New Arrivals in the Plant-world of Middle Europe during- 

 the last Fifty Years. By Dr. F. Hock (Beih. Bot. Cent. bd. x. ht. 4 

 and 5, pp. 284-800).— The paper contains a great many new records for 

 such plants as Claytonia 2)erfoliata, CEnothem spp., &c., and also records 

 as a new species Geranmm Endressi, from the Pyrenees, which is 

 beginning to establish itself at Bonneville. It is chiefly interesting as 

 showing how plants from almost every part of the world can establish 

 themselves in Europe {e.g., Patagonia, Japan, Alaska, and the Caucasus).

New European Plants {Beih. Bot. Cent. bd. xi. ht. 4, pp. 261-281).— 

 Dr. Hock continues his list of new localities of European weeds and intro- 

 ductions. Two new species, Papaver commutatum and Sophora japonicaj 

 are recorded. The new localities form a long list, which shows that many 

 American plants are well able to establish themselves in Central Europe.
