In all tbe flowers I have examined the stigmas appeared imper- 

 fect, and although the central column of the ovarium was slightly 

 incrassated at the apex, I could perceive no trace whatever of ovules. 

 I therefore consider them as unisexual, in which I am confirmed by 

 Rheede, who says of his Tiri-itti-Canni, " fructus nulli :" in his 

 Idu-mulli, or the fructiferous plant, no stamens are figured, but 

 they are described ; probably they are abortive. Rheede figures the 

 female with thorns on the branches, but not the male, although he 

 describes them. On my specimen there are none whatever, but it 

 is the mere termination of a young branch. Rheede says of the 

 male that it is a parasitical plant, of the female that it is a lofty 

 tree : the former appears to me quite a misconception on his part. 

 The figures he has given, the one of the male flower, the other of 

 the fruit, are faithful.
