This beautiful tree, now presented to the reader, is the production of the south and S. W. parts of Abyssinia. It is very frequent, and, with the ebony, almost the only wood of the province of Kuara, of which it bears the name; indeed in all Fazuclo, Nuba, and Guba, and the countries where there is gold. It is here designed in its natural size both leaves, flowers, and fruit, the whole so plainly, that it is needless to descant upon its particular parts, well known to naturalists. It is what they call a Corallodendron, probably from the colour of its flowers or of its fruit, both equal in colour to coral.

Its fruit is a red bean, with a black spot in the middle of it, which is inclosed in a round capsula, or covering, of a woody nature, very tough and hard. This bean seems to have been in the earliest ages used for a weight of gold among the Shangalla, where that metal is found all over Africa; and by repeated experiments, I have found that, from the time of its being gathered, it varies very little in weight, and may perhaps have been the very best choice that therefore could have been made between the collectors and the buyers of gold.

I have said this tree is called Kuara, which signifies the Sun. The bean is called Carat, from which is derived the manner of esteeming gold as so many carats fine. From the gold country in Africa it passed to India, and there came to be the weight of precious stones, especially diamonds; so that to this day in India we hear it commonly spoken of gold or diamonds, that they are of so many carats fine, or weight. I have seen these beans likewise from the West-Indian islands. They are just the same size, but, as far as I know, are not yet applied to any use there.
