F oster The Botanizing Author Collects a Bromeliad Specimen in the Bolivian Andes Puva herzogii bears no edible fruit, yet it belongs to the pineapple family (Bromeliaceae). Though the plant is rooted to earth, it derives part of its food from the atmosphere. Spanish moss, its rootless cousin, feeds entirely on air. Mr. Foster, a plant explorer, has discovered 200 species of bromeliads, amaryllids, orchids, and cacti. He has led many plant-hunting expeditions into Latin America. The world's largest collection of living bromeliads grows in his Orlando, Florida, garden.
