A small genus ot N. tropical Africa and India, including several species affording retiua 

 of commercial value, but which our material does not sutlice to identify and describe. It 

 is most desirable that specimens should be obtained in leaf, tlower, and fruit, with urapirs 

 of the resin afforded by the respective species. I have described belovr the leafy »pcci- 

 mens of several resin-producing species of the Somali country tiansmittcd to the litr Sir 

 W. J. Hooker by Col. Playfair.
