Pringsheim's "Jahrbucher" for 1875 contain papers by Castra- 

 cane on the Diatomacese of the Coal Period, a continuation of Tschis- 

 tiakoff's researches on cells, in which the development of pollen is 

 treated, and Bauke's memoir on the development of the prothal- 

 lium in Cyatheactse. The two last-mentioned papers are each illus- 

 trated with five beautiful microscopic plates drawn by the authors. 



Dr. G. W. Korber, of Breslau, has published an octavo pamphlet 

 of thirty pages in refutation of the Algo lichen theory propounded by 

 Schwendener and supported by Bornet. He denies that the hypha 

 portion of the lichen thallus consists of a fungus, and that the gonidia 

 of the lichen are Algae, and the lichen a compound organism. Dr. 

 Korber is himself a keen lichenologist, and therefore his views are 

 entitled to respect. 



Lady Barkly has published in the part of the "Cape Monthly 

 Magazine," for April, 1875 (vol. x., no. 58), a revised list, with their 

 distribution, of the Ferns of South Africa. No separate account of the 

 Ferns of the whole of the colony has appeared since the well-known 

 paper by Pappe and Pawson was published in the same magazine 

 in 1857. During the eighteen years a great deal of new territory 

 has been explored. Adopting substantially the standard of species- 

 limitation used in Hooker and Baker's Synopsis Filicum, Lady Barkly 

 admits for the colony 153 species. This includes 41 species not given 

 in the earlier list, in which species were admitted on a scale so much 

 more liberal that the total number was placed then at almost exactly 

 the same figure as now. Many of Pappe and Pawson's plants then 

 supposed to be endemic, increased knowledge has shown must be aban- 

 doned as such, and Mr. Rawson, who is now the Governor of Barba- 

 does, has very obligingly forwarded his collection of types toKewand 

 afterwards to Cape Town to be compared, so that now the ferns of the 

 colony may be considered as known very fully and satisfactorily. We 

 wish to recommend Lady Barkly's paper to our readers as a careful and 

 trustworthy enumeration. 



Dr. Lindberg has nearly finished a treatise on the Irish Hepaticae .
