almost every pari of the Northern H emisphere and mountainous regions as far south as the Philippines. With more than three hundred species, it presents a bewildering variety of forms—from tiny beadlike plants forming mats only a fraction of an inch high to sprawling shrubs two or three feet talL Some species are deciduous, some evergreen—with fleshy, succulent leaves arranged alternately, opposite each other, or in whorls—and the small, starlike flowers of many kinds are brightly colored and displayed in large clusters.
