Fig. 259. — The developing seedling of the mangrove. In i, 2 and 3, the 

 fruit is still hanging on the branch but the hypocotyl grows until it reaches a 

 length of about 12 inches when it drops to the earth and, striking in the mud, 

 remains standing upright, as if planted (4). At a later stage (5) roots have been 

 developed at the lower end and an epicotyl from the upper^end.
