orange, often spotted with brown or purple; perianth funnelform or 

 campanulate, the segments separate; anthers linear, versatile; stigma 

 capitate, 3-lobed; capsule 3-celled, dehiscent. 



Key to the species 



1. Perianth clear lemon yellow, usually finely spotted inside with darker color, 

 the segments lanceolate, very acuminate, tapering gradually into the claws, 

 8 to 10 cm. long 1. L. parryi. 



1. Perianth red or reddish orange, coarsely purple-spotted inside, the segments 

 lanceolate to ovate and somewhat rhombic, obtuse or acutish, abruptly

1. Lilium parryi S. Wats., Davenport Acad. Sci. Proc. 2: 189. 1878. 

 Huachuca Mountains, Cochise County {Palmer, Pringle, Goodding) , 



Santa Rita Mountains, Pima County (Pringle in 1881), growing in 

 rich soil along streams, May to July. Southern Arizona and southern 

 California. 



Lemon lily. One of the handsomest and showiest plants of Arizona, 

 apparently rare. The flowers are fragrant. 



2. Lilium umbellatum Pursh, Fl. Amer. Sept. 229. 1814. 



A specimen collected by E. Palmer in 1869, labeled "Arizona," 

 without definite locality, seems to be the only basis for including this 

 lily in the flora of the State. The range of the species is Ohio to 

 Alberta, south to Arkansas, New Mexico (and Arizona?). 



12. FRITILLARIA. Fritillary 



Flowering stem from a thick-scaled bulb, leafy, bearing 1 or few 

 nodding flowers; leaves alternate, linear; perianth campanulate, of 6 

 separate segments not more than 2 cm. long, greenish yellow mottled 

 with maroon; style 3-cleft, the linear lobes introrsely stigmatic. 



Several species of this genus are cultivated as ornamentals. A 

 California species, F. birflora, is known as missionbells. 



1. Fritillaria atropurpurea Nutt., Acad. Nat. Sci. Phila. Jour. 



7: 54. 1834. 

 Navajo, Coconino, and Gila Counties, rich soil in woods, 6,000 to 

 8,500 feet, April to May. North Dakota to Washington, south to 

 New Mexico, Arizona, and California. 



13. CALOCHORTUS. 22 ^ Mariposa 



Flowering stems from tunicate bulbs, subscapose, simple or sparingly 

 branched; leaves few, narrow, alternate; flowers solitary, or few in a 

 terminal inflorescence, large and showy; outer perianth segments 

 green, sepallike, glandless, the inner segments larger, petallike, each 

 with a large hairy gland near the base. 



The mariposas are among the most beautiful of Arizona wild flowers, 

 their petals exhibiting a range of colors from pale yellow to nearly 

 scarlet, and from whitish to deep lavender. The rather large bulbs were 

 eaten by the Hopi and Navajo Indians. It is stated that the Mormon 

 pioneers of Utah also used the bulbs of the sego-lily (C. nuttallii) as 

 food in times of scarcitv.
