The seed of this is very small, more so than the semen santonicum, which seems to come from a species of worm-wood. Like it the Cusso sheds its seed very easily; from this circumstance, and its smallness, no great quantity of the seed is gathered, and therefore the flower is often substituted. It is bitter, but not nearly so much as the semen santonicum.
The Cusso grows seldom above twenty feet high, very rarely straight, generally crooked or inclined. It is planted always near churches, among the cedars which surround them, for the use of the town or village. Its leaf is about 2-1/4 inches long, divided into two by a strong rib. The two divisions, however, are not equal, the upper being longer and broader than the lower; it is a deep unvarnished green, exceedingly pleasant to the eye, the fore part covered with soft hair or down. It is very much indented, more so than a nettle-leaf, which in some measure it resembles, only is narrower and longer.
These leaves grow two and two upon a branch; between each two are the rudiments of two pair of young ones, prepared to supply the others when they fall off, but they are terminated at last with a single leaf at the point. The end of this stalk is broad and strong, like that of a palm-branch. It is not solid like the gerid of the date-tree, but opens in the part that is without leaves about an inch and a half from the bottom, and out of this aperture proceeds the flower. There is a round stalk bare for about an inch and a quarter, from which proceed crooked branches, to the end of which are attached single flowers; the stalk that carries these proceeds out of every crook, or geniculation; the whole cluster of flowers has very much the shape of a cluster of grapes, and the stalks upon which it is supported very much the stalk of the grape; a very few small leaves are scattered through the cluster of flowers.

The coral itself is of a greenish colour, tinged with purple; when fully blown, it is altogether of a deep red or purple; the flower is white, and consists of five petals, in the midst is a short pistil with a round head, surrounded by eight stamina of the same form, loaded with yellow farina. The cup consists of five petals, which much resemble another flower; they are rounded at the top, and nearly of an equal breadth every way.
