The foregoing description of this interesting, and hitherto 

 obscure plant, is taken from the original specimen preserved in 

 the Linneean herbarium, which together with the extensive col- 

 lections and library of the late Sir James Edward Smith have 

 now become the property of the Linnean Society. The acqui- 

 sition of these collections will add much to the honour and credit 

 of the Society, and will tend greatly to advance the science of 

 Natural History in this country. Now that the number of spe- 

 cies is so much increased, it is impossible in extensive genera 

 to determine satisfactorily the older ones, without having recourse 

 to the authentic materials on which they were founded.
