H a v i n g but lately become acquainted with this curious species, I am obliged to introduce it as an
appendix to the rest. Its most natural place in the genus is near P. lanceolata. For the specimens
represented in the plate I am obliged to Sir Joseph Banks, in whose herbarium the leaves are preserved,
and who has lately received fragments of the cone from Mr. Christopher Smith, Botanist to the East
India Company, at Amboina. Dr. Smith has also discovered a specimen of the leaves in the Sherardian
herbarium at Oxford, among the plants collected by Dampier. From these materials, and the account
given by Rumphius, all our knowledge of this tree is derived. What he has accidentally (as he was
ignorant ot the sexes ot plants) called the male and female trees, appear to us to be really so, and that
this species is dioecious. Elis account of the valuable resin for which it is most remarkable is here
subjoined.
1 lie follow ing is an account of the resinous substance produced by this tree, which is well known in
India under the name of Dammar-Futi, Dammar-Batu, or White Dammar, and has been thus
described by Rumphius, in his Herbarium Amboinense. (Lib. 3. cap. 10.)
Hie pellucid lesin which flows from this tree is at first soft and viscous, but within a few days it
becomes as hard as stone, and lias all the transparency and whiteness of crystal, especially that which
adheres to the trees, and it will sometimes hang from them in the shape of icicles; that which flows to
