This n'rass \\\v< formerly known as Liixiocliluii <//'/i/i(//////ii/x, and it would 

 seem to be more common in the uplands than in the coast districts, we have not met 

 with it. The onlv specimen in the Herbarium is Buchanan's ^7!>. and is a very poor 

 one. but the Director of the Koyal (iardens and H( rl iinum at Ki'W very kindly lent 

 us a better one of Buchanan's same gathering for the purpose of completing the 

 drawing.
