extremely drought-resistant plant, flourishing when nearly all other 

 herbaceous plants of the desert have disappeared. 



24. Eriogonum insigne S. Wats., Amer. Acad. Arts and Sci. Proc. 14: 



295. 1879. 



Eriogonum dejiexum Torr. subsp. insigne Stokes, Gen. Eriog. 

 45. 1936. 

 Colorado River (Loew in 1874). Southern Utah, Nevada, and 

 Arizona. 



Most of the Arizona specimens in herbaria labeled E. insigne seem 

 indistinguishable from E. dejiexum. 



25. Eriogonum thurberi Torr., U. S. and Mex. Bound. Bot. 176. 1859. 



Eriogonum panduratum S. Wats., Bot. Calif. 2: 480. 1880.

 42. 1936. 



Mohave County to Graham, Cochise, Santa Cruz, Pima, and Yuma 

 Counties, 4,000 feet or (usually) lower, in sandy soil, March to June. 

 Arizona, California, and Baja California. 



One of the commonest of the small, annual, spring-flowering species 

 in semidesert areas. E. cernuum subsp. viscosum Stokes (ibid .) appears 

 to be merely a densely glandular form of E. thurberi. The type of E. 

 panduratum was collected by Lemmon, probably in Arizona. 



26. Eriogonum wetherilliiEastw., Calif. Acad. Sci. Proc. ser. 2, 6: 319. 



1896.

 West. Bot. 11: 16. 1903. 



Gila County near Roosevelt, Winkelman, and San Carlos, about 

 2,500 feet, apparently rare or very local. Known only from Arizona. 

 The type of E. capillare was collected at San Carlos (Ebert in 1893). 



28. Eriogonum subreniforme S. Wats., Amer. Acad. Arts and Sci. 



Proc. 12: 260. 1877. 

 Apache, Navajo, and Coconino Counties, 5,000 to 6,000 feet, June 

 to September. Southern Utah, New Mexico, and northern Arizona.

 White Mountains (Apache and Navajo Counties), 5,000 to 7,200 



feet, June to August. Western Texas to eastern Arizona. 



At Fort Apache it grows among junipers and live oaks {Quercus 

 emoryi), at higher altitudes probably among pines. 



30. Eriogonum alatum Torr. in Sitgreaves, Zuni and Colo. Rpt.
