170 The Irish Naturalist. October, 



I have thought it well to define exactly the stations of these three plants 

 (owing to their cliffy habitat, they are in no clanger of extermination as a 

 consequence !) because from the time of Templeton there has been a 

 looseness in the use of the local place-names, and as a result considerable 

 uncertainty as to the location of the stations. 



■Mr. Lilly kindly took me to see his Magilligan station for Lastrea Thely- 

 pteris. It lies south of ^Magilligan camp — a long narrow^ marshy meadow 

 adjoining (on the east side) the main road to Bellarena just two miles 

 from Magilligan Point. There is plenty of the ]Marsh Fern here, growing 

 dwarf among a vegetation consisting largely of Poteniilla palustris and 

 Galium paliistre, along with Menyanthes, Caltha, Spiraea, Iris, IMentha, &c. 

 The plant appears to be now almost extinct in Ulster through drainage, 

 and this Derry station is very welcome.

Muscineae of Achill Island. 



In August, 191 1, a party consisting of Messrs. J. C. Wilson, J. B. Duncan, 

 D. A. Jones, and the late S. J. Owen visited Achill Island in search of 

 Cryptogams, and Mr. Jones gives an interesting account of what was 

 done, with a full list of the species collected, in the Journal of Botany 

 for September. They were successful in the principal object of the 

 expedition in finding again Adelanthus dugortiensis, a small quantity of 

 which mixed with mosses Canon Lett gathered in 1903 during a fog 

 on Slievemore. They found it in single stems in hummocks of other 

 mosses and also in pure tufts on rocky ledges. It is endemic, and is 

 allied to A. unciformis of South America. The fruit is not known. It 

 is satisfactory to know something about the habitat of this curious species, 

 the most interesting liverwort which has been found in the British Isles 

 of late years. Scapania nimhosa, hitherto only known in Ireland from 

 Brandon, was also met with on Slievemore, but sparingly as single stems 

 growing with mosses. Mr. Jones found it also in Carnarvonshire 

 on Glyder Fawr. The north-west slope of Slievemore is a paradise of 

 Hepaticae ; mosses are not so abundant there as this paper shows, but 

 there are fine tussocks of the rare Dicraniim uncinatum. 



The following are marked as additions to the Irish list, but it should 

 be pointed out that many of these records have been already incorporated 

 in Lett's " Musci and Hepaticae " of the Clare Island Survey [Proc. 

 R. I. Acad. 1912) and " Census Report " (1915), and also in the " Census 

 Catalogue of British Hepaticae " (2nd edition, 1913) : — 



Weisia curvirostris var. comniutata, Aneura major, Marsitpella Pearsoni, 

 Eucalyx ohovata var. rividaris, Lophozia badensis, Sphenolobus Pearsoni, 

 and 5. exsectiis. Hypnum Patientiae should not be included in this list 

 of additions as it is widely spread throughout the counties of Ireland, 

 though nowhere common. Mr. Jones has followed Canon Lett in placing 

 Moerckia Flotoiviana among the additions to our list, but it was previously 

 found at Malahide and in several other county divisions. No indication 

 is given in the paper of species which are additions to W. Mayo,
