SUPPLEMENT TO THE CATALOGUE 
OF ARKANSAS PLANTS.* 
J.T. Bucunouz ano EB. J. Paumen. 
More than thirty-six years have elapsed since the pub- 
heation of a Catalogue of the Flora of Arkansas. We 
are presenting here the first supplement to the List of 
Arkansas Plants by Branner and Coville (35). Many 
plant names have been changed since this publication, but 
we are not attempting to include names in this list where 
mere changes in synonymy are involved, except in a few 
instances where these changes are such as would not be 
included with the synonymy given in current botanical 
manuals. Our supplementary list of plants presented 
here consists almost exclusively of additions to the for- 
mer catalogue and includes also the species reported by 
various other botanists, both in publications appearing 
since 1890, and from reports rendered privately to the 
Department of Botany of the University of Arkansas 
within the last six years. 
One or more collection numbers are given where pos- 
sible. However, collections made by J. T. Buchholz were 
usually not numbered, and when thus marked, all num- 
bers used by this observer are below 1000. Nearly all 
of these specimens are in the Herbarium of the Uni- 
versity of ‘Arkansas. Collection numbers of Arkansas 
plants by E. J. Palmer are those given with numbers 
above 4000, unless otherwise stated, and duplicate speci- 
mens of many of these plants are in the Herbarium at 
Fayetteville. Most of the early collections by Palmer
