 are really distinct from or are a mere state of the present species.

I suspect this must be Dr. Arnott's M. Ceylanica, which, having been de- 

 scribed, as he states, from a single specimen, may not indicate the typical cha- 

 racter of the species.

The fruit of this species closely resembles Ga^rtuer's B. costatns (De IVuct, 

 tab. 187) as regards the size 'and form of the segments of the enlarged calyx, but ' 

 differs from it essentially in the constriction beneath these. Froml). /d?m, Hamilton, 

 the only other species with which it can be confounded, its costate or angled fruit 

 would seem sufficiently to distinguish it. 



A gum-resin and wood-oil are obtained from this and the species following.

This species is well distinguished by its large hispid leaves, one of which in 

 my collection, from a young tree, is 19 inches long and 9 inches wide, with a 

 petiole 24 inches long. "T!ic enlarged calyx-lobes arc 6-7 inches long.
