Bellbank,” he writes, “I found a root under a dripping rock." Bolton’s 
figure certainly represents this plant. Mr. Babington also states that 
he has a specimen from the same place, exactly like Bolton's figure. 
There seems to be no question therefore, that it once grew there, 
though it has not as far as we know been gathered in this habitat 
during the present century. Its present stations within the limits of 
the United Kingdom, are confined to the south-west of Ireland, 
where, in the rocky glens, caves, and ravines of the counties of Cork, 
and Kerry, it is met with not unfrequently, and sometimes in a 
most luxuriant condition. We learn from Dr. Kinahan* that the 
Trichomanes flourishes in a district extending from about 51° 30° N. 
to 52° 40° N., Bantry being the most southern recorded station, and 
the Cumailte Mountains the most northern; and as far east as about 
7° 50° W. in the Blackwater Valley. The plant grows in the greatest 
perfection, that is, fruits most regularly and perfectly at Inveragh, 
and in the valley of the Blackwater; the extreme humidity of the 
Killarney district, whilst encouraging the ordinary growth of the 
plant, interfering with its fruiting. Outside this well marked district 
Dr. Kinahan observes, are two outlying stations at which it is now 
probably extinct, namely Wicklow in about 52? 10’ N. and 6°20 W., 
and Bellbank, near Bingley, Yorkshire, in about 53? 30° N. and 
1? 55 W. On Turk Mountain, Killarnoy, one of the most celebrated 
stations, it ascends to an altitude of 1500 feet. The rapacity of collec- 
tors has thinned if not eradicated it in many localities, so that it be- 
comes desirable not to point out too exactly the habitats which are 
known. We therefore merely indicate a few recorded stations:— 
Humber.—Yorkshire : formerly found at Bellbank, near Bingley. 
Leinster.— Wicklow: Hermitage Glen, Dr. Mackay; Powers- 
court Waterfall, Dr. Stokes. j 
Munster.—Cork : Glendine near Youghal, R. Ball; Glenbour, 
Killeagh, near Youghal, J. A. Fisher ; Temple Michael Glen near 
Cork, D. Murray; Ballinhasy Glen, near Cork; Bandon, S. P. 
Woodward ; Fall of the Clashgariffe, J. Drummond ; near Glandore, 
Dr. Allman ; near Bantry, C. C. Babington; near the summit of 
Carrigeena, Kildorrery (elev. 1000—1200 feet), J. Carrol. Water-
