Glochidion is a genus of flowering plants in the family Phyllanthaceae, known as cheese trees or buttonwood in Australia, and leafflower trees in the scientific literature. It comprises about 170 species, distributed from Madagascar to the Pacific Islands. Glochidion species are used as food plants by the larvae of some Lepidoptera species including Aenetus eximia and Endoclita damor. The Nicobarese people have attested to the medicinal properties found in G. calocarpum, saying that its bark and seed are most effective in curing abdominal disorders associated with amoebiasis. Glochidion are of note in the fields of pollination biology and coevolution because they have a specialized mutualism with moths in the genus Epicephala (leafflower moths), in which the moths actively pollinate the flowers—thereby ensuring that the tree may produce viable seeds—but also lay eggs in the flowers' ovaries, where their larvae consume a subset of the developing seeds as nourishment.

Here is a spectacular, thought-provoking, and highly informative guide to the fascinating world of astronomy. Superb full-color photographs of scientific instruments, experiments, and innovative 3-D models reveal the discoveries and research that have transformed our understanding of the Universe. See how sailors navigated by the Sun and stars, where the asteroid belt is, how the planets and constellations were named, why the Earth was considered the center of the Universe, what a black hole is, and the hot volcanic surface of Venus. Learn how space probes photograph planets, what causes a meteor shower, what makes Mars red, why the Sun shines, where the Moon came from, how the first telescopes worked, the stages in the life of a star, and how the Earth's atmosphere sustains life. Discover what creates auroras, why the Zero Meridian is located at Greenwich in England, how the amazing early observatories were built, how Saturn could float on water, the "sound" of our own galaxy, how a comet is formed, and much, much more.
