Note 170 — DESCRIPTION OF SPECIES.

The reader must not conclude from this that soil, any more than age, will account for such differences; there is a variety of Ag. alutaceus, described by Vittadini, which he says is “endowed with a very caustic taste, smelling of pepper, and to be avoided.” The kind generally found in England is probably the same as this, which Bulliard has described under the name of Ag. alutaceus acris.
