VOL. 111.] 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 augustifolia was sending- up its flower-stalks; 

 on the mesas which we crossed, a Frasera, taller and more loosely 

 flowered than F. alboinarginata, was getting ready to bloom ; Berberis 

 Fretnonti hQc^.\we more common along water courses, and was beau- 

 tiful with the showy yellow flowers amid its holly-like leaves; 

 Psoralea castorea spread over sandy slopes. In a small canon we 

 found the greatest variety seen in one place, and collected AlHuni 

 Nevadense f Pcnstcinon Parryi, Ephedra trifurca in fruit, a small 

 flowered variety of Gilia congesta, an Arabis which is probably a 

 beautiful, rose-colored, large-flowered form of A. Holba'llii, found 

 also at Grand Junction, and the widely-distributed Krynitzkia 

 leucophoea, the only one of the spicate and glomerate Krynitzkias 

 that can be determined with certainty, because of its smooth, shining 

 nutlets. This caiion led up to a mesa covered with piiions and ce- 

 dars, and again we were in a region of few flowers, Penstcmon 

 Parryi, Gilia congesta, and Krynitzkia leucophoea h^'xwg almost the 

 only plants under the low trees. We crossed another pinon-covered 

 mesa, after leaving Monticello, and in that little-visited locality 

 found a few plants of Erodiuni cicutarim, the offspring of some dar- 

 ing pioneer. It was a great surprise, and the place at once lost 

 some of its wildness. Trifoliuni Plummcrce 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 Canon, intending to climb up the other side 

 and then ride acro.ss an unbroken mesa to McElmo Creek. Monte- 

 zuma Canon 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 canons 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 albomarginata , Cymopterus purpureus, Calo- 

 chortiis flexuosns, Poly gala acanthoclada, Eriogomim salsuginosus,
