Dr. Arnott on the Genus Rhizophora. 367 



he only quotes Malabar as its native country. As, however, 

 Blume first limited the species, I have allowed the name to 

 remain with the Molucca plant. Blume quotes Rheede's H. 

 Mai. vi. t. 33, as well as Rumplr's figures, from which I pre- 

 sume that this species ought to be compared with B. malaba- 

 rica. 



In Rumplr's work there are some discrepancies between 

 the description and figure ; thus it is said that the calyx has 

 8 — 10 or 11 patent segments that are finally re flexed, while in 

 the figure there are at least 10 segments erect, even when in 

 fruit. The tigellus is said to be neither angled nor striated, 

 but is represented in the figure slightly furrowed. The pe- 

 duncles, according to both figure and description, are one- 

 flowered, which circumstance would seem to remove it from 

 B. malabarica and its allies.

I feel uncertain if this be Blume^s plant, on account of his 

 reference to Rumplr's Hortus Amboinensis : according to that 

 work the peduncles are usually two-flowered, the calyx seg- 

 ments 5 in the description, or as many as 8 or 10 in the mi- 

 serable accompanying figure, and the germinating radicle or 

 tigellus cylindrical and striated, which is not the case with the 

 Malabar species.
