There are in the Kew Herbarium seven specimens of this species, six 
from Borneo and one from the Philippines: they exhibit a great deal of 
variation in the leaves and calyx-lobes, but I cannot separate them into 
distinct species. They differ from Korthals’s description in that the 
peduncles are pubescent and the stigmas subglobose ; they seem to agree 
with the spceimens in the Leiden Herbarium, none of which, however, 
are in fruit. Although the calyx-tubes cohere, in every other respect 
they differ from Sarcocephalus ; they do not thicken in the free portion 
as in Sarcocephalus, so that the fruit, instead of presenting cupular 
depressions, presents conical elevations. The manner in which the 
endocarp in the upper part of the fruit becomes thickened and pithy is 
quite peculiar; it perhaps aids the fruit to float on the surface of the 
water. The species generally grows by the side of rivers. In the 
Philippine specimen the endocarp separates readily, but in the Bornean 
specimens it is firmly attached to the calyx-tube. In most of the 
specimens some of the branchlets have hollow swellings which have been 
inhabited by ants. I suspect that this plant is the Sarcocephalus macro- 
cephalus of K. Schumann, of which I have not, however, been able to 
find any description.
