126 Plants Collected in Southeastern Utah. [ZOE 
117. ATRIPLEX ARGENTEA Nutt. Along the San Juan 
River and elsewhere. 
118. ATRIPLEX NUTTALLII 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. Er1oconum THomasit Torr. Court House Wash, 
near Moab, growing along the rocky cafion walls. 
123. HRIOGONUM INFLATUM Torr. Common on the desert 
plains and the cafion 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 L,. Along McElmo Creek and 
in the branch cafions.
