Cloves, the dried flowerbuds of a type of myrtle tree, grew on six similarly selective islands some two hundred miles to the north in the same chain, known to geography as the Moluccas but to history as the Spice Islands. Just to put this in perspective, the Indonesian archipelago consists of sixteen thousand islands scattered over 735,000 square miles of sea, so it is little wonder that the locations of fifteen of them remained a mystery to Europeans for so long.
