portant distinguishing character is found in the petals, as it has already 
been sufficiently pointed opt by Arnott 1.c. p. 364: ,In the first species 
(C. Candolleana) the petals are only furnished towards the apex with about 
three stout bristles of equal thickness on each side giving to them a pal- 
mate appearance‘. But in C. Roxburghiana the petals are setoso-ciliate 
above towards their apex (fringed by numerous small bristles). Karsten 
states another good discriminating character in the position and directior 
of the sepals; I.c. p.10 he says: ,Die Kelchblatter der ersteren Art (C. 
Candolleana) bleiben ganz am Rande der Frucht inserirt und stehen ab, 
diejenigen der Ceriops Roxburghiuna riicken weit auf die Fruchtwand selbst 
hinauf und legen sich derselben an.‘ .

In foliage this species resembles Rhizophora conjugata and though 
easily distinguished when flowering sterile branches of the two species 
have often been confounded, However the leaves of Rhizophora are 
dotted beneath with minute black spots, which are not to be found 
in Bruguiera.
