MOSSES AND HEPATICS OF KILLARNEY 179 



gathered by Moore on humid rocks, Killarney, and distributed as 

 H. hamtdosum B. & S., to that species, and Dixon (Rev. Bry. 1899, 

 p. 91) also thinks that a barren plant, gathered by Rev. C. H. 

 Binstead in June, 1896, on a rock near Muckross, Killarney, 

 belongs to H. circinale. However, in his notes upon H. circinale 

 in the Handbook (I. c), Dixon expresses a hope that fruit may be 

 found, in order to clear away all doubts of its identity. Mr. 

 Binstead kindly sent me a tuft of the plant already referred to. 

 The presence of a certain lichen among the stems gave us a clue 

 to a probable habitat in another part of the district, where we 

 might find it. On the last day of our visit in August, 1906, we 

 drove to Cromaglown, and in a short time we had the pleasure of 

 finding on rocks a moss in fruit resembling H. cupressiforme L. in 

 habit with denticulate leaves as in the var. mamillatum of that 

 species, but with smaller capsules, not unlike H. molluscum Hedw., 

 as described by Dixon in the Rev. Bry. (I.e.). We suspected it 

 to be either H. circinale or H. canariense Mitt., another critical 

 species requiring fruiting plants to prove its identity. The matter 

 was finally submitted to Mr. Dixon, who declared that our plant 

 was H. circinale Hook. 



Dumortiera hirsuta var. irrigua Wils. In plenty at Tore 

 Cascade in fruit. 



Aneura pinguis (L.) Dum., A. multifida (L.) Dum., and A. 

 sinuata (Dicks.) Limpr., in several places. — A. palmata (Hedw.) 

 Dum. Common on decayed stumps. 



Metzgeria furcata var. fruticulosa (Dicks.) Lindb. On trees at 

 the base of Tore Mt. — M. hamata Lindb. Tore Cascade and 

 other places. 



Eucalyx obovatus (Nees) Breidl. Tore and 0' Sullivan's Cas- 

 cades, in fruit ; frequent. 



Aplozia cordi/olia (Hook.) Dum. Mangerton Mt. 



Acrobolbus Wilsoni (Tayl.) Nees. We saw a fair quantity of 

 this very rare and interesting species on rocks and boulders about 

 Tore, where a few years ago Mr. W. H. Pearson gathered it. It 

 was in young perianth. 



Plagiochila tridenticulata Tayl. Tore Cascade and Mt., 

 O'Sullivan's Cascade. — P. spinulosa var. killarniensis (Pears.) 

 Macv. Tore Glen, very sparingly. — P. punctata var. Oivenii 

 (Steph.) Macv. This plant was named after one of our party, the 

 late Mr. S. J. Owen, of Croesor, by Stephani, who described it as 

 a new species, P. Oivenii. Macvicar, in his Brit. Hep., lately 

 published, has reduced it to a variety of P. punctata, where it 

 undoubtedly belongs. It differs from the type in form of leaf, 

 margin almost entire, and in cell structure. A small tuft was 

 found in Eagle's Nest by Owen in August, 1905. 



Leptoscyphus cuneifolius (Hook.) Mitt. (Clasmatocolea cuneifolia 

 Spruce). It grows rather freely on birch and Frullania on rocks at 

 Cromaglown and Horse's Glen, also Tore Cascade, very sparingly. 



Lophocolea fragrans Moris et De Not. (L. spicata Tayl.) 

 Generally distributed in the glens, mixed with mosses and other 

 hepatics.
