carried further by the wind before it reaches the 



ground. 



2. The same purpose is effected in the case of 



many other plants by similar growths on the fruit. 

 Thus in ANOGEisus LATIFOLIA, the 

 ovary, which is inferior, grows out into 

 two wings. In some species of TER- 

 MINALIA, there are five such wings, 

 as also is the case with the fruit of 

 QUISQUALIS INDICA, the common 

 Rangoon-creeper, and COMBRETUM 

 where the five edges of the fruit, corre- 

 sponding to the five carpels, grow out 

 into thin wings (fig. 60). 



In HIPTAGE 

 MADOBLATA 

 (fig. 61) belong- 

 ing to quite a 

 different family, 

 the ovary which 

 is at first three- 

 celled, has in 



fruit three wings, one to each cell, but 

 only one seed. In some other cases 

 when the fruit has a wing to each cell 

 the cells separate, each with its wing 

 being then a samara. And with 



PTEROCARPUS, PONGAMIA and 

 PTEROLOBIUM, which belong to the 

 family LEGUMINOSE^E, the fruit has only one seed and 

 is expanded either at one side, or all round, into a 

 wing.
