668 RHIZOPHORACES, 
The trunks of both are supra terraneous. The first 
is a low tree, the second has scarcely any trunk, being a 
mere crown, the base of which reaches the high water mark, 
In R. odorata, the petals only embrace during estivation 
their respective stamens, they are white fleshy and sweet 
smelling. The structure of the anthers is very remarkable 
the connective is fleshy and large, the pollen is lodged in 
cavities arranged closely along its flattened sides and right 
and left with regard to the axis, these cavities or sacs have 
no mutual communication, the cuticle of the connection at 
any early period entirely continues with the substance, a 
short time before expansion separates along the flattened 
sides into unequal valves, the inner of which becomes en- 
tirely free from its original connection, except at its base, 
the outer by far the larger remaining attached by its apex and 
base. The connection is thus exposed, it presents a locular 
appearance, the areoli corresponding to the originally closed 
sacs. The inner valves ata more advanced period incline 
inwards over the style and stigma. The same organisation 
occurs in R. Mangle. 
The direction of future separation of the valves is indicated 
by a faint linear depression. Both these species have the 
same structure of roots, i. e. soft and exceedingly fine woody 
- fibre, imbedded in lax amylaceous cellular tissue. The bark 
contains in abundance hard roundish bodies, lodged in ca- 
vities of the nature of which I am quite ignorant.
