This singular plant is found parasitic upon old trees, in the form 
of a large irregular tuber, from which arise a few thick, short, 
fleshy branches. The Leaves are crowded at the rounded 
extremities of these branches, and are opposite, petiolate, 
obovate-oblong, with a short acumen, attenuated to the 
petiole, entire, very smooth, somewhat leathery.  Petioles 
long, roundish, inserted on a large persistent peltate knob, 
whose edges expand into a kind of stipule, ciliated along 
the margin with dense strigose fibres, and cleft above in the 
axil of the petiole. The flowers are sessile, closely disposed 
in the spaces between the stipular bases of the petioles and 
half concealed under their projecting edges. Calyx mem- 
branaceous, superior, nearly entire. Corolla white, tubular, 
quadrifid ; segments erect, rather acute; a villous ring 
within the tube immediately below the insertion of the sta- 
mens. Stamens four, shorter than the corolla, and alternate 
with its segments ; anthers white, two-celled. Style longer 
than the stamens. Stigma simple, tomentose. Ovary four- 
celled, four-seeded. Berry ovate, smooth, white with lon- 
gitudinal lines, four-celled, four-seeded. Seeds furnished 
with albumen ; embryo in its axis. 
Ons. There can be no doubt of this being the plant described 
by Rumphius, although the leaves are represented more 
acute in his figure than they are in my specimens.
