Groups of small parenchyma 

 cell.-, with structure similar to 

 hat of the middle mesocarp, 

 are found between the bundles. 

 The numerous large bundles 

 make up the bulk of the ma- 

 ture mesocarp, the anasto- 

 mosing branches forming the 



libro 



us network. Into each 



spines passes a small 



of the 



bundle which connects with 

 this netted system. 



Latex tubes are present in 

 the young fruit, but very few 

 or none are found with the 

 dry bundles of the mature 

 Pericarp. 



6. The aulocarp (Jig. 41) 

 persists on the seed as a single 

 layer of very thin-walled cells, 

 longitudinally elongated and 

 arranged side by side in groups.
