 Cogn. Hepat. Bclg., p. 36. 

 Hab. Wet banks among mosses, and bogs among Sphagnum. Eatber 

 common in many parts of Ireland, but more abundant in the 

 southern and western counties. 



Tar. a. conferta minor. On rotten wood frequent, Carrington. 



Var. yS. spliagnorum, Hook. Brit. Jung., t. 15, 3. !More or less fre- 

 quent among Sphagnum in many of the bogs through Ireland, 

 but never in much quantity together. 



■8. Cephalozia catenulata (Hlibener), Lindb. Stem ascending, flexuose, 

 rigid. Leaves ovate, concave, acutely bifid, adpressed. Involucral 

 bracts bi-tri-fid. Colesule cylindi-ically trigonous, minutely 

 toothed at the apex.

Hab. On shady damp banks, and in woods. Yeiy common in the Kil- 

 lamey and Cromagloun woods ; also about Brandon Mountain 

 as well as elsewhere in Co. Kerry ; about Kylemore, Co. Galway ; 

 Lackan bay, Co. Mayo ; Gleniif, Co. Leitrim ; Lough Bray, Co. 

 Wicklow. 



This pretty little plant is rather puzzling at times to distinguish from 

 certain states of other species of the genus. It bears a greater 

 resemblance to young forms of C. connivens than to any other. 

 Dr. Carrington, Avho has paid great attention to it, and figured it 

 (Trans. Bot. Soc. 'EAmh.l.c), considers Taylor's J. reclusa identical 

 with Hiibener's C. catenulata, as also does Dr. Lindberg, who has 

 had such excellent opportunities for compaiing the Irish plant 

 with foreign specimens of C. catenulata. Dumortier, however, 

 holds that they are distinct species, and describes them as such 

 (Hepat. Europ., p. 92 (1874)). Dr. Spruce, another excellent 

 observer, agrees with Dumortier, and describes J. reclusa, Taylor 

 (see his Muse, et Hepat. Pyren., in Trans. Bot. Soc. Edinb., m. 

 p. 208, as a distinct species). 



■9. Cephalozia Turneri (Hook.), Lindb. Stems creeping, branched. 

 Leaves incumbent, acutely bipartite, segments conduplicate, spi- 

 nidose-dentate. Colesule terminal, contracted and slightly dentate 

 at the mouth.
