Glyptostrobus Europaeus (Brongn.) Heer In Arkansas, Eugene B. Wittlake
Glyptostrobus Europaeus (Brongn.) Heer In Arkansas, Eugene B. Wittlake
Journal of the Arkansas Academy of Science
Glyptostrobus europaeus (Brongn.) Heer, a fossil gymnosperm is found at a few locations in central North America, in deposits of the Eocene. This work cites previously reported localities and reports a new site at Hooker, Arkansas. This deposit appears to be the most abundant for specimens of G. europaeus in the Eocene of North America. History of the Hooker site, characteristics of the living species G. pensilis (Abel) Koch and G. europaeus is presented. Worldwide distribution of both species through time, is discussed. Specimens of many parts of the life cycle of G. europaeus are recorded and illustrated.

Effect Of Domestic Effluent On Two Spring Surveys Of Fishes In Lost Creek, Craighead County, Arkansas, John K. Beadles
Effect Of Domestic Effluent On Two Spring Surveys Of Fishes In Lost Creek, Craighead County, Arkansas, John K. Beadles
Journal of the Arkansas Academy of Science
Lost Creek is representative of deltonic streams of the St. Francis Basin possessing characteristics of being turbid. It has a low flow velocity except during the annual spring rains. Lost Creek meanders approximately 18 km. before receiving effluents and empties into Big Creek approximately 4 km. west of Jonesboro, Arkansas. Five collecting stations were studied in 1966 while six stations were sampled in 1970. Some fishes have been found to tolerate moderate amounts of domestic effluents and it is probable that the two species Lepomis cyanellus and Ictalurus melas, collected within the effluents, were more resistant than the other species …

Survey Of The Arkansas Campanulaceae (Including The Lobeliaceae), Edwin B. Smith
Journal of the Arkansas Academy of Science
This paper is a summary of the Campanulaceae of Arkansas, based on the material on file in the University of Arkansas herbarium. A key to the species is included, followed by an alphabetical listing by genus and species of the taxa in the Campanulaceae known to occur in the state. After each taxon, the following information is included in this order: blooming period (as indicated on our material), known distribution in general terms (NW-northwest, E-east, G-general, C- central, etc.), habitat, chromosome number (as reported in Darlington & Wylie, 1955; in the Index to Plant Chromosome Numbers, Vol. I.II, and Supplement; …
