152 Rhizophoracece. [Ceriops~ 



dotted beneath, petiole ^-1 in., stip. 2-3 in. ; fl. sessile 

 peduncles very short, about \ in., stout, from axils of fallen 1. ;. 

 cal.-segm. f-f in., ovate-oblong, acute, striate externally ; pet^ 

 linear, flat, glabrous, soon falling; stam. 11 (or 12) ; fruit about 

 1 in.; otherwise as in the last. 



With R. mucronata, but rather less common. Fl. Jan., Feb.; white,, 

 sep. pale green, brown outside. 



All Tropical seashores of Asia and Africa. 



By common consent this has been accepted as R. conjugaia of" 

 Linnaeus, but it is not the plant of his Fl. Zeyl. n. 181 (see Bruguierd) nor 

 of his Herbarium. He included the present species under R. Mangle, 

 which principally referred to an American one, to which the name is now 

 restricted. Rheede's plate above quoted certainly represents the present 

 species rather than R. mucronata, for which it is quoted in Fl. B. Ind.. 

 Though easily distinguished when living, the confusion in books between 

 the two is very great. 



These two Rhizophoras form, with Bruguiera gymnorhiza, the bulk 

 of the mangrove forests of the coast. The bark of all is used for tanning 

 in Ceylon, and is exported to India in small quantity.
