Capitanopsis, a new^ genus of Labiatae with one species C. Cloi- 

 selii, (Madagascar), is described. Also a new^ genus of Eiiphorhia-

A chem.ical investigation of this plant was undertaken in order 

 to decide definitely the nature of its active principle, and also to 

 determine whether this constituent is present in sufhcient quantity 

 to cause dealh, opinion var3'ing as to this latter point. It was found 

 that N. snaveolens contains the extremely poisonous alkaloid nico- 

 tine, and moreover that the nicotine is present in sufficient quan- 

 tity to poison stock. E. M. Cotton.

The author has named this plant Aloe snprafoliata. It is very 

 distinct from other species of the genus and has no near affinity. 

 A new section Superpositae is therefore proposed for it under Ber- 

 ger's Humiles. The leaves are exactly distichous and are superim- 

 posed one above the other in a most regulär fashion. The flower 

 spike is slender, unbranched and bears rather loosely attached 

 rose doree flowers. The plants are usually found on the tops of
