782 SUMMARY OF CURRENT RESEARCHES RELATING TO 



J. J. Marshall* records r he occurrence of Toriula Vahlii at Clee- 



thorpes, in .North Lincolnshire. It occurs on mud dredged from ;i lock. 



It is a Mediterranean moss with a scanty distribution in the south of 

 England. 



Mosses of Haute-Saone.f — A. Coppey continues his phytogeo- 

 graphic studies of the mosses of the Haute-Saone, and treats of the 

 Physcomitrieae, Bryeae, Bartramieas, and Polytricheae. He gives de- 

 scriptions of anew species of Fontinalis and a new variety of Mniobryum. 

 He calls attention to the occasional association of Leptobryum pyriforme 

 with Sphagnum, and suggests that this may explain the frequent intro- 

 duction of the former plant into greenhouses where much Sphagnum is 

 used. 



Hepatics of the Atlantic Islands. J — G. Gola gives a list of forty- 

 two species of hepatics collected by G. Xegri in the Canary Islands in 

 1905. He adds one species (Aneura pinguis) to the recent records 

 published by Bornmuller, Pitard and Corbiere, and Bryhn, and increases 

 the distribution-records of the various islands of the group. 



E. Armitage§ publishes a note upon the presence in Madeira of 

 Frullania germana, a species hitherto known only from the British Isles 

 and Faroes. The Madeira specimens had previously been referred to 

 F. teneriffse. 



North American Sphagnum. II — A. Le Eoy Andrews begins a series 

 of notes on North American Sphagnaceaa. He discusses the grouping 

 of the species within the genus Sphagnum, and adopts Russow's two 

 divisions : (1) Inophhea for the fibrillose-celled group, commonly known 

 as Cymbifolia • and (2) Litophlaa for the rest of the genus. The two 

 groups are distinguished by sundry other characters. For instance, in 

 Inophlcea the cortical cells of the branches are homogeneous, the branch 

 leaves are cucullate, and rough dorsally, and not toothed at apes. He 

 rejects the ten sub-groups adopted by Warnstorf and others for the 

 European species, since he finds them to be not applicable to the exotic 

 species. The sub-groups shade into one another. Yet he would sub- 

 divide Litophhea into Malaco sphagnum for the Rigida sub-group, and 

 Acisphagnum for the Cuspidata. 



North American Hepatics.1T — A. W. Evans publishes a second 

 decade of notes on North American hepaticas. The species concerned 

 are Riccia califomica Aust. s Neesiella pilosa Schiffn., N. rupestris Schiffn.. 

 Metzgeria dichotoma Nees, M.fruticulosa Evans, Scapania spitzbergensis 

 C. Mull., Lopholejeunea atroviridis (Spruce), Ceratolcjeunca integrifolia 

 Evans, Bracltiolejeunea bahamensis Evans, Caudal 'ejeunea Lehmanniana 

 Evans. The most important of these is Neesiella pilosa, the relationships 

 of which are still incompletely understood.
