El. Hib., p. 26. The late Mr. James Drummond is men- 
tioned as the discoverer of this plant near Cork, but no authentic 
Irish specimens of it are known to be in any herbarium, and it 
is now supposed that a variety of T. fallax was mistaken 
for it. The late Mr. Wilson, in his " Eryologia Britannica, " 
expressed some doubt whether the genuine Barbula gracilis of 
Schwaegr. (Suppl. 1, p. 125, tab. 34; De I^otr,, Muse. Ital., 1, 
p. 57, tab. 28), had been found in Britain or Ireland. The 
species therefore is placed at the end of our list, as being 
a very doubtful native.]

Calyptra large, cylindrical, campanulate, apex attenuate-rostrate. 
Capsule long pedicellate, erect, oblong, or oblong- cylindrical,

i Hab. On limestone, or mortared walls. Very large and fine on 
the tops of walls by the side of the public road leading from 
the town of Galway to Ahascragh. Also about Killarney. 
Cork, Dr. Power, in EL, Cork; and in many other parts of the 
country ; but never yet, I believe, found fruiting in Ireland.
