RHIZOPHORACE^. 5^3 



Even the tendency to have lobed, toothed, or setigerous petals, which 

 so generally prevails in Rhizoplioracece, is indicated in the summit of 

 the petals of Crossostylis. It should be mentioned that the evident 

 resemblance of Crossostylis to the preceding genus had not escaped the 

 notice of Mr. Rich, who, however, was not aware of the relationship 

 of either with the Bhizophoracece.

for the peculiar economy of the germination of the embryo of the Mangroves is a 

 special, maritime, not an ordinal character, and one which in other cases (as in Aroi- 

 dece) belongs to families which generally have albuminous seeds, as Mr. Brown has re- 

 marked.
