608 SUMMAKY OF" CURRENT RESEARCHES RELATING TO 



mountains, not a proper species, but is a flaccid form of Nardia obovata 

 var. rivularis Schiffn. 59. K. Midler's recently published species Mar- 

 supella ramosa, from Allgau in Bavaria. Schiffner has studied several 

 specimens of this, and gives the results of his examination, being entirely 

 in accord with K. Midler, except as to its affinities. Schiffner holds that 

 it is very closely related, not to M. emarginata and M. Funckii, but to 

 M. Sullivantii in structure of stem, leaves, and other details. 00. He 

 records two hepatics new to Sardinia : Riccia Bischoffii var. ciliifera 

 Lindenb. and R. Gougetiana Mont. 61. Raphidostegium Wdwitschii is 

 recorded from the Dalmatian island of Arbe, where the fruiting plants 

 occur on damp sand among heather. It is an xltlantic moss, which is 

 spreading eastwards along the Mediterranean. 



Ephemeropsis tjibodensis.* — A. Ernst gives an account of Epheme- 

 ropsis tjibodensis Goeb., an extraordinary little epiphytic moss recorded 

 from a mountain in Java. He finds that it is by no means rare, but 

 that it abounds in mountain-woods under favourable conditions, and is 

 widely distributed. He found it on Mt. Salak in Java, in Sumatra and 

 in the Malay Peninsula. He never found it in fruit, but he found plants 

 with gemmse in every stage. He describes the development of these 

 gemmae, and discusses the distribution of the genus. The species grows 

 epiphytically on all sorts of plants, even on mosses and lichens, but 

 prefers rough leaves. 



Cynodontium Jenneri.f — H. N. Dixon discusses the question, What 

 is the true name of Cynodontium laxirete Grebe ? The moss was de- 

 scribed in 18G8 as Didymodon Jenneri by Schimper in an article by 

 C. Howie, and shortly afterwards was referred to Dicranum polycarpum 

 by Wilson. It is now usually regarded as a proper species, and has been 

 redescribed as Cynodontium laxirete by Grebe and as Oncophorus poly- 

 carpoides by Stirton. More recently Stirton has proposed for it the new 

 combination Cynodontium Jenneri, which no doubt is its lawful name. 



Ceratodon conicus.J — W. G. Travis publishes a note on the occur- 

 rence of Ceratodon conicus in the Mersey district. He collected the moss 

 on the sandhills at Formby and at Freshfield, where it grows associated 

 with Bryum pendulum, B. Warneum, etc., just as it does at Dunkirk on 

 the French coast, where it is common in hollows of the dunes. It has 

 also been found on sandhills at New Brighton, Cheshire. 



What is Dicranoweisia robusta Vent. ? § — A. Luisier discusses the 

 identity of Dicranoweisia robusta Vent., a Portuguese moss, collected by 

 E. Sequeira at Penafiel, and described by him under Dicranodontium in 

 18<si, and by Venturi under Dicranoweisia in 1882. And since then it 

 has remained an unknown species, at least outside Portugal. Recently 

 Luisier found among some of I. Newton's specimens at the Polytechnic 

 Academy at Oporto two specimens of Glyphomitrium polyphyllum, which 

 also bear the name Dicranoweisia robusta Venturi, and which had been
