294 The Irish Naturalist, November, 



eight species not in Clare, against four in Clare not in Bofin. 

 In Vascular Cryptogams Clare is far ahead of Bofin, having 

 twelve peculiar plants against two, eight of the twelve being 

 ferns. 



The rarest Bofin plants not in Clare are Helianthemuni 

 gzittatuvi, Calamagrostis Epigejos, Eriocaiiloji septa7tgularey and 

 Isoetes echi7iospora. As regards the first of these, it may 

 possibly occur on Clare Island. Our visit took place shortly 

 after the break-up of very unusual drought. The vegetation 

 of dry spots had got utterly parched, and its remains were 

 now covered with a fresh growth of late plants ; so that small 

 plants of dry places ran much risk of being missed. 



Of the plants found on Clare Island, thirteen are additions 

 to the flora of Division 27, West Mayo : — 



Cochlearia danica. Beta maritima. 



8 Silene acaulis. 8 Atriplex hastata. 



8 Saxifraga decipiens. Polygonum Raii.^ 



8 Arctium Newbouldii. Agropyron repens. 



8 Hieracium liypochseroides. Aspidium aculeatum. 



8 Lamium hybridum. Ophioglossum vulgatum. 



Equisetum maximum."" 



Of these, the six marked "8" are additions to the flora of 

 District viii. of Cybele Hibernica. 



The following additional species had only one previous re- 

 cord from West Mayo ; — 



Fumaria confusa. Leoutodon hirtus. 



Sagina maritima. Stachys arvensis. 



Spergularia rupestris. Festuca rottboeUioides, 



Rubus pHcatus. Bromus commutatus. 



Crithmum maritimun, Asplenium marinum. 



Filago germauica. Nitella translucens. 



My best thanks are due to Messrs. Arthur Bennett, H. and J. 

 Groves, B- F. Linton, W. G. Pugsley, W. Moyle Rogers, and 

 P'rederick Townsend, for their kindness in naming critical 

 plants. 



■■ Since the above was written these two plants have been recorded 

 from West Mayo by myself {supra, p. 269) from the mainland near 

 Clare Island.
