norchis, Epipactis gigantea, an Oenothera and two species of 
Carvduus. One of the latter is evidently new to science. I also 
collected in San Juan Valley, as far as twelve miles in either 
direction and on top of the table-land, north of the river, and 
gathered many interesting plants. The flora is more like that 
of Arizona than that of the rest of Utah 
On August 30th, I took the stage northward and homeward. I 
stopped a single day at Moab to gather up some baggage and 
plants stored there and to pack my things for the railroad journey. 
On my trip home I stopped a few days each at the following 
places: at Denver to call on the Colorado botanists, Bethel, 
Ramaley, Cockerell and Osterhout; at Lincoln and Wahoo, 
Nebraska, my o omes, to visit old friends, and at St. Louis 
to study on the collection of Rosaceae at the Missouri Botanical 
Garden. I extend thanks to Dr. Trelease and Mr. Craig for 
many courtesies and help given. 
The result of the exploration cannot be given now, as the 
plants have not been determined. The collection contains many 
interesting and rare plants, as the region was practically a virgin 
fi only two botanists having visited it before and each only 
fora short time. Our collection contains nearly 6,000 sheets, 
representing 1,740 numbers of phanerogams, about 50 fungi and 
afew mosses and lichens. As some species were duplicated, being 
collected at more than one station, the number of species is some- 
what less. My estimate is somewhat over 1,000 species. 
Respectfully submitted,
