— International Geographical Congress. — It has 

 been announced that the meeting will be opened on the first 

 of August, at the Tuileries, in the pavilion de Flore. 



— Cedrela sinensis. — This is a valuable hardy tree 

 from the north of China; it was named and described by 

 Adrien de Jussieu (Mem. du Mus. cChist. nat., XIX, 255, 

 294), and its introduction has long been desired. Now, it 

 appears, that this has been accomplished. In 1862, Mr. Eug. 

 Simon sent a tree from China to the Jardin des Plantes of 

 Paris, and Mr. Carriere took it to be a new species of Ailantus, 

 and published it as A. flavescens. The same writer now de- 

 clares it to be the Cedrela sinensis of Jussieu, and therefore 

 this tree has long been in Europe, though unrecognised. 

 •There is a specimen of it in the Jardin des Plantes upwards 

 of 25 feet high, with a girth of trunk of about twenty inches, 

 at three feet from the ground. It also exists in several nur- 

 series, and is known in commerce as the Yellow Ailantus, 

 which must give way to the correct appellation of Chinese 

 Cedrela.

— Glaucium Serperi. — Mr. Heldreich, Professor of 

 botany at Athens, found a new Papaveraceous plant last year 

 near the Laurium silver mines, which are being worked 

 again. He named it Glaucium Serperi and a figure of it was 

 grven in the Gartenflora of November, 1874. Tins species 

 appears to have sprung up from seed, winch have lain dor-
