8. A. Adidntum-mgrum L. (black S .) ; fronds triangu- 
lar acuminate bi-tripinnate, pinnae triangular the lower pair 
longer than the others, pinnules ovato-lanceolate'inciso-pinna- 
tifid toothed, principal rachis winged, sori at length confluent.

Banks, walls, and fissures of rocks; common. — y. Killarney, 
Co. Kerry; near Tralee, Cork. Jersey. If. 6 — 10. — Stipes 
dark purple as in the preceding species. The most common variety 
is our /3. : a. seems to be merely a more stunted form ; while 
y. is a very luxuriant one, all its parts being drawn out by greater 
heat and moisture. The var. A mentioned by Smith, and by some 
supposed to be our var. y. proves, according to Mr. Moore, to be a 
form of A. Filix-fcemina.

If.. 6 — 9. — It appears that Hudson’s plant, usually referred here, 
was Cystopteris frayilis. Other stations are sometimes given, but 
they, and indeed most of the above, require confirmation, at least as 
to their permanency.
