27. T. Ifihermca (^^itten), in ^eemeLim^ B ''Joiirnal of Botany," vol. 
v., p. 329, 1867. Eraithwaite, in ditto, vol. ix,, p. 294, tab. 
120, f. 5, 1871. Anoectangium Hornschuchianum, Bryol. Brit., 
p. 294. Trichostomum, cirrhifolium, Schimp., MS. Didymodon

Hab. Eocks in mountainous parts of the country. Dr. Taylor first 
recognised this moss about Killarney and Dunkerron, and 
mistook it for Anoectangium Hornschuchianum of Hoppe. 
In 1861 I had the pleasure of pointing it out to Dr. Schimper 
and Mr. Wilson, at Killarney ; and in the following year I 
observed it growing on Brandon mountain, Kerry. It has 
never yet been seen in fruit, so that its place in the genus 
Tortula is only provisional. 
28. T. smuosa (Wihon), MS. Mitten, in Seemann's ''Journal 
of Botany," vol. v., p. 327, 1867. Dicranella sinuosa, Wils. 
Eraithwaite, in Seemann's '' Journal of Bot.," vol. ix., p. 294, 
tab. 120, f. 6, 1871. 
Hab. On limestone rocks and also on roots of trees. The Phoenix 
Park, D. Orr. Between Portmarnock and Malahide. The plant 
here referred to, T. sinuosa, has, like the last species, only been 
found in a barren state, and may belong to a different genus. 
It bears a close resemblance to Weissia tenuirostris, of Hooker 
and Taylor. 
29. T. fragilis (Hook.). Didymodon fragilis, Hook., in Drummond, 
Muse. Amer., 1828. Tortula fragilis, Wils. ^6?^ Eraithwaite, 
in Seemann's ''Journal of Bot.," vol. v., p. 295, 1871. 
Lindberg, Europ. Trichost., p. 46. Barbula fragilis, De !N'otr., 
Muse. Ital., 1, p. 68, tab. 35. Bryol, Europ., vol. vi., suppl. 
1, tab. 639. 
Hab. On rocks and stones. N"ear Koundstone, Connemara. Barren 
specimens of this moss were collected by me in 1861, and 
sent to Mr. Wilson, who could not then decide what it 
was ; but our plant has since been identified, and proves to be 
the true species. 
30. T. squarrosa (De TTotr.). Syllab., p. 180, et Muscol. Ital. 1, 
p. 61, tab. 31. Bryol. Brit., p. 126, tab. 43. Eridel, Bryol. Tniv.

Europ., 1^0. 457. Pleurochsete squarrosa, Lindberg, Europ. 
Trichost., p. 47. 
Hab. On limestone rocks and sand-hills. Sands at Portmarnock, 
Dr. Taylor. Between Malahide and Portmarnock, Dublin; 
Arklow, Wicklow. 'Not hitherto observed elsewhere in 
Ireland.
