Bibliographic Summary of Arkansas Field Botany
Over 750 references, compiled over the past five years, are presented on floristics, taxonomy, autecology, synecology, species biology, habitat analysis, impact analysis, paleoenvironment, phytogeography, and history of field botany in Arkansas. This bibliography is reported to facilitate efforts to document and interpret the flora, the vegetation, and the natural heritage of Arkansas and to encourage others to participate in that collective effort
Distribution, Abundance, Status, and Phytogeography of Log Ferns (Dryopteris: Woodsiaceae) in Arkansas
A study of the distribution, abundance, status, and phytogeography of the six taxa of Log Ferns {Dryopteris: Woodsiaceae) that are known to occur in Arkansas was conducted from 1981 -1986. Five of these ferns are generally quite rare in Arkansas. Except for D. marginalis, all exist in Arkansas as small, peripheral populations that are marginal, outlier populations to the west and south or west and north of their metropolis. Two sterile, triploid hybrid taxa (D. X australls and D. X leedsii each occur at only one locality, and there with but one of their parent taxa. The population of the putatively sterile hybrid D. Xaustralis has a large number of juvenile plants that were not asexually produced byrhizome expansion. The microhabitat of D. Xaustralls is suggested to favor gametophyte establishment. It is speculated that some level of pseudomeiotic spore production and/or apogamy may be involved in the production of numerous juvenile sporophytes
