smooth, its base inserted, (as in a socket, into a large firm 
flask-shaped receptacle, which I take to be the albumen 
and vitellus of Gertner, If the seed be erect, the perma- 
nent calyx adheres to its globular base.. Perisperm 
none. Embryoinverse, Cotyledons undetermined, Plu- 
mula of along, sharp, conical shape, two-lobed ; plumula 
_within. Radicle conform to the seed, superior, the real - 
root proceeds from its apex. 
The great length of the seed of this species, gives ina 
very short time a young tree ; for if the apex from whence — 
the root issues, is only stuck a little way into a wet soil, 
or mud, the leaves quickly unfold at the opposite end, as 
mentioned by Brown in his History of Jamaica. — , 
The wood of this tree is of a dark reddish colour, hard 
and durable.
