REFERENCE TO THE PLATE.

This species of Nicotiana is called the Spanish Tobacco; and although we cannot exactly ascertain whether it is cultivated for the purpose of manufacturing into tobacco or snuff, yet there is little doubt of that being the case. The general appearance of this species very much resembles the common Tobacco plant, so well known. The most ostensible difference appears to exist in the glutinous character of the present species, whose stalks, leaves, and flowers are beset by numerous little glands, that emit a viscid juice. There is not much beauty attached to it; but, as a scarce and unfigured species, it well deserves a representation, as would any species of a genus that forms so considerable a branch in the commerce of a mercantile country. Our figure was made from a fine specimen received from A. B. Lambert, esq.
