Supplement to Catalogue of Arkansas Plants 93 
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 snd 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 exchanged with 
other herbaria. 
Professor R. Ellsworth Call, who was engaged in a 
Study of the geology of Crowley’s Ridge, prepared two
