A tree thirty feet high, on the margins of the streams falling into the Keri-Keri river. — 1826, A. Cunningham. Of this very remarkable plant the tree bearing the female fructifi-cation has not been discovered in its native country. I have, never-theless, not] only placed it in Mr. Brown's family Atherospermece, to which it most assuredly belongs, as indicated by its opposite serrated leaves and by the structure and mode of dehiscence of its anthers, which, however, accord with those of the Laurince, but I have re-ferred it to Pavonia of Ruiz and Pavon, of which it appears a second species, although it is dioecious, and the female flower and fruit re-main yet to be examined.
