10. D. squarrosum, Schrader. Leaves from a broad sheath- 

 ing base lanceolate, obtuse, squarrose, crisped when drj'; cap- 

 sule ovate, subcernuous; lid rostrate. Schrad. Journal, 1802. 

 Muse. Brit. ed. 2, p. 98, t. 17. 



On wet sandy spots on the banks of rivers : rather rare. 



11. D. pel/usidum, Svvartz. Leaves lanceolate, their mar- 

 gins slightly undulate, serrated, rather obtuse ; capsule ovate, 

 subcernuous; lid rostrate. Swartz. Muse. Suec. p. 35. Muse. 

 Brit. ed. 2, p. 99, t. 17. 



On wet sides of streams. Mr. Templeton's specimens of D. virens 

 of Mr. Turner's Muse. Hib. prove to be D.pellucidum. He pointed 

 it out to me in its locality at Lame, which being nearly on a level with 

 the sea, could scarcely be expected to produce an alpine species. Nor 

 did I meet D. virens in the late Dr. Scott's collection. I suppose, for 

 the present, it is better omitted from the Irish catalogue. 



12. D. crispum, Hedw. Stems short; leaves from a sheath- 

 ing base setaceous, somewhat distichous, flexuose and recurved, 

 crisped when dry; capsule ovate, erect; lid with a long beak. 

 Hedw. St. Cr. v. 2, t. 33. Muse. Brit. ed. 2, p. 99, t. 17. 



On dry banks : near Belfast, Mr. Templeton ; near Killarney, Mr. 

 W. Wilson. The stems and leaves have a light pea-green colour. It 

 appears to be rather rare in Ireland. 



13. D. Scottianum, Turner. Stems caespitose ; leaves erecto- 

 patent subulate, their tops scarcely subserrulate, crisped when 

 dry ; capsule ovato-cylindraceous, nearly erect ; teeth of the 

 peristome nearly entire ; lid with a long beak. Turn. Muse. 

 Hib. t. 6,/. 1. Muse. Brit. ed. 2, p. 100, t. 18. D. flagellar e

On stones in woods, and on dry banks : wood at Blackwater bridge, 

 County of Kerry : banks of Looscaunuch Lake, County of Kerry. 

 Pedicells waved. In the same tuft some stems have the leaves sub- 

 secund, others directed in all ways. The peristome is most remarkable, 

 and keeps it distinct from every other known species. The teeth are 

 short, marked down the middle by a longitudinal dark line, they are 

 rarely perforate, and still more rarely split, and then only at the very 

 summit. It may thus be easily known from D. fiagellare Hedw. 

 besides by the want of "flagelliform" branches, by the more erect cap- 

 sule whose mouth too is narrower, by the crispation of the leaves when 

 dry, and by the shorter pedicells as well as the general smaller size of 

 the plant. 



14. D. flagellare, Hedw. Elongations of the stems flagelli- 

 form ; leaves of the stem subulate, serrulate, falcate ; of the 

 elongations shorter adpressed ; capsule subcylindraceous sub- 

 cernuous ; lid with a long beak. Hedw. St. cr. v. 3, t. 1. Weber 

 et Mohr. Bot. Tasch.p. 173. Wahl. Fl. Lapp. p. 337. 



In the wood at Glenflesk, County of Kerry : very rare. I have 

 seen no other British specimens than from the locality quoted. It is 

 more likely to be confounded with D. scoparium than with the pre- 

 ceding ; but may be known by the flagelliform shoots, by the more
