correction of Mora species epithet

But Robin, he didn't ask how big, but rather what is the biggest.  Smile.

Slightly more seriously, it shows one should not trust memory.  The
correct name is Mora megistosperma (an older name is Mora oleifera).

Try 300-1000 grams fresh weight (n = 126, average 526 g, s.d., 168
g).  That is the SEED, not the fruit.  The seed is, incidentally, not
puffed up with water, but rather has the consistency and tissue
density of an avocado seed, if you want a convenient reference point.
Its very large size is more or less the evolutionary result of
leaving animal dispersal behind and moving into water dispersal, and
growing/germinating in deep shade of large trees where a high tide
leaves it, where there is a lot of space, probably all of it about
the same quality at the moment, but little light, and hoping like
crazy that someone overhead dies within a few years.   A bit of
miscellany on the natural history of the tree is pp. 280-281 in Costa
Rican Natural History, D. H. Janzen,ed., 1983 University of Chicago
Press.

Happy Sunday, Dan Janzen
