  • lambertiana: named by David Douglas to honor Aylmer Bourke Lambert (1761-1842), an English botanist who specialized in research on pines, author of the A description of the genus Pinus (1803).  Douglas named the pine to honor Lambert befor he actually saw it. See The Discovery of Sugar Pine.
  • The common name, Sugar Pine, is a reference to the sweetish resin that exudes from cut or burned heartwood.  Native peoples used the large, rich, oily seeds of Sugar Pine as a food source and the sugary sap exuded from wounds as both food and medicine, the sap has laxative properties.  The sweet exudate is pinitol, a methyl ester of a sugar alcohol namely, 3-O-methyl-D-chiro-inositol, it is now known to have "insulin sensitizing characteristics" and is obtained from soybean for commercial uses.
