TENASSERIM or ANDAMAN ISLANDS, Helfer (Kew Distrib. 214). 
Branches rather slender. Leaves 3—5 by 13-2 in., pale brown when dry, shining 
above, nerves many pair, very slender, hardly distinguishable above from the prominent 
lux reticulations ; petiole $-3 in. Flowers very immature, peduncle + in., stout, 
pubescent. Sepals 4, orbicular. Stamens many; anthers extrorse. Fruit (young) 
j in. long.— The large stigma at once distinguishes this from C. subsessilis and 
assamicus. Male flowers not seen.

ranches (in fruiting specimen) very stout, woody. Leaves 6-9 by 2-4 in., 
coriaceous, dull green above when dry, paler beneath, base on one side rounded, on
