belonging to rheticum?) I can see only varieties, variations, 
aberrations. 
Athyrium (Filia femina) ovatum, Newm. Phytol. 
Province - 12. Keswick, Cumberland. Extinct there? 
Syn. 1894. Cyb. iii, 2783—4. Phytol. iv. 369 & 646. The 
variety latifoliwm of Babington and other describers. 
Phegopteris plumosa, J. Smith. 
Province - 10. Yorkshire, a single plant ? 
Syn. 1894. A curious aberration of Filia famina, at first sight 
suggesting the subgenus Allantodea, rather than Athyrium. 
Asplenium fontanum, Presl. 
Provinces - 2 8---78-101112--15. 
Ambiguity. Alien or Errors? Cyb. iii. 275 & 520. Reported 
from the counties of Dorset, Hauts, Kent, Surrey, Bucks, Merio- 
neth, Derby, York, Northumberland, Westmoreland, Cumberland, 
and Kincardine. All or nearly all these dozen counties become 
inadmissible when critically inquired into. In addition to the 
references given in the Cybele Britannica, two other locality- 
claims have been put forth in the Manual of British Botany, 
namely “ Ashford, Hants,” and “Northumberland.” Does the 
former of these intend the locality of or near “‘ Ashfield Lodge,” as 
reported in the Phytologist for 1852, with Mr. W. H. Hawker's 
testimony to the fern being “truly a native of the locality”? If 
so, its nativity there is ill sustained by the following extract from 
a letter written by a celebrated Pteridologist, in November, 1853 ; 
namely, ‘A correspondence with the Rev. W. Hawker fixes the 
Hants habitat of fontanum on ‘the inside wall of a garden,’” The 
wide habitat of “‘ Northumberland ” is not accepted by the Authors 
of the New Flora of Northumberland and Durham, dated in 1868. 
It is to be feared that “ Asplenium fontanum” ought still to go to 
the category of errors. 
Asplenium (Trichomanes) anceps, Lowe. 
Provinces -- 38-15. And very likely in others between. 
Syn. 1896. Cyb. iii. 277. This is a large state, rather than 
a distinctly different variety of Trichomanes. As found on the 
hedgebanks, in some of the lanes in South-west Surrey, it closely 
resembles the anceps of Madeira and the Azore Isles. 
Asplenium (Adiantum nigrum) productum, Lowe. 
Provinces--3-%? Surrey! Stratford-on-Avon ? 
Syn. 1899. A very elongate form of the species, but traceable 
through transition links into the more usual form. I have not 
seen English examples so slenderly divided as the acutum of 
Treland, figured in Newman’s History. My longest English 
example measures about twenty inches, stipes all included; its 
lowest pinna exceeding four inches; all the pinne being much
