244 The Irish Naturalist. [Sept., 



Ferns were tolerably well represented. The abundance of 

 Lastrea spi7iulosa was remarked. Tlie Scale Fern {Ceterach 

 officinaruvi) grew at Clonbrock, and the great rarity of the 

 Black Spleenwort {Asplenium Adiantuvi-nigriwi) was noticed ; 

 it is equally rare in King's and Queen's Counties, and perhaps 

 it shuns the lyimestone Plain. The Royal Fern {Osvninda 

 regalis) grew in several places ; the Moonwort {Botrychitmi 

 Ltmaria) was gathered sparingly at Killasolan ; and the Adder's 

 Tongue {Ophioglossum mclgatuvi) grew in pastures at Clon- 

 brock. The only Club-moss found was the little Selaginella 

 spinosa, which grew on worked-out bog at Killasolan, and 

 abundantly on the gravel-ridge near Ahascragh. 



The total number of plants noted in the three days I had 

 at Clonbrock was 360, but a number of critical plants were 

 also collected, which have not yet been determined ; these 

 will bring up the list to close on 400 species.

August 6th.— The Club met at the house of Prof. T. Johnson, who ex- 

 hibited a section of Asperococais covipressiis, a brown alga, recently obtained 

 by Miss Hensman and himself by dredging oflf Go Island (Co. Donegal). 

 A. compressiis was dredged by the exhibitor three years ago in Bantry Bay. 

 It is now recorded for the first time as a member of the Irish marine 

 flora ; a southern type of weed, its occurrence so far north is of interest. 



Mr. Greenwood Pim showed sections of the petioles of Nyinphcea 

 alba and A^. marliacea, and drew attention to the curious internal hairs 

 which occur in the air-canals in these and in other aquatic plants. They 

 seemed especially numerous in N. fjiarliacca, a hybrid raised by M. 

 Marliac, and now common in gardens where water-plants are grown.
