VOL, Ht.] A Trip through Southeastern Utah. 359. 
The following day was more profitable in the number of plants 
collected, but as quantity does not always make up for quality, it is 
doubtful whether it was really more successful. Here and there 
on the hillsides Yucca angustifolia was sending up its flower-stalks; 
on the mesas which we crossed, a Frasera, taller and more loosely 
flowered than /: aébomarginata, was getting ready to bloom; Berberis 
Fremonti became more common along water courseés, and was beau- 
tiful with the showy yellow flowers amid its holly-like leaves; 
Psoralea castorea spread over sandy slopes. In a small cafion we 
found the greatest variety seen in one place, and collected Ad/ium 
Nevadense? Penstemon Parryi, Ephedra trifurca in fruit, a small 
flowered variety of Gzlia congesta, an, Arabis which is probably a 
beautiful, rose-colored, large-flowered form of A. Holbellii, found 
also at Grand Junction, and the widely-distributed Avynitzkia 
leucophea, the only one of the spicate and glomerate Krynitzkias 
that can be determined with certainty, because of its smooth, shining 
nutlets. This cafion led up toa mesa covered with pifions and ce- 
dars, and again we were in a region of few flowers, Penstemon 
Parryi, Gilia congesta, and Krynitzkia leucophea being almost the 
only plants under the low trees. We crossed another pifion-covered 
mesa, after leaving Monticello, and in that little-visited locality 
found a few plants of Evodium cicutarim, the offspring of some dar- 
ing pioneer. It was a great surprise, and the place at once lost 
some of its wildness. 77ifolium Plummere seemed common, but 
was past its period of bloom, and almost of fruit as well. 
We were aiming to cut across country, because a cattle highway — 
was so barren, and after great difficulty succeeded in reaching the 
bottom of Montezuma Caiion, intending to climb up the other side 
and then ride across an unbroken mesa to McElmo Creek. Monte- 
zuma Cafion proved to be a prison from which we could not escape 
until we reached the San Juan River. Its walls were perpendicular 
for miles, and impossible to climb with horses. Whenever a hill - 
could be ascended, we toiled up and led our poor animals, only to 
behold a labyrinth of cafions beyond. However, as we continued 
to find new plants and were exploring country perhaps as pioneers, 
we somewhat forgot that our stomachs were empty and our provis- 
ions low. Frasera albomarginala, Cymopterus purpureus,— Calo- 
chortus flexuosus, Polygala acanthoclada, Eriogonum salsuginosus,
