Note 646 — BOOK XXV. THE NATURAL HISTORY OF THE WILD PLANTS.

Theophrastus, as stated by Pliny, in B. ix. c. 9, says that centaury is protected by the “triorchis” (see B. x. cc. 95, 96), and Pliny in translating the passage has made a mistake as to a third kind. Fée is probably right in his conjecture that the Centaurea centaureum is meant; though Brotier and Desfontaines look upon this as being a distinct plant, and identify it with the Rumex sanguineus of Linnæus.
