Mosses of the Atlantic Islands.* — H. N. Dixon publishes notes on 

 two collections of mosses gathered in the Atlantic Islands, the one in 

 Madeira by E. Arrnitage, the other in the Azores by G. C. Druce. 

 1. The Madeira collection comprised some 180 specimens in 76 species, 

 and included 18 additions to the moss-flora of the island and three to the 

 flora of the Atlantic Islands. One of the latter three is Dicranella hetero- 

 malla, male plants with the interesting character of axillary bulbils. 

 To Grimmia trichophylla should be referred as varieties or subspecies the 

 following : G. Lisse, G. canarimsis, G. subsguarrosa, G. Stirtoni, and 

 G. azorka. Brachymenium Philnotula appears indistinguishable from 

 the East African type. 2. The Azores collection, though small (13 speci- 

 mens), included a new species, Bryum clavatulum. 



Synonymy of European and North American Mosses, f — N. C. 

 Kindberg publishes notes on the synonymy of European and North 

 American Bryinese, being a list obtained by collating the nomenclature 

 employed in his own European and North American Bryineas with that 

 in V. F. Brotherus' Bryales in Engler and Prantl's Die naturlichen 

 Pflanzenf amilien . 



North American Mosses. J — C. C. Plitt gives an account of the 

 methods of asexual reproduction observed by various authors in Leuco- 

 bryum glaucum, viz. the formation of rhizoids on ordinary or on peri- 

 chsetial leaves, or the formation of leaves readily breakable from the 

 parent stem. 



I. Hagen exposes? a blunder in nomenclature by which the binomial 

 Elmtera orniihopodioides was set up by S. C. Stuntz in place of Neekera 

 complanata in 11)00. 



E. G. Britton || publishes some notes on C. G. Pringle's Mexican 

 mosses. 



Mosses of Mexico.^ — J- Cardot continues to publish his preliminary 

 diagnoses of Mexican mosses. The third instalment contains thirty-three 

 new species and varieties, mostly belonging to the orders Grirniniacese 

 and Bryacea?.
