SUPPLEMENT TO THE CATALOGUE 

 OF ARKANSAS PLANTS.* 



J. T. BUCHHOLZ AND E. J. PALMER. 



More than thirty-six years have elapsed since the pub- 

 lication of a Catalogue of the Flora of Arkansas. We 

 are presenting here the first supplement to the List of 

 Arkansas Plants by Brainier 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 earlv collections by Palmer
