Nicholson, W. E., Hepatics in West Cornwall. (Journ. of 

 Bot. IV. N° 649. p. 10—12, London, Jan. 1917.) 



The author spent a few days in West Cornwall, in March- 

 April 1916, and collected inter alia the following interesting hepa- 

 tics: Rtccia Warnstorffii, R. Nigrella, Fossombronia Crosalsii, F. 

 Husnoti var. anglica, Dichiton calyculatum, Cephaloziella Massalongi, 

 C. Nicholsoni. Two of these — Dichiton and Fossombronia Crosalsii — 

 are new records for Britain. The author gives critical notes on 

 the species and adds a füll description of the rare Dichiton calycu- 

 latum, a plant which, by its superficial resemblance to Cephaloziella 

 integerrima, Lophosia excisa, &c, may possibly have been overlooked 

 by collectors. A. Gepp. 



Sim, Th. Robertson, South African Hepaticae or Liver- 

 worts. (S. Afric. Journ. Sc. Comprising the Rep. of the S. Afri- 

 can Assoc. for the Advanc. of Sc. Pretoria 1915. XII. p. 426—447. 

 Cape Town, May 1916.) 



The author gives a general introductory account of the macro- 

 scopic appearance of the South African Hepaticae, and of their 

 ecology and reproduction, with a discussion of the questions of 

 Variation and migration, and a history of South African hepatico- 

 logy. He is collecting materials for a Handbook of South African 

 Bryophyta, and in the present paper gives a Synopsis of 47 genera 

 and 163 species, furnishing short descriptions of the Orders, fami- 

 lies and genera, bat not of the species. A. Gepp. 



Bews, J. W„ The Plant Ecology of the Drakensberg 

 Range. (Ann. Matal Museum. III. 3. p. p. 511—565. 4 pl. 3 figs. 

 1917.) 



The higher altitudes of the Drakensberg are approximately 

 3000 m. The summit-region consists of hard rocks, so that the to- 

 pography is mainly plateau and sheer cliffs. Downwards to the 

 foothills, the underlying rocks are sandstones and mudstones which 

 in numerous ravines weather into steep slopes. Three sections are 

 given showing the relationship of the plant formations to the geo- 

 logical strata. The climatic factors are outlined so far as records 

 for the Drakensberg are available. None of the peaks rise above 

 the climatic snow-line, although the main ränge is periodically 

 covered with snow. The author regards the recognition of an alpine 

 region as unworkable on the Drakensberg, because the veld 

 formation extends almost to the summits, and the cliff Vegetation 

 at 2000 m does not differ ecologically from that at higher altitudes.
