126 Plants Collected in Southeastern Utah. [zoe 



117. ATRIPI.EX ARGENTEA Nutt. Along the San Juan 

 River and elsewhere. 



118. AtriplexNuttallii Watson (?). This differs somewhat 

 from the species and may be new. The material is hardly 

 sufficient for satisfactory determination. 



119. Grayia Brandegei Gray. Blooming plants were 

 collected on a hill near McElmo Creek. They were not far 

 enough advanced for good specimens but could be distinguished 

 from the Atriplex which they resemble. 



120. Grayia polygaloides Hook, and Arn. Common at 

 Thompson's Springs. A form with very large fruit was found 

 near McElmo Creek. 



121. Sarcobatus vERMicuLATus Torr. Widely distributed 

 along streams. Montezuma Creek. 



122. Eriogonum Thomasii Torr. Court House Wash, 

 near Moab, growing along the rocky canon walls. 



123. Eriogonum inflatum Torr. Common on the desert 

 plains and the canon sides. It is called trumpet-weed at Moab. 

 The inflation is almost globular in the plants of the plains, but 

 long and narrower on the hill-side forms, which also grow much 

 taller than the others. The inflated portion is empty, not con- 

 taining a drop of moisture. Growing with the inflated plants 

 are many smaller plants destitute of the swelling. 



124. Eriogonum glandulosum Nutt. Montezuma Creek. 



125. Eriogonum divaricatum Nutt. Montezuma Creek. 



126. Eriogonum SALSUGiNOSUM Nutt. Montezuma Creek. 



127. RuMEX VENOSUS Pursh. Near the spring on the road 

 to Moab. 



128. Euphorbia flagelliformis Engelm. Young plants 

 of this were coming up, the old ones were near by, the dry 

 stems containing fruit, so the species could be determined from 

 all the material. Near the Grand River, in Court House Wash, 

 and on the San Juan flats. 



129. Celtis occidentalis E. Along McElmo Creek and 

 in the branch canons.
