1HE principal object of the present communication i> to complete, m h 

 my materials enable me, the history of Rafflesia Anotdi, the male flower «.i 

 which is described and figured in the 13th volume of the Society^ Traa 



tions. 



The specimens from which this additional information bai been obtained. 

 as well as those formerly described, were received from the late Sir Stamford 

 Raffles; and for the drawings so beautifully representing their structure, I 

 am indebted to the same distinguished botanical painter and naturalist, who 

 obligingly supplied those already published. 



In rny former essay some observations were made on toe affinities of Hafieskb, 

 a subject on which I could not then speak with much confidence. From toco 

 knowledge as I possessed, however, I ventured to state that this genus appeared 

 to be most nearly allied to Asarince, ami especially to CV£n«#, on the one 

 hand, and on the other to Aphyteia or Hydnora, an equally remarkable para- 

 site of South Africa, but the structure of which was at that time very imper- 

 fectly understood. 



An examination of complete specimens of Hydnora africana has confirmed 

 this view; and as there are points in its structure which seem to throw some 

 light on one of the most difficult questions respecting Hqfflcsia, I have in 

 eluded an account of this genus in the present paper. 



The accompanying drawings of Hydnora africana, which so admirably dis- 

 play its structure, were kindly made from these specimens by my lamented 

 friend and fellow-traveller Mr. Ferdinand Bauer, when he revisited En 

 gland in 1824 ; they were probably the last drawings he ever made of an
