FLOWERING PLANTS AND FERNS OF ARIZONA 383 



1. Jamesia americana Torr. and Gray, Fl. North Amer. 1 : 593. 1840. 

 EdwiniaamericanaiJeller, Torre yBot. Club Bui. 24: 477. 1897- 



Mountains of Graham, Cochise, and Pima Counties, 7,500 to 9,500 

 feet, coniferous forests, along streams, and on the walis of canyons, 

 July. Wyoming to New Mexico and southeastern Arizona. 



Sometimes cultivated as an ornamental. 



7. FENDLERA 



Straggling shrubs, usually 1 to 2 (sometimes 3) m. high, widely 

 branched; leaves opposite, with linear-lanceolate to narrowly ovate, 

 entire, thickish blades, the margins often revolute; flowers large and 

 showy, mostly solitary, the petals white or tinged with purple; fruit 

 a 4-celled capsule. 



Browsed by goats and deer, to a less extent by cattle when other 

 feed is scarce. Shrub beautiful when in flower, worthy of more 

 extensive cultivation as an ornamental. 



1. Fendlera rupicola A. Gray, PI. Wright 1: 77. 1852. 



Apache, Navajo, and Coconino Counties, south to Cochise and Pima 

 Counties, 4,000 to 7,000 feet, dry rocky and gravelly slopes, March to 

 June. Southern Colorado to western Texas and Arizona. 



In northeastern Arizona, the prevailing form is yar.Jalcata (Thorn- 

 ber) Render (F. falcata Thornber) with leaf blades narrow, usually 

 strongly revolute, and green and glabrate on both surfaces. In the 

 southeastern mountains (Graham, Cochise, and Pima Counties), var. 

 wrightii A. Gray (F. tomentella Thornber) is about as common as the 

 typical form. Compared with the latter, it has the leaf blades more 

 densely pubescent and white beneath, also usually narrower and more 

 revolute. 



8. FENDLERELLA 



Small, much-branched shrubs, 0.5 to 1 m. high; leaves small, with 

 lanceolate entire blades; flowers inconspicuous, in small cymose 

 clusters; hypanthium turbinate; capsule longer than the calyx. 



1. Fendlerella utahensis (S. Wats.) Heller, Torrev Bot. Club Bui. 25: 

 626. 1898. 



Whipplea utahensis S. Wats., Amer. Nat. 7: 300. 1873. 



Coconino County (and probably) northern Mohave County, com- 

 mon in and about the Grand Canyon, 5,000 to 8,000 feet, dry open 

 pine woods, June to July. Southern Utah, northern Arizona, and 

 southern California. 



The distribution of the typical form is given above. In southern 

 Arizona, southern New Mexico, and northern Mexico occurs var. 

 cymosa (Greene) Kearney and Peebles (F. cymosa Greene) which has 

 the leaf blades commonly narrower and more pointed than in the 

 typical form. The variety occurs in the mountains of Graham. 

 Cochise, and Pima Counties, 4,500 to 6,500 feet, often on limestone, 

 May to September. The type of F. cymosa was collected in the Santa 

 Rita Mountains, Pima County (Pringlt in 1S84). The plants are 

 browsed by deer.
