repens shows great variation ; and Lolium pere7ine (Rye-grass) 

 occurs in several forms from first year to stunted form on waysides, 

 partially naturalised. 



Polypodium Phegopteris (Pale Mountain Polypody) was added 

 to our list of Ferns some twenty years ago, by Wm. Wilson, 

 senr., on one side of Alford, in the Coreen Hills, and by the Rev. 

 A. Milne, shortly afterwards, from the opposite side of Alford. 

 It has continued to spread since it was discovered. It could 

 scarcely have existed here half-a-century ago, as careful investigation 

 was then going on. I have found one plant of Polystichum 

 lobatum (close-leaved Prickly Shield Fern) in the district. Lastrea 

 Oreopteris (Mountain or Lemon-scented Shield Fern) is abundant. 

 Lastrea spinulosa has been found by Mrs. Farquharson. Cystop- 

 teris fragilis (Brittle Shield Fern) ,is still found, as well as 

 Asplenium Ruta-muraria (Wall Rue Spleenwort). While 

 A. Trichomanes (Common Wall Spleenwort) has disappeared from 

 Knockespock Wood it is still found on south side of TowanrierTe 

 on Serpentine rock ; and Mrs. Farquharson has added it to the 

 plants of Alford proper by finding it near Terpersie. A. viride 

 (Green Spleenwort) is found in Auchindoir ; but although not 

 recorded by Dr. Dickie I am almost confident that it had existed 

 there when he published his flora. A. Adiantum-nigram (Black- 

 stalked Spleenwort) occurs with var. Setpentini and an intermediate 

 form. Several forms of Athyrium Filix-foemina (Common Lady 

 Fern) sjrow hereabouts, the most interesting being var. acrocladon^ 

 (Wilson), found by me some years ago, which in some points is 

 different from any of the other forms, and which this season has 

 assumed a peculiar aspect. While Cryptogramme crispa (Rock, 

 Brake, or Parsley Fern) is extinct in one place, I have found it in 

 another in this district. Forked fronds of Blechnum boreale (Hard 

 Fern) are met with. I found a double-leaved and double-spiked 

 plant of Botrychintn Lunaria (Common Moon wort). Our rarest 

 Lycopod is Selagitiella selaginoides (Less Alpine Clubmoss).
