the following result. Fresh, green shoots, fully three inches 

 in length, were found springing from the Gorse stumps, 

 the Wood Sage {Teucrium Scorodonia) all over the burnt 

 areas had sent up from the old roots shoots six inches in 

 length, while Rubus fruticosus had already developed trailers 

 up to twelve inches long. Ever3^where amongst the charred 

 stumps Gorse seedlings were numerous, the first leaves just 

 showing between the opened cotyledons. 



A week later (September loth), I paid a second visit to 

 the burnt ground in company with Mr. R. A. Phillips, w^hen 

 we added to the renascence flora three species : Galhtm 

 saxatilc, Senecio sylvaticus, and Glechoma hederacea, all of 

 which occured as seedlings. 



In the next month, October, I paid two visits to the hill, 

 one on the ist, the other on the 8th, with the result that the 

 burnt ground flora was further increased by five species, 

 Senecio vulgaris, Sonchus oleraceus, Anagallis arvensis,. 

 Rumex Acetosella and Cardamine hirsuta. The three last 

 of these occurred as seedlings, the two first as w^ell grown, 

 flowering specimens which had gone through all their stages 

 from germination to flow^ering within a bare three months. 



The net result of the observations made in September 

 and October was the discovery on the burnt ground areas 

 of Killiney Hill of a total living flora of eleven species, all 

 of which had made their appearance on this vegetable 

 tabula rasa within a period of three months. The following 

 is a full list of this renascence flora :• — 



Cardamine hirsuta. Glechoma hederacea. 



Ulex europaeus. Teucrium Scorodonia. 



Galium saxatile. Anagallis arvensis. 



Potentilla Tormentilla. Rumex Acetosella. 

 Sonchus oleraceus. • — • — 



Senecio vulgaris. Rubus fruticosus. 



S. sylvaticus. Carex binervis. 



The two species last-named in the above list occurred onl}^ 

 as fresh shoots from old root -stocks ; three others in the 

 list- — Ulex europaeus, Potentilla Tormentilla and Teucrium
