There have been reports of pods up to eight feet (2.5 meters) in length. [ 4 ] [ 5 ] This pod, like all legumes , is a single carpel , the largest carpel of any known plant. Inside the pods are ten to fifteen seeds , each of which have a diameter of 6 cm (2.4 in) and a thickness of 2 cm (0.79 in). [ 6 ]
The pods contain within them one or two bean-like brownish-red seeds, but because they do not split open naturally, the pods need to decompose before the seeds can germinate. The seeds are about 1.5–2.5 cm (0.59–0.98 in) long with a brittle, oily coat, and are unpalatable in natural form to herbivores. [7] [9] [6]
If starting seeds in the ground, plant them where you want the tree to grow, allowing 15 to 20 feet between trees. You may wish to plant 2-3 seeds per location, removing all but the strongest ...
Vivipary – This is a feature of many mangrove trees, where the seed germinates when the seed (and fruit) remain joined to the mother plant until the radicle and hypocotyl grow, reach the ground, and establish there.

A tree whose root node has two subtrees, both of which are full binary trees. A perfect binary tree is a binary tree in which all interior nodes have two children and all leaves have the same depth or same level (the level of a node defined as the number of edges or links from the root node to a node). [18] A perfect binary tree is a full ...
The pods are moniliform, up to 26 cm (10 in) long, 8–12 mm (0.3–0.5 in) wide, woody-leathery textured, smooth except micro-puberulous between seeds. [3] The seeds are longitudinal, elliptic, 7–9 mm (0.3–0.4 in) long, dark brown, lacking an aril, funicle enlarged, are folded at the seed apex. [ 3 ]
