contributions to the flora of the West. His Flora of 

 Arkansas was never completed, but he mentioned many 

 plants in his Journal of Travels, and described others in 

 his Flora and other contributions (4, 5). The works of 

 Bradbury, Schoolcraft and Nuttall constitute the earliest 

 reliable records on the flora of Arkansas. 



In 1834 Featherstonehaugh traveled through Missouri 

 and Arkansas from the Missouri to the Red River. 

 Though his report (6) was largely geological, he made 

 frequent mention of many species of plants observed and 

 the types of vegetation encountered. 



In 1859 Professor Leo Lesquereux made a study of the 

 fossil and recent flora of the state for the Second State 

 Geological Survey, and gave a description of the botani- 

 cal features of the northern and northwestern counties 

 and a catalogue of Arkansas plants (8), including those 

 observed and reported by Nuttall. As Lesquereux did his 

 work during October-December and covered very exten- 

 sive territory, he probably did not assemble an herba- 

 rium. 



To this catalogue Butler added a list (9) of over a 

 hundred species in 1877. Prof. F. L. Harvey published 

 many short articles and notes in the Botanical Gazette 

 (10-15, and 17-29) between 1880 and 1885, including a 

 more comprehensive treatise on the Ferns of Arkansas 

 (17-18) and one on the arboreal flora (32). Harvey 

 began to assemble an herbarium. A large portion of his 

 collection is still preserved at the University of Ar- 

 kansas, and many of his duplicates were i wrhanged with 

 other herbaria. 



Professor R. Ellsworth Call, who was engaged in a 

 study of the geology of Crowley's Ridge, prepared two
