and Miscellaneous Particulars. 
This drupe is large, subovate, and incloses a woody nut. The bark, which has a mucilaginous sweetish taste 
and a disagreeable smell, was first noticed as a vermifuge by Peter Duguid ; but Dr. Wright, who resided a 
long time at Jamaica, has communicated the fullest information concerning this tree. According to him, 
the bark is powerfully medicinal ; and its anthelmintic effects have been established at Jamaica by long 
experience. 
1518. Dipterix. From li;, double, and ^rn^v^, a wing, in allusion to the two appendages of the calyx. A tree 
much branched at top, with large alternate pinnate leaves, and racemes of flowers succeeded by almond-like 
fruits. The kernels of these are very fragrant, and are put by the Creoles into chests of clothes, in order to 
drive away insects, and communicate a grateful odor. They are in their own country called Tonga, and are 
the sweet-scented seed sold in shops under the corrupted name of Tonquin bean, for perfuming snufF and other 
substances. Ripened cuttings root in sand in moist heat. 
1519. Farivoa. The name of the tree in Guiana. A very handsome tree. 
1520. Amerimnum. One of the names given to the Houseleek by the Greeks. It is derived from «, priva- 
tive, and fji,i^ifji,v(x,, care, because the plants require no attention. It is not easy to tell why the name was applied 
to this genus, which has nothing in common either with the Houseleek or its ancient name. A. Ebenus is 
common in the West Indies, and the wood is sent to Europe under the name of American Ebony. Though 
not the true ebony, yet being of a fine greenish-brown color, and polishing well, it is much coveted by the in- 
strument makers, and is of a very hard durable nature. The flowers of Amerimnum latifolium are yellow, 
and smell like new hay. In our stoves the species may be treated like Pterocarpus. 
1521. Erythrina. From E^t/S-^aj, red ; nearly all the species being remarkable for the brilliant scarlet color of 
their flowers. The species are small trees, prickly or unarmed, or else shrubs, sometimes almost herbaceous ; 
leaves, as in Dolichos, ternate, stipulaceous, the petiolules jointed and awned, or glandular, very seldom simple j 
flowers in fascicles from the axils, or in spikes at the end of the stem and branches, often scarlet. [Jussieu.) 
In our stoves they thrive well in a light loamy soil. " The best way to flower them," Sweet observes, " is 
to place them on a dry shelf in winter, when they have no leaves, and give them scarcely any water ; when 
they show flower-buds, they may be plunged in a moist heat, which will make the flowers finer than they
