Roadside clump of bamboo, Philippine Islands. The bamboo is a very important tropical monocot. Angiosperms (Greek: angio, receptacle, and sperm, seed) form the second division of seed plants. The seeds are in- closed in a pistil which later ripens into a pod or frmt. The Angiosperms make up by far the largest part of the present vegetation of the earth. There are more than 130,000 species, as contrasted with 500 species of Gymnosperms and about 4500 species belonging to the fern group. In many forms the stamens and pistils are surrounded by brightly colored floral leaves. As compared with other groups of seed plants, a most striking diversity of vegetative and reproductive struc- tures is shown within the group. This diversity of form en- ables Angiosperms to live in all land and water habitats, from the margin of the ocean to alpine summits, and from the tropics to the polar deserts. 303.
