Mr. Stanhope Kenny, of 
Ballinrobe, we not only found comfortable quarters close to 
the lake in the house of Mr. P. J. Loughlin, but had a boat at 
our disposal, which was an invaluable aid to botanical work. 
Three days were spent on the water, visiting the islands, 
points, and bays, while on the fourth we cycled round the lake, 
to gain vSome idea of the flora of the adjoining country. The 
following notes convey our impressions of the vegetation, and 
give particulars concerning the rarer plants observed. 
Zones of Vegetation.— On the shores of the lake, and 
particularly upon the islands, the zoning of the vegetation is 
very marked. Four zones are present, each with a charac- 
teristic flora. They may be distinguished as follows : — 
1. Woodland zone. 
2. Sesleria zone. 
3. Schaenus zone. 
4. Scirpus zone. 
Scirpiis zone. — To take the lowest first. This extends from 
water-level to some feet below it, and is characterized by 
patches of Scirpus lacustris and Phraginites co7?wiunis. As al- 
ready mentioned, water-plants are quite rare, especially in the 
^ List of the British aud Irish Rubi iu the herbarium of the late Mr. 
John Ball, F.R.S. /ouni. Bot., xxix., 162-163. ^^91-
