Eucalypts in Florida. By Eaphael Zon and John M. Briscoe 

 {U.S.A. Dep. Agr., Forest Service, Bull. 87; April, 1911). — In several 

 parts of the United States, particularly California, Eucalyptus growing 

 has been carried out so successfully that experiments are now being 

 undertaken as to the suitability of the tree for planting in Florida, where 

 climatic conditions seem favourable. So far the results have been 

 satisfactory, and it is anticipated that in the near future considerable 

 tracts of suitable ground will be planted with these trees. ^A. jD; W . 



Eugfenias of South Africa. By R. A. Diimmer {Gard. Chron.

Euphorbia greg-aria (Marloth), On the Latex of {Not. Konig. 

 Bot. Berlin, vol. v. No. 48, pp. 234-236; Dec. 1911).— The wax-like 

 raw material obtained from a stem of Euphorbia gregaria was tested 

 with regard to its solubility and compared in this respect with (1) 

 pure yellow beeswax ; (2) pure bleached beeswax ; (3) Japanese wax. 

 According to this examination the raw material from Euphorbia 

 gregaria has the properties of wax, but is more resinous than the 

 other kinds of wax. This resinous character detracts from its useful- 

 ness for technical purposes. No caoutchouc was found in the plant.
