The name “Golden Eye” is a direct translation of the scientific name of the genus. The flower-heads are entirely golden-yellow, ray-flowers as well as disk-flowers, and they bloom in midsummer. The plants are low-growing, 1-2 ft. high, and occur on prairies and gravel-slides and in aspen woodlands at 3000-10000 ft. Gum Weed Grindella squarrosa Plate 38, fig. 8 The foliage of the Gum Weed oozes a sticky substance that gives the plant its name. The flower-heads are golden-yellow and bloom from midsummer to autumn. The plants are branched and grow 2-4 ft. tall, along roadsides and in pastures at 3000-7000 ft. The entire plant is used in medicine for certain lung troubles, and a salve is made from it that is helpful in poison-ivy poisoning. Cone Flower Ratibida columnaris Plate 39, figs. 1, 6 The fertile flowers of the Cone Flower are grouped in cone-shaped heads, which give the plant its name. The broad ray-flowers vary in color through shades of pure yellow to brilliant orange-red, and this form is sometimes cultivated in home gardens. The plants grow 1-3 ft. tall on prairies and plains at 3000-7000 ft., and bear flowers all summer. Golden Glow Rudbeckia laciniata Plate 39, fig. 2 The native Golden Glow is related to the popular Golden Glow of the garden. It is a striking plant, 3-6 ft. tall and bears many large flower-heads with long, spreading or drooping yellow rays. They bloom in midsummer and are found in meadows and along brook-banks in aspen and fir forests at 5000-8000 ft. Black-eyed Susan Rudbeckia hirta Plate 39, fig. 4 Black-eyed Susan, unlike its near relative Golden Glow, has a reddish-brown, almost black, center and orange-yellow rays. It is cultivated also, but occurs naturally in meadows and bogs and along brook-banks at 5000-11000 ft. The plants are 1-4 ft. tall and bloom all summer. Rayless Thelesperma Thelesperma gracile Plate 39, fig. 3 As the name indicates, the Rayless Thelesperma has heads of fertile flowers only, ray-flowers being lacking. The heads are grouped in graceful clusters on slender stems, 2-4 ft. tall, and bloom all summer. The plants occur on prairies and plains at 3000-8000 ft. Rayed Thelesperma Thelesperma trifidum Plate 39, fig. 8 The Rayed Thelesperma, in contrast to the one above, has broad yellow ray-flowers around a yellow center. It is a relative of Coreopsis and should also be cultivated in home gardens. The plants are 1-3 ft. tall and are found along roadsides and in pastures and fields at 3000-7000 ft., blooming all summer. [Illustration: Plate 39 ASTER FAMILY
