ADDITIONAL OBSERVATIONS. 
Read November 21, 1820. 
Since my paper on Rajfflesia , or the Great Flower of Sumatra, 
was read to the Society, further information respecting it has 
been received from Sir Stamford Raffles and Mr. Jack, which 
will form an important addition to my former account. 
Sir Stamford, in a letter to Mr. Marsden, states the following 
particulars: 
“ I find the Krubut or Great Flower to be much more general 
and more extensively known than I expected. In some districts 
it is simply called Ambun Ambun. It seems to spring from the 
horizontal roots of those immense Climbers, which are attached 
like, cables to the largest trees in the forest. We have not yet met 
with the leaves. The fruit also is still a desideratum. It is said 
to be a many-seeded berry, the seeds being found in connection 
with the processes on the summit of the pistillum. I have had 
buds brought in from Manna, Sillibar, the interior of Bencoolen 
and Laye ; and in two or three months we expect the full-blown 
flower. It takes three months from the first appearance of the 
bud to the full expansion of the flower; and the flower appears 
but once a year, at the conclusion of the rainy season.”
