[1701] The Myrtus latifolia Romana of Bauhin. It yields an essential oil, and by its decoction might give a fixed oil, in small quantity, but very odoriferous. As boiled with olive oil, he treats it as a volatile oil.
[1702] See B. xxv. c. 100. This myrtle is the Ruscus aculeatus of Linnæus.
[1703] See B. xiii. c. [29], and B xxiii. c. 45. A volatile oil might be extracted from the citrus, if one of the thuyæ, as also from the cypress.
[1704] See B. xxiii. c. 45. It is a fixed oil, still considerably used in some parts of Europe.
[1705] From the Greek καρύα, a “walnut.”
[1706] “Pitch oil.” See B. xxiv. c. 11. This would be a volatile oil.
[1707] See B. xxiii. c. 45, also B. xiii. c. [35]. Fée is of opinion, that as no fixed oil can be extracted from the Daphne Cnidium or Daphne Cneorum, Pliny must allude to a medicinal composition, like the oil of wild myrtle, previously mentioned.
[1708] A fixed oil. See B. xii. c. [36]. The seeds were used for making it. See B. xxiii. c. 45.
[1709] See B. xii. c. [51], and B. xxiii. c. 45. The leaves of the Lawsonia are very odoriferous.
[1710] The myrobalanus, or ben. See B. xii. c. [46], and B. xxiii. c. 46.
