Britten, J., The History of Aiton's „Hortus Kewensis". 

 (Journ. Bot. L. p. 1 — 16. (suppl.) 1912.) 



The author draws attention to the fact that neither of the Aitons 

 wrote the botanical descriptions of the new species published in the 

 ■Hortus Kewensis'. The editors were Dryander ed. 1, and part 

 ed. 2. and Robert Brown latter part ed. 2. Many remarks are 

 made on the correct method of citation of the names published in 

 the Hortus Kewensis. Conclusive evidence is given that Robert 

 Brown was the author of the Cruciferae {Tetradynamia) although 

 his name did not appear in the text. The Epitome (1814) of the Hortus 

 Kewensis seems to have been entirely the work of Richard Cun- 

 ningham, who was also responsible for the actual preparation of 

 the second edition for press. M. L. Green (Kew). 



Chamberlain, C. J., Two Species of Bowenia. (Bot. Gaz, LIV. 

 p. 419-423. 1912.) 



The author recognizes two species of Bowenia, namely B. spec- 

 tabilis Hook f. and B. serrulata Chamb. {B. spectabilis var. sermlata 

 Andre). J. M. Greenman.

 Catalogue of all the plants collected by G. Forrest,

 Tibet in'the Years 1904. 1905, 190 6. (Notes Roy. Bot. 

 Gard. Edinburgh. XXXIV. p. 241—298. 1913.) 



The present contribution concludes the numerical catalogue of 

 the plants collected by Forrest in 1904 — 1906. The earlier parts 

 of the enumeration appeared in Nos. XXXI, XXXII and XXXIII

 Bot. L. Supplement to Aug. and Sept. 1912. p. 1—24.) 



In the introduction attention is drawn to the resemblance of 

 this family to others, notably Ericaceae, Compositae, and Thynielae- 

 aceae. Its xerophytic characters are discussed and it is pointed out 

 that Kirchner lays great stress on the corky leaf-tip maintaining 

 that it is one of the most characteristic features of the family. The 

 distribution (which is entirely South African) is outlined and a 

 key to the genera given. The following new species are described: 

 Berselia Biivchellii, Nebelia tulbaghensis, Tittmannia Oliveri, T. prui- 

 nosa, T. thesioides, T. massoniana, Raspalia Schlechteri, Pseudo- 

 baeckea gracilis, Staavia Brownii. M. L. Green (Kew). 



Dümmer, R. A., Pearsonia. A new genus of Leguminosae. 

 Journ. Bot. L. p. 353—358. 1912.) 



The new genus Pearsonia belongs to the iribe Genisteae and is 

 intermediate between Lotononis and Pleiospora. At present the genus 

 contains 11 species entirely South African. Some new combina- 

 tions are made and the following new species described: P. Ather- 

 stonei, P. propinqua, P. podalyriaefolia. M. L. Green (Kew).
