CALOCHORTUS 



CALOCHORTUS 



633 



BE. Fls. bell-shaped, erect when open, mostly lined with 

 hairs, the pedicels becoming recurved: st. mostly 

 low, and fls. often more or less umbellate. STAR 

 TULIPS proper. Like the globe tulip, but 

 smaller as a rule, and the fls. dainty open cups. 

 All of the species resemble each other, and were 

 first included under the name C. elegans. 



5. Maweanus, Leichtl. Plant low (3-10 in.), very 

 slender, usually branched: fls. 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. Var. major, 

 Hort. Twice as large in all its parts: fls. lighter colored. 

 Var. roseus, Hort. Fls. tinged rose. 



6. Benthamii, Baker. Sts. 7 in. high, very flexuose, 

 dividing into pairs: Ivs. linear-lanceolate: fls. nearly 

 erect, yellow, the segms. Hin. long and brown at the 

 base. Sierra Nevadas, in Calif. B.M. 6475. J.H. III. 

 30:549. Var. Wallace! (C. Wdllacei, Hort.). Claw of 

 the petal dark red or nearly black. 



7. caerilleus, Wats. Similar to small plants of C. 

 Maweanus, but lined and dotted with blue: low, 

 2-5-fld., the pedicels very slender; perianth ciliate 

 inside: caps, nearly or quite orbicular. Calif., in the 

 Sierras. Not variable. 



8. elegans, Pursh. Similar to the last: petals green- 

 ish white and purplish at base, bearded, little or not at 

 all ciliate: gland covered by a deeply fringed scale. 

 Ore., Idaho. 



Var. 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. 



9. L6bbii, Purdy (C. elegans yar. Ldbbii, Baker). 

 St. 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. 



10. umbellatus, Wood (C. collmus, Lemm.). Low 

 and branching, 3-15 in., flexuose: fls. 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. Fls. 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 fls. 

 and handsome glossy Ivs. of the star tulip are 

 shown with a stout st. a foot or two high, and 

 large fls. Unlike the others, they grow naturally 

 in open places, and have a vigor and health which 

 are a high recommendation. 



1 1 . Tolmiei, Hook . & Arn . 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. 



12. apiculatus, Baker. Taller and stouter, 12-18 

 in., with umbellate straw-colored fls. N. Idaho. 



13. Purdyi, East. Glabrous and glaucous, 8-16 in., 

 rather stout, branching, 2- to many-fld. : fls. creamy white 

 or purple-tinged, filled with blue hairs, gland absent. 

 S. Ore. G.C. III. 23 : 395. Very handsome. 



BBBB. F Is. 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. 



14. nftdus, Wats. Low, 2-4 in., delicate: If. solitary: 

 fls. 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. 



15. unifldrus, Hook. & Arn. (C. lilaclnus, Kell.). 

 Handsome species, 4-8 in. high: fls. 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 depau- 

 perate starved form, but responds at once to good 

 treatment. 



AA. Blossoms on stout, erect pedicels, the sts. stout and 

 strict: fls. open-bell-shaped. MARIPOSA TULIPS. 

 Excepting in B, the mariposa or butterfly tulips 

 have slender, grassy, radical Ivs., stiff, erect sts. 

 bearing cup-shaped fls., and sparingly leafy and 

 with an erect caps. Bulbs small. 



B. Caps, oblong, acute-angled or winged: fls. 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 be- 

 tween the giant star tulips and the true mari- 

 posas. Their Ivs. 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 sts. are stiffly erect: the fls. 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. 



16. nitidus, Douglas. Scape erect, but not stiff: If. 

 solitary, glossy, narrow: fls. 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. 



17. Greenei, Wats. St. stout and branching, 1 ft., 

 2-5-fld.: sepals with a yellowish hairy spot; petals 

 lilac barred with yellow below, and somewhat purplish, 

 loose-hairy, not ciliate: caps, beaked. Calif, and Ore. 



18. longebarbatus, Wats. Slender, about 1 ft. high, 

 bulb-bearing near the base, with 1 or 2 narrow radical 

 Ivs., 2-branched and usually 2-fld.: fls. erect or nearly 

 so, lilac with yellow at base, scarcely hairy except the 

 long-bearded gland. Wash. 



19. Howellii, Wats. St. erect, 1 ft. or more, 1-2-fld.: 

 Ivs. very narrow: sepals ovate, short-acuminate; petals 

 yellowish white, 1 in. long, denticulate, slightly ciliate 

 near the base, brown-hairy inside, the gland yellow- 

 hairy. Ore. 



BB. Caps, oblong, obtuse-angled. 



C. Color yellow or orange or orange-red, more or less 



marked with brown and purple (except in forms 

 of C. luteus): in cult, forms running into other 

 colors. 



20. Weedii, Wood. Radical If. single, glossy, broad: 

 st. tall, leafy, bearing large orange-colored fls. dotted 

 with purple: petals triangular, square- topped : gland 

 small, hairy: bulb heavily coated with fiber. S. Calif. 

 B.M. 6200 (as C. citrinus). G.C. III. 16 : 183. Varies 

 to white. 



Var. purpurascens, Wats. (C. Plummerx, Greene). 

 Similar, but lilac or purple and very showy. Calif. 

 G.C. III. 16:133. J.H. III. 29:289. Gn. 47: 80. A 

 fine form with fl. of large size and full outline, lined 

 with long, silky yellow hairs. 



Var. vestus, Purdy. Petals much more truncated 

 and curiously fringed with brown hairs; reddish brown. 

 Santa Barbara. 



Var. obispoensis, Purdy (C. obispoensis, Lemm.). Fig. 

 748. Tall and slender, branching, very floriferous: 

 petals yellow, verging to red at the tip and less than 

 half the length of the orange-brown sepals. Calif. 

 G.F. 2:161 (adapted in Fig. 748). Odd and bizarre.
