Notes on the List. 



Fumaria confusa, Jord. — Both the type and var. hibernica, Pugsley, occur 



sparingly. 

 Cardamine pratensis, L. — The forms with proliferous leaves and with double 



flowers both occur. 

 Cochlearia groenlandica, L. — Not uncommon in chinks of rocks at the west 

 end. Found also on Inishturk, Inishbofin, Achill, and in north Donegal. 

 Polygala vulgaris, L. — Only found on the great cliff, among alpines — a hand- 

 some dwarf form, with very large leaves and flowers. Mr. Arthur Bennett 

 writes of it : — " It is very like specimens I gathered on the cliffs of chalk 

 at Dover, and when I gathered it I thought I had found grancliflora. . . . 

 It certainly seems to me to come at least half way between that and the 

 eu-vulgaris of Syme, and is a notable form." 

 Silene acaulis, L. — Varies much in the colour of its flowers, from pale pink to 

 deep rose and dull purple. The Clare Island station is the most southerly 

 in Ireland, and its lower limit here (400 feet) is the lowest in the 

 country — lower even than in Donegal (550 feet). 

 Sagina subulata, L. — Eocks near the harbour, also near the light-house, and 



frequent at the west end. Was found also on Achillbeg. 

 Lychnis diurna, Sibth. — A very rare plant in the west. On Clare Island there 

 is a colony of it on the cliff on the north side of Knocknaveen, and 

 another on the Croaghmore cliffs at 800 feet. Its only other West Mayo 

 station is on Inishturk. 

 Spergula arvensis, L. — Both forms (vulgaris and sativa) common. 

 Montia fontana, L. — Var. minor common ; var. rivularis only once seen. 

 Alchemilla vulgaris, L. — Bare on the island. A. alpestris Schm. was the 



prevailing form, but A. pretensis Schm. also occurred. 

 Hypericum pulchrum, L., var. procumbens Bostrup. — On the Croaghmore scarp. 

 Elsewhere in Ireland known only from the similar scarp of Croaghaun 

 in Achill. In Great Britain found in Shetland only. 

 Rubus. — Only a limited amount of attention was given to the Brambles. R. 

 plicatus and R. rusticanus were frequent. Of some half dozen selected 

 specimens gathered and submitted to Mr. Eogers, the fact that two of 

 them proved to be R. pulcherrimus and three R. iricus may be taken as 

 showing that these two forms, the latter of which appears to be endemic 

 in Ireland, are also frequent. Another interesting gathering was unfor- 

 tunately mixed ; Mr. Eogers writes : — " Stem piece looks like R. Selmeri, 

 while panicle strongly recalls the R. Lettii of Cos. Down and Armagh, 

 and may belong to that."
