In others the wings are due to enlargements/ of some 

 or all of the sepals. Thus in GYROCARPUS JACQUINI 



(fig. 62) two of the sepals be- 

 come wings. In HOPEA 

 PARVIFLORA and DIPTERO- 

 CARPUS TURBINATA, trees 

 belonging to quite a different 

 family, we can see at once that 

 the wings are enlarged sepals, 

 which though the ovary is in 

 the flower superior, grow out 

 round and above it in the fruit. 

 And in SHOREA ROBUSTA (the 

 Sal-tree) all five sepals become 

 enlarged as wings (fig. 63). 



Then again, there are fruits 

 with tufts of hairs or hairy 

 appendages answering the same 

 purpose. In CLEMATIS and 

 NARAVELIA, the style of each 

 carpel elongates enormously in 

 fruit, and is also hairy, the 

 hairs being large and pointing
