Note 40 — CHAP. XLVIII.

The name of this tree, which is so common all over this part of the world—in the forms kórna, kúrna, kúrnahí, kúrru, kírna—is one of the most widely-spread of all those names indicating objects possessing properties useful to man; and this would seem to indicate that it is not indigenous in the various regions where it is at present found, but introduced from one and the same quarter. However, on nearer inspection, this argument does not seem to be conclusive. It has certainly not been introduced into Negroland from a more northern climate, as little as the Balanites and the Cucifera, which is erroneously called Thebaica, instead of Nigritia.
