360 A Trip through Southeastern Utah. 
divaricatus, and glandu/osus, several Astragali, Gilia pungens, 
Lygodesmia exigua and Cnicus Neo-Mexicanus were among the 
plants noticed on the rocky hills and cedar-covered mesas. Along 
the river bottom the grass was high and the trees near the water 
formed a low grove of box elders, willows and cottonwoods. 
Calochortus Nuttal/it was in bloom, and quite common. In general 
the plants were the same as those usually found not far from water, 
and as we approached the San Juan River the trees were replaced 
by Sarcobatus vermiculatus, Bigelovia graveolens, and Artemisia 
tridentata, so tall as to hide us completely from each other. They 
all make fine camp fires, but Sarcobatus is the best. We thought 
that we might also have to try them for internal combustion, but 
an Indian store on the San Juan River saved us from the attempt. 
Along the San Juan River the vegetation was not different from 
the lowlands of Montezuma Creek; some chenopodiaceous ‘plants 
were seen, but too young for determination, though as’ Grayia 
Brandegei was known to grow in that vicinity, all were closely ex- 
amined and found to be young Atriplices,, probably argentea and 
Nuttallit. Thickets of Forestiera Neo-Mexicana were hereand there, 
and Lyctum pallidum occasionally replaced the usual desert shrubs. 
The looked-for Grayia was not found until the McElmo Creek was 
reached, where many other interesting plants now appeared. Datura 
metelodes was rather startling.’ It is not supposed to grow so far 
north, but here it was abundant in the dry bed of the creek and 
occasionally along the sides. The seed pods are often found in the 
ruins of the ancient people who once filled this land and guarded 
every spring with towers of. stone. The hackberry, Celtis occidentalis, 
‘was a new and ungommon shrub; but the other shrubs were those 
found throughout the whole region. Cinothera Flartwegt var. lavan- 
dulefolia, was noticeable occasionally, and a few more new Astragali 
were found, as well as some other plants previously collected, such 
as Biscutella and Calochortus flexuosus. In Montezuma Valley the 
shrubs were in full ‘bloom, and the hillsides were beautiful with 
Peraphyllum ramosissimum, Fendlera rupicola and Amelanchier al-- 
nifolia. A single plant of the Grand Junction Chenactis scaposa 
was collected, which extends its range two or three hundred miles, 
the extent of country through which we had ridden during our ten — 
days’ trip. : 
The region traversed belongs mainly to what Dr. C. Hart Merriam
