 and forwarded by Mr. C. C. Lacaita, F.L.S., Id Chester Square,

The sixth part of the Journal of the Botanical Society of South 

 Africa ( L920) contains a paper by Mrs. L. Bolus on the Composited 

 of Kirstenbosch, with a clavis to the genera and a plate illustrating 

 the floral structure of the order. There is an article on "The Pro- 

 tection of Wild Flowers." from which it appears that " the Ordinance 

 at present in force and the Proclamation thereunder," although 

 apparently stringent, do not work satisfactorily, and suggestions are 

 offered for better enforcement. The contents are more miscellaneous 

 than the title would suggest: four pages are devoted to " Spiders at 

 Kirstenbosch." We note the appearance of a second edition of 

 Bolus's Orchids of the Cape Peninsula, prepared by Mr. Bolus and 

 the late Miss Greene — "dated l!)LS but only received in Cape 

 Town in September 1920, owing to War difficulties." 



The second part of Dr. Pole Evans's Flowering Plants of Son/// 

 Africa (Reeve, Feb.) contains figures by Miss K. A. Lansdell of 

 Preesia Sparrmannii \av.Jlara, Crassula falcata, Olivia miniata, 

 Gardenia globosa, Ricliardia Relunanni, Adenium multiflorum, 

 O'erodendrum triphyllwn, and of two of the Aloes (A. Pienadarii 

 and A. pretoriensis) recently described by Dr. Pole Evans. 



The Annals of Botany for January contains what is evidently 

 an important paper on " Some General Principles of Plant Distribu- 

 tion as illustrated by the South African Flora," by Dr. .1. M. Dews, 

 Professor of Botany in Natal University College; with papers on the 

 Anatomy of Ovule and Seed in Gnetum Gnemon, by M. G. Thoday 

 (with plate); "The Missing Link in Osmundites" by Dr. Marie 

 Stopes (1 plate) ; " On the Pollination Mechanism of Incarvillea 

 Delavayi," by E. M. Cutting ; " Telephragmoxylon and the Origin 

 of Wood Parenchyma," by li. E. Torrey (1 pi.) ; "Life-history id' 

 Nectria galligena," by Dorothy M. Cay lev (2 pi.); "The Increase 

 in Area of Leaves and Leaf-Surface of Cucuntis satirus," by E. G. 

 Gregory; "On the Occurrence in Britain of the Ascigerous Stage of 

 a ' Brown Pot' Fungus," by H. Wormald (2 pi.). 



Rhodora for November last contains "Studies of some Boreal 

 American Cerastiums of the section Orthodon " by M. L. Fernald and 

 K. M. Wiegand. Although concerned only with the plants of the 

 region indicated, the paper should interest British botanists, as the 

 species dealt with include C. alpinum, 0. arcticum, O. vulgatum, and 

 C. arvense.
