Note 536 — BOOK XII. THE NATURAL HISTORY OF TREES.

This is most probably the meaning of Pliny’s expression—“Ergo transit in mastichen;” though Hardouin reads it as meaning that myrrh sometimes degenerates to mastich: and Fée, understanding the passage in the same sense, remarks that the statement is purely fabulous. Mastich, he says, is the produce of the Pistacia lentiscus of Linnæus, which abounds in Greece and the other parts of southern Europe. The greater part of the mastich of commerce comes from the island of Chio. It is impossible to conjecture to what plant Pliny here alludes, with the head of a thistle.
