This sparse _Guatteria sumatrana, Miq., in its leaves; but that species has 
much larger flowers. But this is still more allied to Guatteria hypoglauca, Miq., 
from which it differs by its much larger fruit. The plant named P, hypoleuca by 
Kurz in his Forest Flora of Burmah is, as he himself informed Sir J oseph Hooker in. 
a letter, really P. sumatrana. © Neither species, nce, appears to me to occur either 
in the Andamans’ or Burmah.
