PLANTS FROM SOUTHEASTERN UTAH. 32I 



126. Eriogonum divaricatum Hook., Journ. of Bot. & 

 Kew Gard. Miscell., v, 265. 



Type locality: " On saline clayey soils, within the high 

 calcareous hills of the upper Colorado." 



Abundant in the same kind of soil as the type, along 

 the San Juan River, in a limited space, where probably 

 the soil suited its needs. 



127. Eriogonum flexum Jones, Zoe, ii, 16. 



Type locality: "On the Moencoppa, in northern Ari- 

 zona. It grows on dry mud flats." 



This is the plant that I reported (Zoe, iv, 10) as E . 

 glandulosum, from Grand Junction, Colorado, and Mon- 

 tezuma Canon, Utah, not far from where the present col- 

 lection was made. The environment was similar to that 

 of the type. 



128. Eriogonum Jonesii Watson, Proc. Am. Acad., xxi, 



454- 



Type locality: " Cosnino, Arizona, a station on the 

 Atlantic & Pacific Railroad, near the San Francisco Moun- 

 tains." 



This species is variable in size, shape and amount of 

 tomentum, color of flowers, and expanse of cyme. It 

 is very close to some forms of E. corymbosum. It was 

 distributed quite extensively from Butler Spring to 

 Willow Creek. I have the three following forms: 



1 29. This was collected on Barton's Range, with broadly 

 elliptical leaves, blade about 3 cm. long, 2 cm. wide, on 

 petioles 1-2 cm. in length, margin revolute, crinkled, 

 tomentose on the lower side, greener above; flowers 

 white; involucres sessile or shortly pedicelled; corymb 

 3-forked, except on the dichotomous ultimate branchlets. 

 This grows in bunches from a woody base to a height of 

 about 3 dm.
