Rock-rose - cistus salviifolius - Genesis 37:25, 43:11
A species of the rock rose was the source of laudanum gum, one of the ingredients of the incense myrrh. It grows on rocky hillsides of the Holy Land, and it is said that the laudanum was first found attached to the beards of goats that had been cropping the plant in the heat of the day, at which time the gum comes out in certain seasons of the year.
