360 HEPATIC^ OF LOUGHBRAY, CO. WICKLOW. 



Plagiochila asplenioides Dumort. Plentiful on damp banks. — 

 P.spinuhsa Dumort. Plentiful in woods and on damp banks. 



Mylia Taylori B. Gray. On damp ground, in large patches. 

 — M. anomala B. Gray. Considered by many hepaticists a 

 doubtful species, and closely allied to the former. Dr. Carrington 

 states the cells are of a different form from tbose in M. Taylori, and 

 contain fusciform corpuscles, and we have observed, amongst other 

 differences, that it wants the papillose character of the outer cell- 

 wall, so obvious in M. Taylori. Hab. Amongst Sphagnum, D. McA. 

 & F. W. M., 1889. We have gathered the same plant on Brandon 

 Mountain, Kerry, in 1881. 



Jungermania crenulata Sm. Abundant by the roadside, D. McA. 

 & B,. W. S., 1889. — Var. gracillima Hook. Abundant ; often mixed 

 with the preceding. Dr. Moore states that at Westaston, Co. 

 Wicklow, this variety is abundant, and none of the true crenulata 

 grows with it. — J. pumila With. In the crevices of damp rocks 

 near streams, Dr. Moore. — J. spharocarpa Hook. Abundant on wet 

 rocks and on the margin of the lake, on the damp bank among 

 stones. — J. riparia Tayl. — J. nana Nees. Stems csespitose, from a 

 quarter to half an inch high ; innovations arising below the apex, 

 slender, terete ; cells large, pellucid, those of the margin somewhat 

 larger ; perianth obtuse, plicate, quadrangular ; mouth fuur-toothed, 

 capsule globose. On wet banks near streams ; apparently a rare 

 plant in Ireland, and closely allied to J. crenulata and gracillima. — 

 J. Dicksoni Hook. On rocks and moist banks, very rare ; single 

 stems only (Dr. Moore). The re-discovery of this plant in this or 

 any other locality would be interesting. — J. minuta Crantz. Damp 

 peaty banks ; also found creeping over the naked moist rocks in 

 shady places. Plentiful in fruit, in which state it is rarely found. 

 D. McA. & R. W. S., 1889. — J. exsecta Schmidel. Damp banks ; 

 rare. D. McA., 1889 (<?). Easily known from all others by the 

 distichous leaves, furnished above the middle of the upper margin 

 with a strong sharp tooth, which points obliquely to the apex. — 

 J. intermedia Lindenb. On damp banks between rocks, D. McA., 

 1887. — J. vent ricosa Dicks. Plentiful on damp banks. — J. bicrenata 

 Lindenb. On damp shaded banks. — J. incisa Schrad. On damp 

 turfy banks ; rare. — J. porphyroleuca Nees. On decaying wood ; 

 rare. D. McA., 1889. — J. infiata Huds. On wet rocks and in 

 boggy places; abundant near the summit of Kippure Mountain, 

 bearing colesule. D. McA., September, 1880. 



Nardia emarginata B. Gray. Abundant on wet rocks. — X. 

 sphacelata Carrington. On moist rocks ; rare. Often mixed with 

 the preceding. Dr. Moore, 1869, fide Lindberg, S. 0. L. 1873. 

 F. W. Moore, 16th July, 1887; plentiful. D. McA. & R, W. S., 

 1889 (fruit). — X scalaris S. F. Gray. Abundant on moist banks 

 and on wet rocks. — Var. rivularis Lindberg. Plentiful on wet rocks. 

 — Var. robusta Lindberg. A very variable plant ; easily known 

 from N. hyalina and X. obovata by the white rootlets. — A 7 , compressa 

 B. Gray. Abundant on wet rocks where the water is more or 

 less trickling over it, and is often submerged. — Var. rigida Lindberg. 

 This form comes near to N, sphacelata. Stems shorter, narrower,
