THE output of botanical work in connection with the Belgian 
Congo continues with astonishing energy, under the editorship of 
rof. E.de Wildeman. We have just received the first fascicle of 
the Flore du Bas- et du Moyen-Congo, which is to form vol. 3 of 
the botanical portion of the Annales du Musée. It is sumptuously, 
not to say extravagantly, printed in large quarto and illustrated by 
twenty-seven well-executed plates of the more interesting novelties, 
as well as by figures in the text. Among these are Thonnera, a

Series” of the Kew Bulletin, published in September 1908 under 
the title New Genera and Species of Cyperacee, of which no co 
has reached us. The plates, however, consisting as they largely 
do, of dissections, come within the definition of publication laid 
down by the Vienna Rules; most of them are drawn by Mr. C. H
