Supplement to Catalogue of Arkansas Plants 95 
prairie and the coastal plain region of southeastern ‘Ar- 
kansas, containing names new to the state. More re- 
cently Dr. Harper and Rev. H. E. Wheeler sent us speci- 
mens representing unreported species, as credited to 
them. Others contributing data, specimens, or assist- 
ance in finding favorable collecting stations are: Mr. 
Ralph Shreve of Farmington, Prof. D. Demaree of Hen- 
drix College, Conway; Mr. W. W. Ashe of the Forest 
Service; staff members of the Agricultural Experiment 
Station, Fayetteville; some of the county agricultural 
agents and a number of former students of the Univer- 
sity of Arkansas. These miscellaneous unpublished 
records are included here with the name of the observer. 
From these, from some of our own publications, and for 
the most part from our other unpublished records, this 
list of additions to the catalogue of Arkansas plants has 
been prepared. A list of publications pertaining entirely 
or in part to the flora of Arkansas is given below. This 
is represented by a complete collection of these publica- 
tions, nearly all bound in eight volumes deposited in the 
University of Arkansas Library.
