different (Indian ?) species. The figure quoted by Linn, is Lob. Ic. 315, a very fair representation of P. maculatum {P. nodosum, auct.). That he confounded this and P. Persicaria is obvious, from his describing the latter as " floribus digy- nis," thus reversing the characters of the plants as now understood. It is, how- ever, most undesirable to alter these long-established names.
