--><p><i>Hemerocallis</i> is important economically as medicinal, poisonous, edible, and/or horticultural plants, which have been in Chinese culture for thousands of years (W. Erhardt 1992). Hemerocallin, a root neurotoxin, can be both poisonous and useful medicinally as an analgesic, diuretic, arsenic-poisoning antidote, and treatment for schistosomiasis (J. A. Duke and E. S. Ayensu 1985; W. Erhardt 1992; Hu S. Y. 1968). In Asia, flowers (buds and perianths), shoots, and tuberous roots (following suitable preparation) are important foods (G. Kunkel 1984). Daylilies are among the most popular North American garden plants. Registered cultivars of <i>Hemerocallis</i> now exceed 38,000, including more than 13,000 named clones of <i>H. fulva</i> (G. Grosvenor 1999; R. M. Kitchingman 1985; R. W. Munson Jr. 1989; W. B. Zomlefer 1998).</p><!--
--><p><i>Hemerocallis</i> has been included in a broadly circumscribed segregate family Hemerocallidaceae with 13–18 genera mainly from the Southern Hemisphere, especially Australia (W. B. Zomlefer 1998; H. T. Clifford et al. 1998), or placed alone in a monotypic Hemerocallidaceae (A. L. Takhtajan 1997).</p><!--
--><p>The dwarf, yellow-flowered <i>Hemerocallis</i> minor P. Miller, grass-leaf daylily, has been reported as a local escape in Oregon.</p>
