482 SUMMARY OF CURRENT RESEARCHES RELATING TO 



and Co. Armagh. He also withdraws the record of Archidium alterni- 

 folium in Co. Down as incorrect. The plant, always sterile, is now 

 suspected to be a form of some species of Dicranella. 



French Mosses.* — A. Coppey has written an account of the 

 MuscineaB of Nancy, hitherto but little known. He corrects Godron's 

 list of 1843, and adds a supplement of 103 mosses, seven sphagna, and 

 twenty-three hepatics. He also adds much information about bryological 

 study and local exploration. 



Moss-flora of JMorway. — J. Hagen t begins a series of 'monographs 

 upon the moss-flora of Norway with an account of the Orthotrichacea?, 

 viz., Zygodon, Ulota, Orthotrichum, Stromia, and Aulacomitrium. 

 Stromia is a new genus created for the reception of Orthotrichum 

 obtusifolium and 0. gymnostomum on account of their peculiar leaf- 

 shape. Glyphomitrium Daviesii is transferred by the author to the 

 exotic genus A ulacomitrium. The geographical distribution of the species 

 is carefully worked out. 



The same author % gives an account of the moss-herbarium of the 

 late E. Ryan (born 1S49, died 1905), treating the records therein 

 contained on the lines of geographical distribution. Thus the paper 

 consists of a series of little moss-floras for eleven Norwegian counties or 

 administrative areas. 



Bryology of Tornean Lapland. — H. N. Dixon gives an account of 

 a visit with W. E. Nicholson to Abisko in Tornean Lapland in August 

 1907. He describes the physical geography of the district, and divides 

 it into three regions : upland, birch-wood bogs, river ravines. The river 

 ravines provide the best collecting ground. An annotated list of 21G 

 mosses and 47 hepatics is given. In a long note the relationship of 

 Mnium hymenophyllum and 31. hymenophylloides is discussed. The 

 author is convinced that M. hymenophylloides is a variety at most, in 

 fact not much more than a rupestral form of M. hymenophyllum, being 

 a form modified by growing in rock-crevices. The reasons for this view- 

 are fully stated. M. hymenophylloides is the older name. The species 

 appears distinct from Cinclidium. But the fruit has not yet been found. 



Bryophytes of the Algau Alps.|| — L. Loeske publishes a critical 

 study of the bryophytes of the Algau Alps. Among his most important 

 results are : 1. The new genus Barbilophozia. 2. Discussion of the causes 

 of dark coloration of some species. 3. The influence of illumination. 

 4. Critical examination of Pohlia. 5. Critical examination of Philonotis. 

 6. Systematic arrangement of the Brachythecieas into Eustegiaceaa and 

 Brachystegiaceaa. 7. Synonymy of Brachythecium densum. 8. On 

 Hypnum molluscum var. robustum. 9. Changes of nomenclature. 10. 

 Critical study of Thuidium hystricosum, 11. On Neesiella rupestris. 

 12. New forms or species.
