Most plants around us are angiosperms, commonly called the "flowering plants" One of the most noteworthy features of angiosperms is the diversity of bodies that occur in this group. Some angiosperms are ordinary herbs or shrubs or trees, but some are desert succulents (cacti), vines (grapes), parasites (mistletoe), bulbs (onions), and tubers (potatoes). Ferns and conifers are not as diverse. Angiosperms are one of the newest groups of plants. The first true plants originated about 420 million years ago, but the oldest fossils of angiosperms are only about 135 million years old.
