Both H. erinacea and H. trifiircata retain chlorophyll in 
the walls of developing fruits, with only H. trifiircata 
retaining chlorophyll in the mature fruit. This may enable 
the developing fruit to provide its own supply of 
photosynthates, although it is more likely that leaves are 
a major source of carbon for fruit and seed growth. Green 
developing fruits may have anti-herbivore properties, 
akin to the cryptic mimicry experienced by the mature 
fruit of Hakca trifiircata (Groom el al 1994), and other 
weakly serotinous species (e.g. H. prostrata ), whereby the 
developing green fruit are disguised within a 
background of similarly green leaves.
