limited to keep them all distinct by adequate definitions ; and this 
is also the case with what is termed the aril of the seed. But some- 
times this term is applied to parts which obviously have no claim to 
it: thus, for instance, what Gaertner gives as an instance of Arilius 
baccatus in the Litchi (Scytalia chinenm G.) is nothing else but 
the pulp of this delicious fruit, which the same author improperly 
calls a Bacca cjsuccu : this pulp, when the fruit becomes dried, 
separates from the hard outward skin in all points, except at the 
base, and, concentrating round the kernel, exhibits the shape in 
which it is represented in the incomparable work of Gaertner. 
The only species of the genus Durio is that highest of all fruit- 
trees, known by the names of Durion and Dureyn. It is not found 
in the western parts of India, but begins in Malacca, and is con- 
tinued on through Java, Madura, Borneo, the Celebes, and all 
the Moluccas. Rumpf and other ocular witnesses describe its 
thin and spreading head as supported by an angular and as it 
were winged stem, covered with an even and greyish yellow 
bark, which distinguishes this tree among all others. The leaves 
are alternate, from four to five inches in length, oblong, acumi- 
nate, entire, rather plaited at the base, above smooth and of a 
deep green hue; below covered with minute rust-coloured scales, 
and marked by a strongly elevated longitudinal rib, emitting di- 
stinct and arcuate lateral branches. Their stalks are an inch 
long, fleshy, swoln, and likewise covered with minute scales. No 
stipules were observable in those small branches which fell under 
my examination, but it appeared as if there wvxv some traces of 
their former existence. The inflorescence of the Durion is such 
as we see in all trees bearing heavy fruit, as in the Jack, Bread- 
fruit
