228 Mr. Brown's Account of a new Genus of Plants, 



still more satisfactory, until the leaves and fructification be- 

 longing to the root to which Rafflesia is attached shall have been 

 found, its being a parasite, though highly probable, cannot be 

 considered as absolutely ascertained*. 



ADDITIONAL OBSERVATIONS. 



Read November 21, 1820. 



Since my paper on Rafflesia, 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 Krubid 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."
