This genus was founded on an Australian plant by Dr. F. 
Mueller, who described it in his ‘ Fragmenta,’ iv. 153. It is 
evidently a climber, with slender branches, furnished with 
shining, glabrous, lanceolate leaves, somewhat acute at both ex- 
tremities, 3-nerved as well as triplinerved at base, reticulated, 
and upon slender petioles. The inflorescence is axillary, pani- 
culate, on a slender divaricated rachis half as long again as the 
leaves, with alternate, long, spreading branches, each again with 
alternate short branchlets bearing from five to seven others, 
which support from one to three sessile flowers on their apex : 
the flower consists of from eight to ten sepals, all orbicular, very 
concave, glabrous, the outer two ciliated on the margin, smaller 
than the others, which are subequal, submembranaceous, and 
much imbricated ; it has from eight to ten petals, half the size 
of the sepals, cuneately oblong, with the lateral margins inflected 
and embracing the stamens, subfleshy; from eight to ten sta- 
mens the length of the petals and affixed to their claw, with 2- 
lobed introrse anthers, the lobes dorsally and collaterally adnate 
to the filament, each bursting by a longitudinal furrow. I have 
had no opportunity of seeing either the female flower or the 
fruit; but Dr. Mueller states that it bears three drupes (one or 
two sometimes abortive), subglobose and stipitate, enclosing a 
hard putamen of similar shape, rounded dorsally, somewhat
