The plant bearing the above Indian name, and also called Sipeeri by the Dutch colonists, furnishes the hard and heavy timber known by the name of Greenheart. The object of the present paper was to state the result of experiments made by the author on the bark and seeds of the tree, which had been found by Mr Rodic, R. N., to contain a vegetable alkali possessed of the power of checking intermittent fevers. Dr Maclagan stated that the tree was unknown to botanists. Sir William Hooker and Dr Lindley had seen the fruit and declared it to be lauraceous, but the author had been unable to find, in Rees v. Esenbeck's Systema Laurinarum, any genus or even suborder of lauraceous plants to which he could refer it.
