"Pineapple is a plant of the natural order Bromeliacæ. The flowers rise from the center of the plant, and are in a large conical spike, surmounted by spiny leaves called the crown. The conical spike of flowers ultimately becomes enlarged and juicy, constituting the pineapple, considered one of the finest of fruits. More than 50 varieties have been produced. The plant grows in the S. portion of the United States and in Hawaii. In the islands they sometimes reach the weight of 17 pounds, though the average weight is six. Since 1883 there have been large exports of this fruit from the various islands."—(Charles Leonard-Stuart, 1911)
