Law. The latter are small and neat. (I have the same from 

 Ruberslaw, R.) 



12. Cystea FRAGiLis=Cystopterisfragilis. Uncommon. B. It 

 ornaments the Lady's Bridge in the grounds of Milne-Graden ; and 

 abounds on the face of the rocks at Stitchell Linn. ]\Ir. Carr says 

 it is also found in the caves below St. Abb's Head. 



13. AspLENiuM SEPTENTRiONALE. N. In the fissurcs of the 

 columnar cliffs of Kyloe crags, where it was first noticed by the Rev. 

 J. Baird. (R. Minto crags. Stat. Ace. Roxburghs. p. 361.) 



14. A. ALTERNiFOLiuM = A. germanicum . Bell in Trans. Bot. 

 Soc. Ediu. i. 119. Tate in Trans. Berw. N. Club, iii. 102.— 

 Mr. Dickson found this rare species " on some sunny rocks, about 

 two miles from Kelso, on the Tweed ;" but the locality has eluded 

 all subsequent research. N. On Kyloe crags, G. R. Tate. 



15. A. RUTA-MURARiA. lu fissurcs of rocks, and on old walls 

 and ruins. B. On the ramparts of Berwick in front of Wellington 

 Place, Dr. P. W. Maclagan. Abundant in the cre^-ices of rocks 

 near the Rammell Cove, and between it and Fast-Castle, J. Hardy. 

 On sandstone rocks by the Tweed below Ladykirk house, F. Douglas. 

 — R. On Melrose Abbey. — N. On Kyloe and Spindlestone crags. 



16. A. TRiCHOMANES. lu crcvices of rocks in deans, on basaltic 

 crags, and on rmns, frequent. 



17. A. MARiNtfM. Of frequent occurrence on the coast of 

 Berwickshire, commencing on the cliffs above the Sandy-beds and 

 the Pigeon's Cove, and recurring at intervals even unto the Cove- 

 shore. It is of small size when the cliffs are abrupt and exposed to 

 the sea blasts, but in the shelter of the Coves it grows luxuriantly, 

 and the fronds attain a length of 12 or 18 inches. Mr. Hardy sent 

 me the finest specimens I have ever seen from the Rammel Cove. 

 The fern also grows on sandstone rocks by the Tweed below Ladykirk 

 house, — a station which is about seven miles distant from the sea. 



18. A. ADiANTUM-NiGRUM. In the fissures of rocks in deans, on 

 stony wooded braes, on our sea-banks, and sometimes on ruins. 

 Perhaps the stations where it grows most abundantly are the wooded 

 crags above Belford, and in the dean above Akeld. 



19. A. FiLix-FCEMiNA = Aspidium filix-foemina = Athyrium filix- 

 foemina. The Lady- Fern . On grassy banks in deans with a northern 

 exposure, and in shaded woods, frequent. 



20. ScoLOPENDRiuM vuLGARE = Aspleuium scolopendrium, 

 Lightf. Fl. Scot. 660. — Hart's-Tongue. — B. In the Pigeon's Cove 

 near the Needle-eye, Thompson ; in a cove between Fast- Castle and 

 Redheugh ; on rocks by the Pease Bridge, and on the wall of the 

 road above the bridge ; and m Dunglass-dean. I find it sparingly 

 in several other locahties, all, I think, on the east of our district. 

 The fern has a great tendency to become monstrous. See Trevelyan 

 in Trans. Bot. Soc. Edin. i. p. 56. The summit of the frond is 

 often dilated and divided into two or three segments ; sometimes it 

 is deeply divided into two of equal size ; and sometimes two distinct
