I take this opportunity of expressing my obligations to Sir William Hooker for having 
kindly afforded me the opportunity of examining the flowers in a living state ; thus 
enabling me to supply some particulars with regard to colour, &c., on which little or no 
satisfactory information could be obtained from the dried specimens. I regret to find, 
however, that the plant is not likely at present to ripen its fruit at Kew. Mr. Smith 
informs me it was first introduced to the Botanie Garden in 1845, in a case sent by 
Dr. M*William from Norfolk Island, where, however, it is scarcely possible that it 
should be indigenous.
