EOT— Vol. II.] PUKDY—CALOCHORTUS. I49 



obovate-cuneate, with a rather narrow claw, abruptly acute or rounding above, 

 white, yellowish below, with a small round or oblong gland which is covered 

 densely with agglutinated hairs, a few long hairs scattered about the gland; 

 anthers oblong-obtuse, more or less sagittate at base, shorter than filaments; 

 capsule lanceolate, 1-2 inches long. 



Described from specimens from southern Utah, 

 C. nuttallii has the widest range of any Calochortus. It 

 is found from the western flank of the Sierras to Nebraska, 

 and from the Snake River to New Mexico. In color it 

 varies greatly and in other characters slightly. The region 

 of its habitat is too little known to enable any one to mark 

 the range of the variations definitely. In Nebraska and 

 eastern Colorado it is yellow; in many places in central 

 Colorado the color varies wonderfully from white and pink 

 to purple; from Salt Lake to Reno, Nevada, and southern 

 Utah, but one form seems to be common, that which is the 

 type here described; at Pine Valley, southern Utah, the 

 flowers are cream colored; and at Dimee, New Mexico, 

 they are orange. 



40. Calochortus leichtlinii ^ Hooker. 



Calochortus leichtlinii Hooker, Bot. Mag. Tab. 5862. 



A dwarfed or alpine form, quite different from any of the other forms, 

 often but an inch or two in height; stem more slender; anthers strongly sag- 

 ittate; petals smoky white with a dark spot. 



Found in the Sierras at an altitude of from 6,000 to 9,000 

 feet. 



There is another variety of this dwarfed alpine Calochor- 

 tus also found in the Sierras, but the description of this 

 form will be reserved until there is fuller material to draw 

 from. 



1 C. leichtlinii is included under C. nuttallii by Watson, in the Botany of California, 

 Vol. II, p. 177.
