thing is said in Rumphius, the only authority, to enable us 
to determine its genus.

This also is evidently one of the Araliae ; and, if it has 
really eight petals, as Humphius says, it is probably a 
Gastonia; but it is possible that his " octo petala'' may 
include the divisions of the calyx, as well as those of the 
corolla.

Mr Correa, according to the Encyclopedie (Sup. iii. 299), 
considers this as nearly allied to the Cookia, in which I 
entirely coincide. It differs from the Cookia in having the 
seeds covered by a succulent arillus. It seems also to have 
a considerable affinity with Nyalel of the Hortus Malaba- 
ricus (iv. 37, t. 16) ; which, however, has its flower divid- 
ed into five, and only two seeds in each berry. The two 
kinds mentioned by Rumphius seem such varieties as occur 
in all cultivated plants.

Rumphius gives no mark, except the colour of the wood, 
by which these trees could be distinguished, and this will 
scarcely be accepted by botanists : nor does he mention to 
which his figure belongs. 
Lansium montanum, p. 154, t. 56. 
No reference is made to this plant by any author that I 
know.
