Lastrea rigida in Ireland. 



The President exhibited a specimen of Lastrea rigida which had 

 been kindly transmitted to him by Mr. C. L. Darby, of Thomastown, 

 accompanied by the following information : — 



" I gathered this fern early in the present month (September), in 

 the county Louth, at Townley Hall, the residence of Mr. Balfour, It 

 was growing on a wall built of clay-slate, and much overhung with 

 trees. I saw about thirty plants of it ; and the following ferns were 

 also growing in company : — Ceterach officinarura, Asplenium Ruta- 

 muraria, A. Trichomanes, Athyrium Filix-foemina, Lastrea Filix-mas, 

 and Scolopendrium vulgare. This is an interesting extension of 

 geographical range." 



Drawings of British Plants. 



The President exhibited a volume of drawings of British plants, 

 executed in the most beautiful manner. The volume was only one 

 of nine, which he was desirous of disposing of; and he would be 

 happy to show it to any botanist who might call for that purpose, or 

 correspond with any one disposed to purchase. He considered it 

 impossible for the drawings to be surpassed in beauty or accuracy ; 

 and the collection was almost perfect. The drawings were arranged 

 according to the natural system ; and in the volume now on the table, 

 and extending to the Caryophyllaceaj, Helianthemum Breweii of 

 Planchon was the only species omitted. 



Spirant hes cernua in Ireland. 



The President read the following note, from Mr. D. Moore, of Glas- 

 nevin : — 



" I have not heard that Spiranthes cernua has been seen in its Irish 

 habitat for several years. The last information was from Dr. Arm- 

 strong, who told me the ground where it grew had been ploughed up 

 and sown with oats. Sic transit, &c." 



The President also made a viva voce communication on Urcdo Fru- 

 menti, the fungus-blight of wheat (see p. 700).
