FLOWERING PLANTS AND FERNS OF ARIZONA { ZM 



The species is represented in Arizona by var. denticvlata (Greene) 

 Johnston {Cryptantha denticulate Greene). 



28. Crvptantha decipiens (M. E. Jones) Heller, Muhlenbergia 8: 48. 



1912. 



Krynitzkia decipiens M. E. Jones, Contrib. West. Bot. 13: 6. 

 1910. 



Mohave and Ya3~apai Counties, south to Yuma and eastern Pima 

 Counties, 2,000 to 4,000 feet, among bushes in the creosotebush belt, 

 type from near Yuma {Jones). Southern Nevada, Arizona, and Cali- 

 fornia . 



29. Cryptantha barbigera (A. Gray) Greene, Pittonia 1: 114. 1887. 



Eritrichium barbigerum A. Gray, Syn. Fl. 2 1 : 194. 1878. 

 Krynitzkia mixta M. E. Jones, Contrib. West. Bot. 13: 6. 

 1910. 



Mohave County, southward and eastward to Greenlee, Cochise, 

 Pima, and Yuma Counties, 5,000 feet or lower, most frequent in the 

 deserts, type of K. m Ida from the Mescal Mountains {Jones). Western 

 New Mexico and southern Utah to southeastern California and north- 

 ern Sonora. 



The common (typical) form of the species has inconspicuous corollas 

 1 .5 to 3.5 mm. wide. Occurring within the range of the species in central 

 Arizona are plants with more conspicuous corollas, 4 to 7 mm. wide. 

 These represent var. fergusonae Macbride, known elsewhere only 

 from the western borders of the Colorado and Mohave deserts in 

 California. 



30. Cryptantha nevadensis Xels. and Kenn., Biol. Soc. Washington 



Proc. 19: 157. 1906. 



Mohave County to Graham and Pima Counties, mostly below 4,000 

 feet, creosotebush desert, frequently under bushes. Southern Utah 

 and Arizona to California. 



Typical C. nevadensis has very slender, frequently sinuous stems, 

 very slender calyx lobes, and narrowly lanceolate long-acuminate 

 nutlets. The var. rigida Johnston is a stiffly erect, less slender plant 

 with staffer less elongate calyx lobes and less attenuate, lance-ovate 

 nutlets. It occurs throughout most of the range of true C. nevadensis 

 in Arizona. 



9. PLAGIOBOTHRYS 26 



Annual, strigose or bristly herbs with white corollas; nutlets rugose, 

 erect or incurved, attached at or below the middle to a depressed 

 gynobase through a caruncular scar, this decurrent on the lower part 

 of" the ventral keel, or situated at the lower end of the keel and sunken 

 below its crest, or elevated to the level of the keel on a more or less 

 well developed, supra-basal, stipelike, lateral projection from the 

 body of the nutlet; basal leaves opposite or crowded into a rosette. 



Some of the California species are known as popcornrlower. It is 

 stated that the plants are grazed by sheep.
