FIGURES ILLUSTRATING THE DEVELOPMENT OF 

 THE SEED AND THE GERMINATING PROCESS 

 OF RinZOPHOKA AND BRUGUIERA 



(Natuiiil size. Drawn for convenience of description in the erccl ijosiiion. ) 



1. Rhizophora nuicronata . Fruit 33 lines (8-9 mm.) high, six to seven weeks after 



fertilisation. The micropyle is but slightly dilated, and is 

 occupied by a small plug of endosperm. 



2. ,, ,, Seed of fruit represented in Fig. i. 



3. ,, ,, Fruit5 lines (12 mm.) high, eight to nine weeks after fertili.— 



ation. Germination is about to begin. A large plug ol 

 endosperm now protrudes through the dilated micropxle, 

 but still covers the lengthening hypocotyl.
