The length of the petals is very variable in this species. Aublet figures 

 a flower with three equally developed petals but his original specimen 

 in the Banks herbarium, British Museum, shows flowers, in which 

 only one petal is well developed ; two petals are much smaller and 

 two (not noticed by Aublet) are represented only by very small 

 rudiments of about i mM. The same is the case with Versteeg's 

 specimen, mentioned above.
