unona

Updated: May 28, 2025

It is a new species of the unona, and has the stateliness of the Uvaria zeylanica of Aublet. Its branches are straight, and rise in a pyramid, nearly like the poplar of the Mississippi, erroneously called the Lombardy poplar. The tree is celebrated for its aromatic fruit, the infusion of which is a powerful febrifuge.

I have already observed that between the tropics, the use of aromatics, for instance very strong coffee, the Croton cascarilla, or the pericarp of the Unona xylopioides, is generally preferred to that of the astringent bark of cinchona, or of Bonplandia trifolatia, which is the Angostura bark. The weather was unfavourable for astronomical observations.
