A. Prescott * gives a short account of the boulder-fern, Dicksonia 

 pilosiuscula. 



Ferns of Temperate South America.f — 0. Christensen gives an 

 account of a collection of ferns made by C. Skottsberg in temperate 

 South America, namely, in the Falkland Islands, Tierra del Fuego, West 

 and East Patagonia, Chiloe, Juan Fernandez. In all he enumerates 67 

 species. Additions to the flora of Juan Fernandez and of the Falklands 

 are recorded ; and three new species are described, namely, Polypodium 

 (Grammitis) patagonicum, HymenophyUum Skottsbergii, and the curious 

 Bhchnum longirauda, which previously had been confused with the 

 Malayan Asplenium longissimum 131. ; the proliferous fronds may be two 

 metres long, and hitherto have been found in the sterile state only. Van 

 den Bosch's genus Serpyllopsis is revised for the species Trichomanes 

 csesptiosum, which is intermediate between HymenophyUum and Tricho- 

 manes in some respects, but is distinguished from both by the indeter- 

 minate growth of its fronds and the red pubescence of the rachis and 

 midribs. 



Ferns of Argentina. $ — C. M. Hicken publishes a new scheme of 

 classification of the Polypodiaceae, dependent on the position of thesorus, 

 whether covering the whole under-surface, or on the nerves only, the 

 whole nerves or particular portions of the nerves, with or without an 

 involucre. The Gymnogrammea3 are kept separate from the Pterideae ; 

 the Woodsia? and Oleandreae are united with the Aspidieae. He also 

 publishes § some artificial keys of the Argentine species of Acrosticheae. 

 He describes || Elaphoglossum Porteri, a new species from the frontier of 

 Argentina and Chile ; and records six species which are additions to the 

 Argentine flora. He publishes f an artificial key to the Argentine 

 species of Vittariae, and adds two new records to the Argentine flora. 

 He publishes** artificial keys of the genera and species of the Gymno- 

 gramnieae, and ft of the Pteridese found in Argentina. 



Ferns of German Central Africa.JJ— G. Brause and G. Hieronymus 

 give an account of the ferns gathered by J. Mildbraed during the ex- 

 pedition of Herzog Adolph Friedrich von Mecklenburg in tropical Africa. 

 In all there are 121 Pteridophyta, fourteen of which are new species or 

 varieties. The specimens were collected in the following localities : — 

 Bukoba-Bezirk, Ruanda, Rugege-Wald, Vulcan-Gebiet, Ruwenzori, 

 Beni, Gr. Kamerunberg. 



New Japanese Ferns. §§ — J. Matsumura publishes Latin descriptions 

 of seven new species and three new varieties of Japanese ferns, collected 

 in Liukiu, Formosa, Nippon, etc., and determined by H. Christ.
