Asplenium Adiantum-nigrwn, L , var. acutum, Poll. Hedge- 

 banks, Newtonards, Co. Down, Dec, 1892. — J. L. Praeger. Not 

 so "produced" at the leaf-apex as some of the Irish specimens — 

 A. B. 



Ceterach officinarum, Willd., b. crenatum, Milde. Near Bally- 

 vaughan, Co. Clare, May, 1892. — H. L. Levinge. Scarcely this 

 var., the dentation is so slight, and in many of the pinnae so like 

 a mere inflexion of the margin, that I should hesitate to put the 

 varietal name to it. — A. B. 



Polystichmi angulare, Presl., var. subtripinnaiimi, Moore ? — 

 Tremadoc, S. Carnarvon, Sept., 1891. — J. L. Williams. I do 

 not know Moore's var. so called. — A. B. 



Equisetum variegatum, Schleich., c. WiUoiii, Newm. Edge of 

 Lough Drin, Co. Westmeath, April, 1892. — H. L. Levinge. 

 These specimens have the stems not above half the thickness of 

 the Killarney plant ( Wilsom), and are altogether a much slenderer 

 plant. I should have named them E. variegatum, var. majus, 

 Syme, that is the same as the Poyal Canal plant at Dublin, 

 &c.— A. B.

 Lough Neagh, July, 1892. — R. L. Praeger. Correct. — A. B.
