58 SUMMARY OF CURRENT RESEARCHES RELATING TO 



metres), the forest region (1000 to 1800 metres), the sub-alpine (above 

 1800 metres). Finally, he discusses the origin of some of the Medi- 

 terranean species, especially the new endemic Mielichhoferia Coppeyi, a 

 representative of an exotic genus mostly of southern distribution. 



Moss-flora of Portugal.* — A. Luisier publishes a preliminary list of 

 Portuguese mosses — thirty-three species collected in the neighbourhood 

 of S. Fiel and Lisbon. He has in hand much more material waiting to 

 be worked out. 



Moss-flora of Madeira.f — A. Luisier gives a list of the Bryophytes 

 of Madeira — seventeen hepatics and eighty-one mosses, including three 

 new varieties. Three genera and eight species and varieties are added 

 to the Madeiran flora. 



Mosses of Italian East Africa.:}: — L. Micheletti gives an enumera- 

 tion of eighteen species of mosses collected by A. Rolli and M. Da 

 Carbonara in the Italian colony of Eritrea, Among them are the names 

 of ten new species determined by Y. F. Brotherus, but without diagnoses. 



Bryophyta of Ruwenzori. — (1. Negri § gives an account of the 

 mosses collected on Mount Ruwenzori during the Duke of the Abruzzi's 

 expedition. The total number of species recorded from Ruwenzori is 

 62 ; 38 of these were collected by the expedition, among them being 28 

 new species and 2 new varieties. G. Gola || enumerates the number of 

 hepaticas recorded from Ruwenzori — namely, 50 species. The Duke of 

 the Abruzzi's expedition collected 33 species, 1(5 of which are new to 

 science. 



North American Species of Amblystegium. — A. J. Grouty pub- 

 lishes some notes on Amblystegium, the North American species of which 

 he has lately studied with great care. He found the European experts 

 to be at variance over such difficult species as .4. hygrophilum, A. 

 radicate, A. orthocladon, A. Kochii. He maintains that the minute eco- 

 state species ought to be removed to the Hypnea'. The remaining 

 uuicostate species can then be divided into four groups : 1. Euambly- 

 stegium, with live species {A. serpens, A. Juratzkanum, A. Kochii, 

 A. compaction, A. Holzingeri). 2. Sygroamblystegium, with six species 

 (.4. varium, A. Jiuviatile, A. irriguum, A. orthocladon, A. iwterophilum, 

 A. filicinum). 3. Leptodictyum, with six species (A. riparium, A. 

 brachyphyllum, A. brevipes, A. laxirete, A. vacillans, A.Jtoridanum). 4. 

 A. Lescurii (transferred to Sciaromnium, by Brotherus). Each of these 

 four groups is critically discussed. A new species and a new variety are 

 described. E.J. Hill** gives an account of the habitats and plant- 

 associations of Amblystegium noterophilum, a cold-water species which 

 he has found in fruit.
