MISSOURI BOTANICAL GARDEN BULLETIN 13 
America; Dr. J. R. Weir, 293 fungi of northwestern United 
States; Dr. Mary 8. Young, 146 plants of Texas. A complete 
list of accessions received may be found in the current num- 
bers of the BULLETIN. 
Mounting and Distribution —The mounting of herbarium 
specimens has continued through the greater part of the 
year, and most of the material received has been mounted 
and inserted in the organized herbarium. Sorting, identify- 
ing, and distribution of specimens, particularly those ac- 
quired in previous years, has edutinter throughout the year. 
Field Work.—The botanical survey of the Southwest in 
coéperation with the Arnold Arboretum of Harvard Univer- 
sity has been continued; but on account of war conditions 
and also because of the unusually dry season in the south- 
western states somewhat less time has been devoted to field 
work than in 1917. The Garden collector, Mr. Ernest J. 
Palmer, has visited numerous localities in Texas, Oklahoma, 
Arkansas, and Missouri. His itinerary from March 16 to 
June 30 and again from September 5 to October 12 has in- 
cluded the followin stations from which collections were 
made: Beaumont, Fletcher, Silsbee, Sour Lake, Houston, 
Velasco, Angleton, Palestine, Riverside, Grapeland, Mar- 
shall, San Augustine, Blanco, San Marcos, Uvalde, Chalk 
Bluff, Palestine, Larissa, Huntsville, Oakwood, Keechi, Col- 
lege Station, Fountain, Bryan, Kerten, Dallas, Uvalde, 
Barksdale, Crystal City, Byrd, Del Rio, Devils River, Boerne, 
Austin, Ft. Worth, Baird, Sweetwater, Colorado, Clyde, Post, 
Canyon, Paloduro Canyon, Gamble’s Ranch, Canadian, 
Channing, Stephenville, Johnsville, Strawn, Denison, in 
Texas; Muskogee, in Oklahoma; Webb City and Reding’s 
Mill, in Missouri; Cotter, in Arkansas; Branson and Galena, 
in Missouri; Palestine, Grapeland, Larissa, San Augustine, 
Uvalde, Chalk Bluff, Smyth’s Ranch, Post, Canyon, in 
Texas; Oklahoma City, in Oklahoma; Texarkana, in Arkan- 
sas; Fulton, McNab, and Noel, in Missouri. Most of these 
stations were visited twice in order to secure, as far as 
sible, both flowering and fruiting specimens of the early and 
late-blooming plants. Notwithstanding the dry season, 
nearly 8,000 specimens were obtained which furnish excel- 
lent material for our studies of the flora of the Southwest. 
Fruit and seeds of a number of plants were collected which 
can be grown to advantage in the Garden. 
Exchanges.—Several important series of herbarium 
specimens have been received from various institutions and 
ifferent individuals on the basis of exchange, but no general 
distribution of duplicate herbarium specimens has been made
