The heads of the Sneezeweed are large and orange-yellow. They grow on stiff stems 2-6 ft. tall and bloom all summer. The plants are found in spruce forests, aspen woodlands and subalpine meadows at 9000-12000 ft. They are poisonous to stock. The common name has reference to the effect that the strong odor of the flowers have on some people. Cream Tips Hymenopappus tenuifolius Plate 41, fig. 4 The yellow heads of the Cream Tips are without ray-flowers. They grow on slender stems 1-4 ft. tall and bloom in spring and midsummer. The plants have very finely cut leaves and are found on prairies, plains and foothills at 3000-7000 ft. Taper Leaf Pericome caudata Plate 41, fig. 5 The Taper Leaf is a bushy ornamental plant covered in midsummer and autumn with open clusters of fragment yellow flower-heads. The tips of the leaves are narrowed to a long, slender point and this character is expressed in both the botanical and common names. The bushes grow 3-6 ft. high, and 3-8 ft. wide and occur on foothills and gravel-slides at 6000-8000 ft. Marigold Dysodia papposa Plate 41, fig. 6 The wild Marigold looks like a tiny form of the garden Marigold and has a similar spicy fragrance. It grows 1 in.-l ft. tall and is abundant along roadsides and in fallow fields and pastures at 3000-8000 ft.

The plants grow 1-2 ft. tall, and the bruised foliage and bulbs have the characteristic onion odor. The genus is widely cultivated and furnishes several varieties of onion, chives, leek, garlic and shallot. Spring Lily Erythronium parviflorum
