Habit like C. albus: stems stout, usually branching in pairs: petals clear yellow, very strongly inarched so that the tips overlap each other much like a child's pin-wheel; gland lined with stiff hairs that cross each other; petals margined with a line of stiff hairs. Cent, and N. Calif.
Possibly C Benthamii x C. amabilis. stems several, freely branched, bearing 15-20 flowers: Ivs. narrow-lanceolate: flowers erect, 1 in. across, straw-yellow, inner surfaces covered with long silky sulfur-tinted hairs and a few shorter crimson hairs deep down in the cup; petals rounded and very hooded. Apparently of garden origin.
bb. Flowers bell-shaped, erect when open, mostly lined with hairs, the pedicels becoming recurved: stem mostly low, and flowers often more or less umbellate. Star Tulips proper. - Like the globe tulip, but smaller as a rule, and the flowers dainty open cups. All of the species resemble each other, and were first included under the name C. elegans.
Plant low (3-10 in.), very slender, usually branched: flowers white, purplish at the base, filled with silky hairs, the gland covered by a broad semi-circular scale: caps, long-elliptic. Calif.,north. B.M. 5976 (as C. elegans). - Variable. variety major, Hort. Twice as large in all its parts: flowers lighter colored. variety roseus, Hort. Flowers tinged rose.
stems 7 in. high, very flexuose, dividing into pairs: leaves linear-lanceolate: flowers nearly erect, yellow, the segments 1/2in. long and brown at the base. Sierra Nevadas, in Calif. B.M. 6475. J.H. III. 30:549. variety Wallacei (C. Wdllacei, Hort.). Claw of the petal dark red or nearly black.
Similar to small plants of C. Maweanus, but lined and dotted with blue: low, 2-5-flowered, the pedicels very slender; perianth ciliate inside: caps, nearly or quite orbicular. Calif., in the Sierras. Not variable.
Similar to the last: petals greenish white and purplish at base, bearded, little or not at all ciliate: gland covered by a deeply fringed scale. Ore., Idaho.
Variety nanus, Wood (C. Lyallii, Baker). Subalpine, dwarf and very slender: petals delicate cream-color, narrow and usually more acute, more hairy and ciliate. Mts. Calif., N.
stem 3-5 in. high: petals white tinged green, broadly rhombic-ovate, very deeply pitted and with the pit showing as a prominent knob on back of petal. Mt. Jefferson, Ore.
Low and branching, 3-15 in., flexuose: flowers 5-10, white; petals broadly fan-shaped, nude excepting for many white hairs just above the scale. In open grassy places around San Francisco Bay.
bbb. Flowers bell-shaped: like bb, but tall (1 ft. or more), and stoutly erect, with several fine, erect cups, similar to C. Maweanus. Giant Star Tulips. - In this splendid group the very dainty silky flowers and handsome glossy leaves of the star tulip are shown with a stout stem a foot or two high, and large flowers Unlike the others, they grow naturally in open places, and have a vigor and health which are a high recommendation.
Stout, a foot high, generally branched: petals often more than an inch long, tinged lilac, with purple and white hairs: gland without a scale: caps, broad-elliptic, acutish. Mt. Shasta, N. - Remains a long time in bloom.
Taller and stouter, 12-18 in., with umbellate straw-colored flowers N. Idaho.
Glabrous and glaucous, 8-16 in., rather stout, branching, 2- to many-flowered: flowers creamy white or purple-tinged, filled with blue hairs, gland absent. S. Ore. G.C. III. 23:395-Very handsome.
bbbb. Flowers bell-shaped, the petals naked or hairy only at the base: low: If. solitary. Meadow Tulips. - These calochortuses are natives of wet meadows. C. uniflorus and C. Vesta grow well in all soils so long as well drained, and, as garden plants, thrive everywhere. In habit they are low, flexuous and leafy. The cups are open, erect and numerous, an inch or so in diam.
Low, 2-4 in., delicate: If. solitary: flowers 1-6, umbellate, small, greenish white or pale lilac, nude except for a tuft of 2 or 3 short hairs at each extremity of scale, denticulate. Calif., in the Sierras.
Handsome species, 4-8 in. high: flowers 4-10, on long pedicels, clear lilac, hairy only at base: caps, elliptic, obtuse. B.M. 5804. - Grows naturally in wet meadows, and makes offsets very freely. Often seen in a depauperate starved form, but responds at once to good treatment.
aa. Blossoms on stout, erect pedicels, the stems stout and strict: flowers open-bell-shaped. Mariposa Tulips. - Excepting in b, the mariposa or butterfly tulips have slender, grassy, radical leaves, stiff, erect stems bearing cup-shaped flowers, and sparingly leafy and with an erect caps. Bulbs small.
B. Caps, oblong, acute-angled or winged: flowers lilac or white. These are hardy species, growing in the meadows from Ore. to Mont., where they endure much cold. They form a connecting link between the giant star tulips and the true mari-posas. Their leaves are like those of the star tulips -long, broad and glossy. Like the star tulips, also, the seed-pod is handsome, 3-cornered and winged. The stems are stiffly erect: the flowers cup-shaped, not so brilliant as the true mariposas, but very delicate: the plants are hardy, healthy and vigorous, and are to be highly recommended for cold climates.
Scape erect, but not stiff: If. solitary, glossy, narrow: flowers 1-3, large and showy, lilac, yellowish, or white, with a deep indigo blotch in the center, lined with yellow hairs. Meadows, E. Ore. to Mont, and N. E. Nev. Specimens from Yellowstone Lake are yellow. - Very beautiful and showy.
